Focus

Backend-first engineer, full-stack in practice. The parts I care most about are the unglamorous ones: data modeling, authentication and authorization, multi-tenant isolation, migrations, and tests that prove invariants instead of assuming them, shipped across a production mobile app, multi-tenant SaaS, and self-hosted infrastructure.

Right now I'm going deeper into distributed systems on large-scale financial infrastructure at my day job: services that have to stay correct under concurrency, partial failure, and real load.

Agent security is the newest thread: tool integrity, audit trails, and policy enforcement for AI agents: the same backend discipline, pointed at a new class of systems.
