Here are selected case studies of what we've done!

These studies aren't a catalogue of everything we've touched. They're the projects that show FreySoft doing the work regulated fintechs and data-intensive businesses can't afford to get wrong: cross-border payment corridors, high-throughput transaction platforms, and the data systems that keep them fast and auditable. Every engagement here was scoped to a fixed outcome, staffed with senior engineers only, and judged on production results — uptime, throughput, transaction volume, migration risk — rather than activity or headcount.

We selected them to cover the three problems clients bring us most often. In payments, that means building and owning corridor logic, orchestration, and reconciliation across multiple rails, currencies, and jurisdictions. In data, it means migrations, master-data platforms, and pipelines that stay reliable as volume compounds. In modernisation, it means rescuing stalled or handed-over builds, hardening fragile APIs, and moving legacy systems to production-grade without pausing the business. The pattern is the same across all three: we own the outcome, not just the tickets.

Each case explains the situation we walked into, the decisions we owned, the constraints we worked under, and what measurably changed once the work shipped. If your challenge resembles one of these, use the filters to narrow by industry, expertise, and region — or talk to us and we'll point you to the closest parallel and the engineers who delivered it.
