What I'm looking for

I'm looking for backend and architecture work where I can build production systems, improve legacy platforms, and turn operational processes into reliable product flows. I’m open to remote EU roles or hybrid work one to two days per month.

At Service Club, I'm a founding backend architect building the core vertical and a live marketplace for a large client. I migrated the platform to a NestJS modular monolith so the business could support more verticals.

I turned enrollment and back-office work previously handled in Excel into automated product flows, using TypeScript, PostgreSQL, DDD, CQRS, event-driven design, AWS, and GitHub Actions.

Previously at TIFIN, I reworked legacy backend systems for wealth advisory and portfolio products, shipping client MVPs in two to three months. At Facephi, I improved onboarding and KYC APIs by introducing DDD, Clean Code, and unit, E2E, and infrastructure tests.

I've also delivered production Vodafone in-app payments at Optiva Media and contributed to OTT products for national clients, including LaLiga, at Tyris Software. I work daily with Claude Code and Cursor through Spec-Driven Development, following a research, plan, and implementation approach.
