      Web Development Review from Philip Wilson

      ELEK+RIK team provided a streamlined process that was both simple and enjoyable. They kept to the budget and communicated well throughout the project. ELEK+RIK comes highly recommended and we would work with ELEK+RIK again if given the opportunity.

      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.

      Software Development Review from Michael Meyer

      We were so positively surpised and happy about Sigmas services - as usual I might add. It is a pleasure working with their software engineers. After we provided a briefing, the effort estimation came right away. Shortly after the project started we could see first tangible results. The code quality was excellent and comprehensive. Minor feedback was implemented right away. What can I say more: 10 out of 10 points!

      Small Businesses Website Development Review from Jarrell A. Green, MBA-DA

      AutomateNexus built our entire e-commerce website for KourtLit from scratch. We sell portable pickleball court LED projectors and needed a professional storefront that could handle orders, inventory, and customer communication. They delivered a modern, mobile-friendly site with a smooth checkout flow, backend database for order and inventory management, and automated email sequences for order confirmations, shipping updates, and follow-ups. They also set up our SEO foundation so we're positioned to rank for product searches. What stood out was their BYOK approach we own everything they built. No recurring platform fees, no vendor lock-in. They finished the entire project in July 2025 and handed it off with full documentation and training. If you need an e-commerce site built fast and built right, these are the people to call.

      AI Development Review from Arionne Patterson M.S.

      We hired AutomateNexus to build a new website for our boutique travel agency, and they delivered far more than we expected. Erin and the team built us a custom website, client portal, and admin dashboard from scratch plus set up automations that completely changed how we run the business. Before working with them, we were drowning in manual tasks: sending confirmations, chasing documents, following up with leads. Now most of that runs automatically. The client portal lets our travelers access their itineraries and documents anytime, and the admin backend makes managing bookings so much easier. What impressed us most was the strategic thinking. They didn't just build what we asked for they helped us rethink our entire workflow and showed us where AI and automation could save us time. We're saving 15-20 hours a week on admin work we used to do manually. Communication was excellent throughout, delivery was on time, and the final product exceeded expectations. If you're a small business looking to modernize your operations without getting locked into expensive monthly software, I highly recommend AutomateNexus.

      I reached out to Arseni to create a new professional website for my business after seeing his work and reading various reviews. If you are looking for a professional, affordable website for your business look no further. Arseni was very responsive, listened to all of our ideas and requests. After a few revisions, we had the finished product and the live website we were looking for in a very short period of time. I highly recommend Arseni and would gladly use him again for any future needs my business may need.

      I had the pleasure of working with Arseni who built and deployed a new website for our construction services company. The final result was tailored to our business model and delivered quickly as promised. Information and visuals are organized in a clean, professional format that renders beautifully on both mobile and desktop, with modern effects that set it apart from generic templates. All around professional experience, highly recommended — 5 stars.

Very professional, efficient, and easy to work with. Definitely recommend!
