Fintech development
Payment flows, dashboards and integrations where correctness and data protection can't be an afterthought, built by a senior nearshore team in your time zone. Fixed pricing from USD $5,000, code that is yours.
The problem
Handling money and sensitive data with generic, sloppy engineering
We treat correctness and security as the foundation: encryption, access control, validation and tested backups, not add-ons.
Payment integrations that break or double-charge under load
Idempotent, verified webhooks and payment state as the source of truth, so a duplicate event never charges or confirms twice.
Privacy and compliance bolted on after launch
Privacy by design from the start, minimal data, clear access and retention, so protection is built in, not retrofitted.
Slow, far-offshore teams on time-critical work
A nearshore team in your hours, so decisions on sensitive flows happen in real time, not on a 24-hour delay.
What we build

A written proposal with a fixed price, and full ownership of your code and infrastructure, with no lock-in.
Yes. We build payment flows on proven gateways with idempotent, verified webhooks, and treat encryption, access control and privacy by design as the baseline for anything handling money or personal data.
We build the technical foundations, encryption in transit and at rest, least-privilege access, input validation, tested backups, and design privacy in from the start. For your specific regulatory obligations, we work alongside your legal advisors; we don't replace them.
Fixed project pricing, defined in a written proposal after a short discovery, split into milestones with verifiable deliverables. Projects start from USD $5,000.
