Over mij
Java backend developer building secure, production-ready REST APIs with Spring Boot. Two complete backend systems designed, tested and deployed.

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.
