      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 Nikita Vershinin

      We've partnered with Sigma Software for almost three years, and they proved to be a strong partner with whom we'll keep working. Their adaptability and willingness to get things done are unique, setting them apart from other providers. Moreover, they demonstrate a strong sense of ownership.

      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!

      Mobile App Development Review from Esther Howard

      The client is incredibly happy with Sigma's services and work. It has referred 3 other clients who also say how much they really love the team and process to get set up with the agency. Sigma is a fantastic company with excellent experienced professionals. Its experts care about quality and customer satisfaction, and they operate like the internal team's extension.
