Software Development Review from John Armstrong
ELEKS was able to take our vision and help us deliver an app that empowers retail shareholders to make their voices heard. They’ve brought a depth and breadth of technical expertise and user experience design to challenge us on our assumptions on how people would want to interact with the app. From a mobile development perspective, we wanted to go to market with both an Android and an iPhone simultaneously.
Software Development Review from Mark Battcock
We are very happy with our ELEKS partnership; the dedication of the team is exceptional. We would certainly recommend ELEKS and would be happy to work with them again. In fact, they continue to be our partner for the 2nd phase of the CDX project to add even more customer services to the website.
Software Development Review from Huntly Christie
What impressed me about ELEKS is the culture. There is a very strong culture of discipline and performance, and software is a profession where discipline is very important. Good software development can only happen with a strong work ethic, and I think the ELEKS team really understands that.

WordPress Website Design Review from Michael Hamilton
Digital Silk was an exceptional partner in the design and development of NeuroAnimation's new website. Their team was very responsive and worked hard to accelerate the project to fit within a tight timeline. One thing that stood out while working with Digital Silk was the effort they invested in understanding our very unique business.

We are looking forward to continue our relationship with Digital Silk and would highly recommend them.

Software Development Review from Anonymous
We had created a conceptual framework to authenticate and verify the provenance, transaction history, and authorship of blockchain-based NFTs. Talentica was brought on board to test and refine the concept from both functional and engineering perspectives, and later to build a Minimum Viable Product (MVP) aligned with the agreed specifications and constraints.
Software Development Review from Anonymous
For several years, the team was composed entirely of Talentica contractors. Since January 2022, I have been directly managing them. The Talentica team handled the admin tooling backend, which included multiple Python Flask services with Postgres and Elasticsearch. These services operated in a service-oriented architecture deployed on Kubernetes, using Istio for service mesh and Spinnaker for deployments.

Monica's Review Sourced from Google
Amazing and talented people. I’ve worked for both client and agency side and can can say their partnership is amazing. They truly care about ongoing operations and not just ending it at a project level. Highly recommend! Message me if you want specifics.
John Andesilich's Review Sourced from Google
I own a marketing firm in Troy MO and I recently met with Calvin at Sketch Development Services to discuss a software development project I have been thinking about pursuing. He was very nice, easy to speak to and even though his field is a bit out of my knowledge base, he was able to explain things in a way that made perfect sense. I look forward to working with him and his team in the future and recommend anyone looking for a software or app development company to give them a try.

Software Development Review from Filip Suskovic
Takeaway Reality developed our custom software exactly according to the specifications we provided. We shared images and videos with them, and they transformed that into a VR platform where people can view their apartment or house. Users are able to explore the property through a fully virtual walk-through.
Mobile App Development Review from Marie-Laure De Veyt
We set out to build awareness around a new cyber safety product. After reviewing several agencies through an RFP, we chose TAR because they fully understood our objectives and had a clear plan to achieve them. From brainstorming to final execution, we collaborated closely and collected feedback in an organized way. Working with TAR has truly been an outstanding experience.

We were informed about every major step in the process and it really made everything much easier. Takeaway Reality’s work delighted the client. Their dedication to the project accentuated their deep and relevant knowledge of VR and AR. Their communicative and transparent approach resulted in methodical project management. They went above and beyond to optimize the solution.
