      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!

      Digital Marketing Review from Undisclosed

      On a scale of 1-10 with 10 being the highest rating, I rate D2 a 10. As someone who worked at an ad agency/PR firm, I know how hard it can be to meet a client's expectations, yet D2 has done that and more with us (the Rail team at ODOT). I look to them for expert advice and recommendations, outstanding and effective creative, and responsible fiscal decisions—and they deliver finally, I know they will be our advocate in trying to help us accomplish our goals. and that is ultimately why I highly recommend this organization!

      Our law firm website was pretty outdated. Nirvana Canada completely redesigned it, starting with a clean Figma layout and then doing the front-end coding. They optimized the CSS and JavaScript so the pages load instantly on mobile phones. The user experience is 10 times better now.
