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.
Spring Boot services use PostgreSQL, Redis, OpenFeign, and Eureka. React Native powers the rider app, with Angular for operations and React for the public site.

A Spring Boot and Next.js application for creating and attempting quizzes, with JWT authentication, role-based administration, timed attempts, and automatic scoring.
MySQL stores quiz and user data. Redis handles token state, while dashboards expose attempt history and performance analytics.

Those are the ones worth walking through. The experiments, the half-finished, and the rest stay in the open.

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.
