The final product optimized the company's process as expected and has been well received by users. The company appreciated how well the Geeky Ants communicated, always punctual for meetings, and responsive to inquiries despite being in different timezones.
suresh's Review Sourced from Google
Candidates should carefully evaluate whether to participate in this interview process. Based on my experience, it seems the interviews are being conducted primarily for showcase purposes rather than actual hiring, leading to a significant waste of candidates' time, preparation, and effort.
Deekshu Gunaga's Review Sourced from Google
Very poor hiring management experience at GeekyAnts. After scheduling the interview and making candidates wait for one week, the hiring team only said the application was “on hold” and mentioned there may be an update next month. After that, there was no response or communication at all. Candidates deserve proper updates and professional handling instead of being ignored. It was worst experience

HDWEBSOFT did a fantastic work that aided the client in expanding their business, particularly in terms of growing website subscriptions. The project began on schedule and opened up a lot of opportunities for the business.

Using a smooth user interface, HDWEBSOFT effectively updated our landing page, enticing visitors to sign up for the product's waitlist. The staff provided a customized strategy and was incredibly responsive, driven, and enthusiastic. They also used ClickUp for project administration.

Mobile App Development Review from Max Levchin
We've partnered with HDWEBSOFT who have created our app using .NET. The feedback from our customers we've received has been overwhelmingly good. We had heard positive things about the idea even before we released the app, so it's encouraging to see those comments continue once it has been out. HDWEBSOFT was set up from the start. The design team was outstanding; they completed the job on schedule and within our allocated budget. They followed a well-defined procedure that was in place.

Mobile App Development Review from Noah Petraitis
AgileTech excelled in supporting our project from initial mock-ups through to the final delivery on the App Store, incorporating data analytics that we could easily share with our customers. The scope of work included mock-up creation, UI/UX design, interactive prototyping, app development, rigorous testing, and setting up a secure production environment on AWS, culminating in the apps release on both iOS and Android platforms.

Software Development Review from Selva Jayaraman
Working with AgileTech has been an amazing experience, especially when it comes to creating a personalized e-learning program for our IT services business. We were pleasantly surprised by how adaptable and scalable the platform developed by the AgileTech Team was. Their proficiency with user-friendly course administration and community participation technologies enabled us to provide a thorough instructional resource catered to our customers' particular requirements. The platform has greatly improved our operational efficiency, and we are amazed by its capacity to manage heavy traffic with ease and offer comprehensive reporting and analytics. The platform remained successful and user-friendly because of the team's dedication to continuous support and their quick response to criticism. For any organization looking to create innovative and reliable digital solutions, we wholeheartedly recommend AgileTech as a partner.

Software Development Review from Preci Capiral
AgileTech provided a superb Learning Management System (LMS) that creatively and precisely addressed the intricate needs of our organization. Within a scalable, completely customizable platform, the LMS made it possible to create comprehensive courses, administer student tests, engage the community, and obtain real-time data insights. AgileTech's modular and agile approach made sure that every component, from the user-friendly course builder to the sophisticated analytics and communication tools, was customized to meet our demands despite the difficulties of developing such a feature-rich system. In order to guarantee perfect scalability and zero downtime, even with high user concurrency, AgileTech used a potent tech stack that included PHP, React, and AWS. Their post-launch assistance, which included frequent training sessions and upgrades, gave our staff the means to fully use the LMS's potential. This project was a testament to AgileTech's technical skill, rapid deployment, and dedication, making them an outstanding choice for educational technology development.

UASOFTDEV Reviews & Testimonials

Software Development Review from Slava Kostiuk
We initially approached UASOFTDEV with a relatively straightforward request: a WordPress website and a Senior React/Node/Python Developer for backend and API development. What impressed us immediately was how quickly they understood our needs and delivered relevant candidates. We received the first 5 candidates within 60 hours, exactly as promised. The developers were skilled, experienced, and cost-efficient, so we decided to continue working with UASOFTDEV. Later, we returned with a much more complex project: an already-live AI beauty ecosystem combining a Smart Mirror, mobile app, AI skin analyzer, and AR makeup. This required a Senior Flutter Engineer who could join an existing team and work with Flutter, Banuba SDK, Java/native technologies, and a production environment. UASOFTDEV matched us with a senior Flutter engineer within 60 hours. He integrated quickly into our existing team and provided the 24/7 production support we needed. During the 5.5-month engagement, we delivered 10+ major features, shipped 15+ releases across 3 product environments, and launched 2 premium subscription features. What we valued most was the consistency of their approach. Production issues and new feature requests were handled quickly, communication was personal and responsive, and the team remained highly engaged throughout both projects. The fact that we came back to UASOFTDEV with a second, significantly more technically demanding AI/AR project is probably the strongest proof of our satisfaction. They successfully scaled from a simple staffing request to supporting a complex live product without losing the same level of responsiveness, quality, and personal attention.

DevOps Consulting Review from Khrystyna Sliana
We hired a DevOps engineer from UASOFTDEV to handle a multi-entity AWS infrastructure split. The project was completed on schedule, with zero downtime and great attention to security and data integrity. Recommended.

Dedicated Team Augmentation Review from Leonid Viktorov
I am the CEO of Biz Adviser, a business consulting company. We work with companies on strategic business initiatives, digital transformation, and improving business performance. We partnered with UASOFTDEV when we urgently needed additional engineering capacity. I was looking for proven senior developers and did not have time to spend weeks sourcing candidates and conducting multiple interviews. UASOFTDEV offered to provide vetted Ukrainian developers within 60 hours, which was exactly what we needed. The team provided senior engineers with strong technical expertise and excellent communication skills. We worked with developers across PHP, Node.js, Python, and React, depending on the project requirements. They were reliable, proactive, and able to understand not only the technical tasks but also the broader business context. The developers contributed to several important initiatives, including the implementation of an AI agent, and helped us move projects forward faster while keeping development costs under control. UASOFTDEV delivered what they promised. The process was straightforward, communication was reliable, and the developers were able to start working quickly without compromising on quality. The pricing was a good fit for our budget, and the overall value for cost was excellent. I also appreciated the cultural fit and the team's ability to communicate effectively and take ownership of their work. I would definitely recommend UASOFTDEV to companies looking for reliable staff augmentation with senior Ukrainian developers. They are a trustworthy partner that can provide strong engineering talent quickly and help businesses deliver important initiatives without the overhead of a lengthy hiring process.

RichestSoft Reviews & Testimonials

Web Development Review from Lathan Ashton
RichestSoft was tasked with taking our existing templates, upgrading them to the latest version of our CMS, and deploying them to a staging environment. They also updated the designs for all subsections of the site. The site is fairly generic, consisting of static pages with links from the homepage to product descriptions, case studies, and more. Our team can easily log into the CMS and update case studies without needing a web developer, which has been a huge advantage. Our primary concern was the seamless conversion of our old templates, and RichestSoft handled this flawlessly. They even suggested ideas like making the site multilingual, though we only needed an English version, so it wasn’t necessary in our case.

Web Development Review from Robbie Hart
The website now has a more modern and appealing feel, and we've noticed an increase in the number of visitors since working with RichestSoft. They effectively leverage their technologies, and their communication and timeliness have been satisfactory throughout the project. Our business is centered around land development and industrial projects, supported by a team of IT professionals that manage the technology driving our operations. Our mission is to provide quality and satisfaction by utilizing our knowledge, experience, and ambition to meet and exceed our clients' expectations.

Web Development Review from James Shehan
RichestSoft consistently delivered on a complex and demanding project, handling all tasks with efficiency. Whenever any bugs or issues surfaced on the site, they promptly resolved them. While there have been occasional communication challenges, none of these have affected the high-quality and cost-effective service they provide.

Software Development Review from Dennis Temko
Dreamers was the only firm capable of building my ambitious vision for HyperCite. They transformed an unprecedented concept into a patented, production-grade legal technology platform designed for fact-checking. This included help in product strategy, and leading UX, algorithm development, AI, database and cloud architecture, frontend and backend engineering, scalability, observability, CI/CD, deployment, and ongoing maintenance. They delivered two California product versions and a dedicated Arizona implementation integrated directly with the appellate court, where HyperCite has operated for more than five years. Today, HyperCite not only automates hyperlinks between legal briefs and cited records; its AI fact-checking system compares claims against supporting evidence, flags contradictions and unsupported assertions, and takes judges and attorneys directly to the underlying source. The result is faster, clearer, and more reliable judicial review, delivered through close collaboration with HyperCite’s leadership and the Arizona court CIO.

The App Founders Reviews & Testimonials
Walter White's Review Sourced from Google
Initially, The App Founders showcased a pro-found grasp of blockchain technology and its practical applications. They adeptly elucidated intricate concepts in a manner that resonated with my non-technical background, facilitating smoother communication and active involvement in developmental discussions.
Dustin Wheeler's Review Sourced from Google
it was such a pleasure working with App Founders and just how easy and professional they were. I quickly realized how the industry is full of thirsty, needy bots and scammers I’m trying to get your attention, but tons of unsolicited phone calls and texts. Dealing with these guys was a breath of fresh and definitely showed up in value above all the rest.
Munna Alam's Review Sourced from Google
Got to say, The App Founders really impressed me! They totally nailed the design for my mobile game. Can't wait to team up with them again to make and promote the game. Definitely recommending them to anyone looking for top-notch game development services!

Nathan Dyer's Review Sourced from Google
As a result of our engagement with Bluelight Consulting, we are saving hours of developer time every week. We are able to deploy several times a day to multiple environments and going forward we’re going to better position ourselves as a company that offers tools that provide timely solutions for our internal users, which is what we pride ourselves on. There has been a tremendous lasting effect without a doubt. They meet set timelines within budget, keep clear communication lines, and are more than ready to address any emerging issues in a timely fashion. You can sense a sincere desire to meet our needs to the letter. It makes a huge difference. I must say we’ve worked with other vendors before where their ego was much bigger than working with us.
Emily Lien's Review Sourced from Google
Our cooperation with Bluelight Consulting worked out very well. Their experts find the right solutions for various problems, they work quickly, provide the right people for each job, and offer valuable suggestions on how to improve the product. Their flexibility and ability to adjust to our situation was the most important factor for the success of the project.
David McCulloh's Review Sourced from Google
After a thorough search for the best DevOps-as-a-Service companies in the US, and based on testimonials from past clients on their website, we felt the Bluelight Consulting team was the right choice to collaborate with on this project. And from the moment we booked a discovery call with them, we knew we had made the right choice. Thank you Bluelight Consulting!

ReVive Elite Care's Review Sourced from Google
We began working with TurnKey Digital in October, and our website officially launched in April. During our initial search, we spoke directly with the owner, who was knowledgeable and made us feel confident moving forward.Their team was responsive, professional, and highly collaborative throughout the process. As detail-oriented partners, we appreciated their patience and willingness to refine everything until it was exactly right.They delivered a beautiful logo and a cohesive website that truly reflects our brand. We’re extremely happy with the result and would highly recommend Turnkey Digital.
John Tanenbaum's Review Sourced from Google
My experience began in the planning stages back in the early spring of 2025 and every two weeks during the first 2 months we were in contact as the project took shape to develop the website. As the project progressed, we were having either weekly meetings or emails which accelerated the process. The last 6 weeks we were in constant contact, and the final end product was better than what we originally had hoped for our website. I can highly recommend Turnkey Digital to plan and execute your projects too. I am sure we will be utilizing their services in the future. John M. Tanenbaum, Castle Bay Management Services, LLC.
