Chi sono
Java backend developer building secure, production-ready REST APIs with Spring Boot. Two complete backend systems designed, tested and deployed.
StockXpress: JWT auth with refresh-token rotation, role-based access, concurrency-safe stock updates.
JMeter load test: 100 simultaneous orders on 5 units gave exactly 5 successes, zero overselling.
BookIt: 50-endpoint booking API with seat-conflict handling. Cut cold-start latency from 50-60 seconds to 20-50 milliseconds.
I help with Spring Boot APIs, JWT security, PostgreSQL/MySQL, bug fixing and Docker deployment.
