I’m a software engineer. I work mostly in Java, Spring Boot, and PostgreSQL, and build with Flutter or React when I own the interface too.

A microservices transport platform for NFC and QR tap in and out, digital fares, trip and route management, offline verification, and live vehicle tracking.

A reusable authentication and authorization service with RBAC, ABAC policies, hierarchical scopes, explicit denies, and per-resource grants.
RS256 access tokens are verified through JWKS. Refresh-token rotation, reuse detection, Redis-cached decisions, and partitioned audits cover the failure paths.

A support chat where a bot answers first and a person on the team takes over in the same conversation. The customer chat and the agent console both go into any site or dashboard with one script tag.
Spring Boot keeps conversations in PostgreSQL and pushes them live over WebSockets. Optional AI answers come only from the company's own documents, searched with pgvector, and the server drops any answer that doesn't cite them.

I build the parts software users are not supposed to notice.
Queues, indexes, migrations, and services that need to stay understandable after deployment. Most days I am in Java, Spring Boot, and PostgreSQL. I like small interfaces, boring relational schemas, and logs that answer the first question.
