Diffco built a complex, production-grade AI agentic system and backend for our client's fintech platform owning architecture, AI/ML components, and AI agents in a security- and compliance-sensitive environment.

Deep AI/ML and senior backend expertise. We'd happily work with them again.

Software Development Review from Elizabeth Sheehan

Our main goal was to update our web presence to more accurately represent our proficiency in IT consulting and services. Our prior website was disorganized, had poor performance, and failed to adequately convey our expertise in customer relationship management (CRM), customer communications management (CCM), and content management systems (CMS). We required a highly functional, aesthetically pleasing, and scalable website that could captivate users, offer smooth navigation, and blend in seamlessly with our current technology stack.They have perfect attention to detail. They took care of everything, from making sure the font and color scheme matched our corporate identity to making every user interaction as efficient as possible. The outcome was a website that serves as a potent instrument for business expansion in addition to being aesthetically pleasing. They were always helpful and quick to respond when we had questions after the launch.

Mobile App Development Review from Tim Nguyen

Warning: Avoid Apptunix (apptunix.com) If you're considering hiring offshore developers, especially from India, I want to share a warning about Apptunix (apptunix.com) and its CEO. My company worked with them on a development project, investing close to $40K, only to have them hold our code hostage and demand more money before releasing it.We entered into the project with clear expectations and milestones, but as we progressed, Apptunix consistently delayed, under-delivered, and eventually refused to hand over the work we had already paid for unless we agreed to pay more. This kind of behavior is nothing short of extortion. It seems like their CEO and leadership are more interested in squeezing money out of clients than delivering quality work.Beyond the financial frustration, the skill level and talent from this team were not up to par. The development work was substandard, full of bugs, and lacked the quality we expected for the investment we made. I strongly urge anyone considering offshore development to do your due diligence or, better yet, reconsider offshore development altogether, as the experience in some regions, particularly India, seems to be in decline.

Staff Augmentation Review from Sergey Novik

Were developing an internal image processing tool for our design team and needed two machine learning engineers, since our core developers were busy with other client projects. We required extra hands familiar with Python and computer vision, so after a developers market review, we hired them from SumatoSoft.The SumatoSoft developers joined our team and were able to swiftly adapt to our workflows, which resulted in them delivering the working models well before our hard deadline.Communication was straightforward throughout the engagement. We had video calls and exchanged brief text updates on a weekly basis. The delivered code is clean, and pull requests are well-documented.I appreciate that they pushed back on a few of our initial architecture ideas. They challenged our original approach and proposed a better method for handling the model weights. We plan to bring them back for the next phase of development.

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.
