      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.

      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.

      We worked with CIDT on building a web3 tax module for our platform. The team created the full backend: blockchain data processing, NFT and DeFi event detection, VAT logic, and reporting. Communication was easy, and we always talked in Slack with regular Zoom calls to check progress. The system works stable and fits well into our product. We had some extra design iterations, but the team handled them quickly. Overall, it was a good and smooth cooperation, and we are happy with the final result.

      Blockchain Review from Hanna Korovianska

      We partnered with CIDT to integrate a cryptocurrency payment module into a custom eCommerce platform we were developing for one of our clients. Our goal was to add a secure and seamless crypto payment option without disrupting the existing checkout flow.The CIDT team handled everything related to blockchain integration from wallet connections and smart contract setup to documentation and testing. Their work was well-structured, efficient, and fully aligned with our development process.A special mention goes to Ramil, CIDTs CTO, whose technical expertise and leadership were outstanding. He guided our team through the blockchain-specific parts of the project, explained complex concepts in simple terms, and helped ensure that the solution was both reliable and easy to maintain.All milestones were delivered on time, communication was smooth, and the final integration performed flawlessly. Within the first three months after launch, over 3% of transactions were completed via crypto payments, with a higher average order value than traditional methods.Overall, working with CIDT was an excellent experience. Theyre a professional, knowledgeable, and trustworthy team, and we look forward to future collaborations.

      Consumer IoT Review from Mason Ferlic

      GripFusion is a sports technology startup developing Tactile Intelligence. Our flagship product, the ForceBall, is the first grip-sensing baseball. We approached Atomic Object with the challenge to build a React Native iPad app to connect with the embedded electronics over BLE and visualize sensor data in real time. Atomic stepped up to the plate and hit a home run! They took early R&D code and we're able to successfully navigate IoT challenges, large amounts of sensor data, and seamless UX. The developer team worked closely with our technical staff to incorporate evolving firmware and hardware improvements. The design team did hundreds of hours of user discovery and product feedback to ensure we deliver a cutting-edge experience. Overall, Atomic has the breadth and depth to tackle complex hardware-software systems.

They've built this company the right way. An impactful community leader and employer of choice.

      As a freelance Video Producer, I recently wrapped up another fun project with the folks over at Atomic Object, and I've gotta say, it was an experience worth mentioning. Collaborating with their marketing team on a series of authentic and engaging customer-facing and internal videos was nothing short of fantastic. Their seamless planning and logistics during pre-production, coupled with easy going personalities during production, made the process a breeze. Post-production brought our collective vision to life with meticulous story editing and videos that reflect their unique culture and values. Their team's dedication to kindness, empathy, and diversity made this collaboration not just successful, but truly enjoyable.

      Seeing the restaurant i finally was able to stop in. I ordered the back potato with gumbo, seafood gumbo and crayfish pasta. The baked potato was mashed ok. But the gumbo appeared to have beeb microwaved. The crayfish pasta was inedible. The pasta was mush and it came with a mystery item. I had been hoping to catch this place open, but ended up disappointed. If the food has sat please inform your customers. Some of us have come out of our way to visit your restaurant.
