Chris Bailey Director at BAILEY SERVICES LTD
5.0★
Web Development Review from Chris Bailey
I engaged their web-development team to rebuild and modernize our company's manufacturing website, and the experience has been exceptional. From the outset, communication was clear and responsive: they took time to understand our industry-specific compliance needs and translated them into a site structure that is clean, secure, and easy to navigate. Delivery was on schedule, and the final result exceeded expectations pages load quickly, the design feels professional and trustworthy, and the content layout supports clarity for both clients and regulators.In addition, the team proactively suggested helpful enhancements: mobile optimization, streamlined navigation, and improved documentation pages all of which have already resulted in noticeably increased user engagement and lower bounce rates. They handled feedback promptly and implemented corrections without fuss, making the collaboration smooth and efficient.Overall, this project added significant value to our online presence, giving us a polished, modern website that accurately reflects our manufacturing standards and commitment to quality. I would gladly work with them again and recommend their services to anyone seeking reliable web development for regulated-industry clients.

We needed to have a custom guest communication platform built, due to our custom workflows at the business, connecting our team members with text, images, buildings and daily project tasks. Essential Designs was able to hit the exact deadline we had, to the day, and completed on budget. We continue to add on features, it's a good relationship.

Elizabeth Sheehan Sales Enablement Analyst at WayPath
5.0★
Software Development Review from Elizabeth Sheehan
Our main goal was to update our web presence to more accurately represent our proficiency in IT consulting and services. Our prior website was disorganized, had poor performance, and failed to adequately convey our expertise in customer relationship management (CRM), customer communications management (CCM), and content management systems (CMS). We required a highly functional, aesthetically pleasing, and scalable website that could captivate users, offer smooth navigation, and blend in seamlessly with our current technology stack.They have perfect attention to detail. They took care of everything, from making sure the font and color scheme matched our corporate identity to making every user interaction as efficient as possible. The outcome was a website that serves as a potent instrument for business expansion in addition to being aesthetically pleasing. They were always helpful and quick to respond when we had questions after the launch.

Big Data Analytics Review from Adam Leeman

Mubarak Muaz CEO at Aceplace

Software Development Review from Mubarak Muaz
A3logic provided software development based on the detailed briefing that we gave them, ensuring that every aspect aligned with our brand identity and user needs. They carefully analyzed our requirements, conducted research, and proposed design solutions that enhanced usability and engagement. A3logic was a very professional company. They managed the project well and delivered on time and within budget. They were very responsive and timely in their communication. I was impressed with how enthusiastic the A3logic team was about their work. They cared about my project and treated it as their own. They were a great team.

Software Development Review from Anonymous
I had the privilege of working with Ruslan and his team at Aristek for the past three years. It is hard to find that level of dedication in an offshore vendor/partner but Ruslan and the Aristek team deliver it. I would highly recommend Ruslan and Aristek to anyone needing an expert level partner in EdTech and SaaS platform development.

eCommerce Development Review from André Schörnig
We have been working with Dinarys on our Shopify store for quite some time, and the experience has been great. From the very beginning, communication was clear, efficient, and reliable. The Dinarys team consistently delivered detailed proposals, stuck to agreed timelines, and offered well-structured solutions tailored to our needs. Their technical expertise is impressive, but what really sets them apart is their proactive attitude and genuine commitment to our project. Whenever we had questions or changes, they responded quickly and constructively. Its a true pleasure to work with a partner who feels like an extension of our own team. Highly recommended!

Flyaps Reviews & Testimonials
Andrew Stetsenko Founder at GlossaryTech, backed by Dice
5.0★
Python Django Review from Andrew Stetsenko
We partnered with Flyaps to build the GlossaryTech Chrome Extension from scratch, including the backend for tech terminology analysis. The goal was to help recruiters, sales professionals, and other non-technical specialists in IT quickly understand the technical terms they encounter every day.The first release shipped back in 2017, long before today's AI tools were available off the shelf. Flyaps built a custom tokenization layer on top of NLTK library to resolve the ambiguity problem - distinguishing "Go" the language from "go to the shop," or "Swift" the framework from the adjective, while also correctly recognizing multi-token terms like "Ruby on Rails" or "Amazon Web Services". It was a pragmatic, precise solution that made the extension genuinely usable from day one.The outcomes have validated that early bet. GlossaryTech now holds "Featured" status in the Chrome Web Store, has passed 25,000 downloads, and consistently serves 10,000+ weekly active users and 2,000+ daily active users. For a niche professional tool, that level of organic, sustained engagement is rare - and it traces directly back to the technical foundation Flyaps put in place.Beyond the engineering, what stood out was how Flyaps engaged with the product itself. They contributed to architecture decisions, flagged edge cases early, and treated scope conversations with honesty rather than upsell. Communication was straightforward throughout, deadlines were met, and the codebase has held up well as we've extended the product over time.I'd recommend Flyaps to anyone looking for a partner who combines solid engineering with genuine product thinking. They've been central to GlossaryTech's success and continue to be a team we trust.
Dariia Ryzhova Product Manager at Nextgen
4.7★
Software Development Review from Dariia Ryzhova
Our collaboration with Flyaps has lasted for several major projects, of which I personally worked with them on two. I am very satisfied with the level of expertise (both technical and domain), the involvement and responsibility of the teams, and the quality of delivery. We successfully brought 2 major products to life together. Flyaps teams have diverse specializations, so I had the opportunity to attract consultants from different fields: software developers, including high-level architects, DevOps, QA, and business analysts.The teams have a modern technology stack and are experienced in Agile development. This allowed for smooth integration with internal teams and processes. It is also important to note that Flyaps provides technical consulting on demand, and this was very valuable service as well. Overall, I can recommend working with Flyaps as a reliable and high-quality partner.
ТОВ ХОТНАЙТС Review from Google

ТОВ ХОТНАЙТС's Review Sourced from Google
Flyaps delivered outstanding results for our e-commerce store! They built a visually stunning and high-performing website that perfectly captures our brand. Since launching, our site speed has improved by over 60%, and we've seen a noticeable increase in our conversion rate. Their team's technical expertise is top-notch, and the new admin panel they created has made managing our operations so much easier. I am happy to recommend this team of professionals.

I've worked as a contractor for several firms over the years. TopDevz really stands out above the others. They stay deeply involved throughout the project, maintaining regular communication with both client and contractor. This level of engagement really changes the nature of the project, making it a team-oriented approach rather than a simple contractor placement. This helps the project keep on track and insures that the contractor will keep busy. The people at TopDevz are all very friendly and helpful and I've been very happy working there.

Never fall for the positive feedbacks. I'm completely agree with the following comments which have low ratings. I have experienced the same kind of problem with this company. I strongly recommended to stay away from this company.If you really care about the mental health, Please stay away from this company.

Heads up to anyone looking at this place: they deleted a your comments if they're negative. Seriously, think twice before joining.I'm not kidding, avoid this company if you care about your mental health. Make sure you really read between the lines before you sign anything with this company.Don't fall for the positive reviews. It had given by the employees from the managements. It's all fake.It's just a really disrespectful environment. They'll keep stringing you along during your probation, saying they can't make it official until the project wraps. Then, the second it's done, they slap you with a PIP and suddenly your performance "isn't meeting expectations."They also expect you to work weekends regularly and don't give any comp-off for it. Oh, and they're doing another round of layoffs—for the second time! You'll never get recognition for your hard work, and you'll constantly feel like your job is on the line.Honestly, just do not join here. It's not worth it. And to whoever tries to delete this... well, let's just say it's pretty low to try and hide the truth about how they treated us.

Worst Place I’ve Ever Worked – Avoid at All CostsIf you care about your health, run. This company thrives on exploitation — 16+ hour workdays, weekends stolen, and deadlines that destroy any work-life balance. Management has zero empathy and treats burnout like a badge of honor. Expect to be working till 3 AM regularly while your mental health crumbles. No appreciation, no boundaries, no future.
