Artificial Intelligence
We hired Diffco to build a complex, production-grade AI agentic system and scalable backend for our client's fintech platform. The work spanned architecture, backend engineering, and applied AI/ML — including the AI agents that drive the platform's core intelligent functionality — all in a finance-grade environment with strong security and data-handling standards. Diffco owned the architecture decisions, implemented scalable backend services, and integrated the AI layer so it performed reliably in production. The project was delivered on schedule and within budget, and gave us a solid technical foundation we can confidently keep building on. What stood out most was their deep AI/ML expertise combined with senior backend engineering, and the way the team operated like part of our own — taking ownership, suggesting better solutions, and communicating proactively through regular syncs, in-person meetings, and Slack. Their speed and quality let us move faster than we could have with internal resources alone. The collaboration was excellent and we'd happily work with them again. Highly recommend Diffco for AI and complex backend engineering.
