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.

I had the pleasure of working with Colchuck Consulting on my organization's website and their expertise and customer service exceeded all expectations. They assisted me from initial conception all the way through our website launch, with an eye for detail. They helped me take my ideas and transformed them into a well-designed, user-friendly website that not only looks fantastic but also functions seamlessly. Additionally, their ongoing support and willingness to make adjustments along the way have been invaluable. As an entrepreneur starting a new project, working with them has been so helpful.
