Web Development Review from Ronny De Aza, P.E.
Andres from Absolute Web is a top-notch developer! He delivered a stunning website on time, exceeding my expectations. Highly recommended!

Web Design Review from Robert H. Hughes, CERP
Absolute Web designed a new site from scratch to replace our 20-year-old site. It was long overdue, and the process was made easy and manageable by Absolute. I spent months trying to find the right company to work with and found Absolute and Andres. He has been amazing and patient. After 5,000 products and new product images, his team got us to a polished and easy-to-use site. Their pricing was very reasonable and a great value. I would highly recommend Andres and Absolute Web.

AgileTech Reviews & Testimonials

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.

Workstream 1: research and product strategyWorkstream 2: ETP release Technology : Vendor use Flutter framework, which allows one programming language and one codebase to create two different apps (for iOS and Android). Clearly defined roles and responsibilities, communication is clearly and respectfully, very effective project methodology, trying to understand every time how their activities fits into mission of Modra zavarovalnica, respect each member of team, etc.

Software Development Review from Claus-Peter Mueller
We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork.The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

Mobile App Development Review from Dr. Lesley Kirkpatrick, MD
I had a great experience working with Tepia. Abraham, the Founder and CEO, was available, helpful, and actively involved throughout every stage of the process. Kimmy, my assigned project manager, was organized, responsive, and clear in her communication from start to finish.They anticipated potential obstacles before they became issues and approached everything with a thoughtful, solutions-oriented mindset. The team was consistently proactive, professional, and transparent. I truly appreciated their structure and ability to keep things moving smoothly. I would highly recommend working with Tepia.

Mobile App Development Review from Robert Beknazarian
Working with Tepia Co has been an exceptional experience from start to finish. They played a critical role in developing our mobile app for RELI, and I can confidently say they exceeded our expectations on every levelFrom day one, Tepia demonstrated a deep understanding of both the technical and business sides of app development. They didnt just execute tasks they asked the right questions, challenged assumptions when needed, and helped us think through complex workflows in a way that improved the final product. Their team truly operates as a strategic partner, not just a development vendor The communication was excellent throughout the entire process. We always knew where things stood, timelines were clear, and any issues or changes were handled proactively and transparently. For a project as complex as ours involving pricing logic, user flows, financing options, compliance considerations, and scalability this level of clarity and responsiveness made a huge difference.What really stood out was Tepias attention to detail and commitment to quality. The app they helped build is stable, clean, intuitive, and built with long-term growth in mind. They were thoughtful about architecture, performance, and future enhancements, which is critical for a company like ours that plans to scale aggressively.They were also extremely flexible and patient as our requirements evolved (which happens in real-world startups). Instead of pushing back, they collaborated with us to find smart, efficient solutions that aligned with our vision and budget.If youre a founder or business owner looking for a team that:Truly understands mobile app developmentCommunicates clearly and consistentlyThinks strategically, not just technicallyDelivers high-quality, scalable workI highly recommend Tepia Co without hesitation. They have been a trusted partner in bringing RELI to life, and we look forward to continuing to work with them as we grow

In each capacity I have found the entire team to be responsive, collaborative, and professional. They come prepared with new ideas and are always willing to try to find ways to advance our digital needs. I highly recommend.
Roberto Aponte's Review Sourced from Google
I am thoroughly pleased with your companies ability to deliver an exceptional working relationship that has lead to an eloquently executed client experience. Isadora Digital Agency took a much-needed concierge approach to our relationship and helped us define our goals as well as align the expectations of the officers of our company. Our needs and vision were sophisticated but you helped us to achieve our vision through a multitude of legal and compliance challenges while still creating a warm and textured environment for our clients to engage with us. There have been multiple occasions the agency has gone exceptionally above and beyond to make this project a success – had we partnered with some of the other 9 design companies we were engaged with, I don’t feel confident that they would have provided the white glove service that we received from your firm. Let me summarize: Isadora delivers enterprise style service and results with the client engagement and human interaction of a boutique firm.
