Kevych Solutions Reviews & Testimonials
Vasco Rouw
Founder at Mavelli
5.0★
Mobile App Development Review from Vasco Rouw
Weve been working with Kevych Solutions full-time for over a year, and the experience has been excellent. They handle the complete end-to-end development of our AI-powered mobile apps, including UI/UX, frontend and backend development, AI integrations, infrastructure, deployment, and ongoing support.
What stands out most is the extremely high level of their technical expertise and execution quality. They actively use AI and modern development workflows to maximize efficiency and deliver results quickly. The team is highly responsive, proactive, and always goes the extra mile to meet deadlines.
Since working together, we scaled from 0 to over 100,000 subscribers in just 8 months, and our apps are now generating more than $1M in monthly revenue. Whenever challenges came up, we solved them together efficiently, and Kevych Solutions continuously adapted and grew alongside our projects.
We highly recommend them to anyone looking for a reliable, high-level mobile app development partner.

Mobile App Development Review from Alex Kayaian
Kevych was amazing to work with, and an integral part of our team. They delivered on time, with high quality, and consistent communication. You can't ask for a better partner when developing a project.

Mobile App Development Review from Lucas Chatham
I had an excellent experience working with this engineering firm to build a React Native app. Oleg and Ihor were exceptional software engineerstheir technical skills were top-notch, and they consistently delivered clean, well-structured code on time.
What really set this team apart was Volodymyr, their CTO. He was incredibly hands-on, maintaining clear and frequent communication throughout the project. He was always responsive and proactive in managing the work, which made the entire process smooth and stress-free.
The team was professional, reliable, and genuinely committed to quality. They understood my requirements and provided valuable input that improved the final product. Highly recommend this firm for anyone seeking skilled developers and excellent project management!

Mobile App Development Review from George McKerrow
ELEK+RIK has worked on improving our React Native mobile app. We had the skeleton of an app, but they were able to do an end-to-end re-design of each of the main pages. Since then, they`ve successfully implemented around ~20 different features on our mobile app. We share a spec and design, they provide an estimate and occasionally some design options, then when completed create a PR on GitHub. Their code is well-organized, easy to follow, and rarely do we have to go back-and-forth about bugs. They are also excellent communicators - carefully following threads on Slack, effectively communicating design and engineering tradeoffs, and even producing a 10m Loom video walking through a diagram. Their communication is top-notch. They are super easy to work with even though we are on very different time zones. And, I am impressed at the speed and execution of their development.

Web Development Review from John Riley
ELEK+RIK was tasked with creating a website for our company from scratch. They were professional, communicative, and dedicated to delivering an exceptional website that perfectly captured the essence of our company while exceeding our expectations. They are a talented, reliable, and customer-focused web design and development company that I would highly recommend to anyone.

Yousra Saleh's Review Sourced from Google
We’ve had the pleasure of working with Cause of a Kind for a long time, helping them hire engineers for their projects, and they’ve been an amazing client throughout. They run a great dev shop, friendly, collaborative, and always building high quality work. We always recommend them to our clients who're looking for software agencies bec we know how they work and how they choose their engineers for their most sensitive projects.
I also recently sponsored a few episodes of their podcast Strictly From Nowhere, the content is excellent and Justin came super prepared with smart, insightful questions. Highly recommend them as both partners and creators.
Super friendly and smart guys

They are an exact fit for a very good client of mine who has been desperate to find a Dev Shop as qualified as this! Thank You Cause of a Kind!

Nestor Bernal Vidal's Review Sourced from Google
I strongly recommend COAK if you want to work with something more than a standard Software Development Studio.
For clients, COAK becomes a partner that helps to grow the business from the first day, from designing the solution until putting online using a sharp, effective, and agile business model. Anyone can code, but COAK, as a Software Development and SEO Studio, is beyond that. They know what they do, and they do it well.
As a developer, is a great place to learn and to share. It has the space and the agility that provides small companies but the focus and the effectiveness of a medium/big size company. The team is pretty diverse, but being a team member is not only to be a professional resource but a person with daily problems, and that is respected.
Mike and Justin know what the game's name is, and they play it very well.
