      AI Development Review from Oleg Sotnikov

      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. They delivered on time and within budget, communicated proactively, and operated like part of our own team, taking ownership and suggesting better solutions throughout. Deep AI/ML and senior backend expertise. We'd happily work with them again.

      eCommerce Development Review from André Schörnig

      We have been working with Dinarys on our Shopify store for quite some time, and the experience has been great. From the very beginning, communication was clear, efficient, and reliable. The Dinarys team consistently delivered detailed proposals, stuck to agreed timelines, and offered well-structured solutions tailored to our needs. Their technical expertise is impressive, but what really sets them apart is their proactive attitude and genuine commitment to our project. Whenever we had questions or changes, they responded quickly and constructively. Its a true pleasure to work with a partner who feels like an extension of our own team. Highly recommended!

      From my perspective as a former employee: I worked here for almost a year. Colleagues and staffs here are pretty open-minded but employees are highly underpaid. Also in order to get a job here you must have decent technical skills and English language ability.Pros: nice office, friendly staffs that really take care of employeesCons: underpaid salary
