About
I’m a full stack developer with 6+ years of professional experience, and I’ve spent the last couple of years shipping production SaaS products using Laravel and React. I’m especially proud of my end-to-end ownership approach—designing PostgreSQL schemas and queued background jobs, building typed API and domain layers, and delivering reliable, user-friendly React interfaces and mobile experiences.
In my recent work, I’ve developed a multi-tenant FX risk-management platform for corporate treasury, handling everything from role-scoped permissions and Stripe billing to reporting outputs and S3-based media handling. Earlier, I built an Office Verification System for the Department of Foreign Affairs, improving performance and maintainability in long-running internal systems—always with an emphasis on test coverage, monitoring, and maintainable engineering practices.

Maintain type safety by generating TypeScript definitions from PHP DTOs and enums, added Sentry monitoring, Inertia SSR builds, and PHPUnit feature coverage. Uses a branch-per-feature worktree flow with pull-request review, per-module documentation, and guard tests to ensure conventions and quality are enforced.
