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.

Nazim Eryilmaz's Review Sourced from Google
I worked with Nova Era on a UI/UX redesign for my startup and they were great to work with. If you’re local to the San Francisco area, Nova Era is an excellent choice and even if you’re not, it’s still seamless. I’m based in NYC and had zero issues with time differences or communication. Highly recommend the team.
Anıl Ergez's Review Sourced from Google
I worked with Nova Era Agency, a San Francisco-based web design agency, for a full website redesign and couldn’t be happier with the results. From the beginning, their team was professional, responsive, and clearly experienced in building modern, high-performing websites. They took the time to understand my business goals and delivered a clean, visually polished site that’s fast, user-friendly, and optimized for conversions.What really stood out was their attention to detail and clear communication throughout the entire process  from strategy and UX to design and launch. It felt great working with a local SF web design team that truly understands both branding and performance. If you’re looking for a reliable web design agency in San Francisco, I highly recommend Nova Era Agency.
Cevher Ersoy's Review Sourced from Google
i worked with Nova Era Agency, a San Francisco web design and SEO agency, to build a website for my online book business, and the experience has been outstanding. The site they designed looks great, is easy to use, and actually helps convert visitors into customers instead of just sitting there looking nice.I’m also using their ongoing SEO services, and the impact on my business has honestly been amazing. Over time, I’ve seen more organic traffic, better visibility on Google, and a noticeable increase in sales. It’s clear they understand SEO for online businesses, not just basic optimization.What I appreciate most is that they’re consistent and proactive. They don’t disappear after launch they keep improving the site and SEO month after month. If you’re looking for a reliable web design and SEO agency in San Francisco, especially for an e-commerce or online business, I highly recommend Nova Era Agency.

I've been working with Techjays since they started and have never been disappointed. On each project I have worked with them they have always delivered on time, on budget and with great quality. They adapt to the needs of the customer and have been in large part, more of a technical co-founder for my start ups. I'll continue to work with them and highly recommend them to anyone!

We've been working with TechJays the past 18+ months and the outsource experience has been great. They are agile and compared to previous outsource experiences, their competence, quality, and delivery punches above the rest.
