Need help fixing a slow API, production issue, or building scalable microservices? I can step in quickly and deliver. I'm a Java Backend Architect with 12+ years of experience building enterprise-grade systems across Telecom, Insurance, and E-commerce — systems handling millions of transactions daily with zero tolerance for downtime. In one recent engagement, I reduced API response time by 60% on an insurance platform processing 2M+ daily transactions by re-architecting the service layer with Spring Boot and Kafka-based event streaming. 🔧 What I can do for you: Fix slow or broken APIs and production issues Build scalable microservices using Spring Boot Design clean and reliable REST APIs Implement secure authentication (OAuth2, JWT, Keycloak) Modernize legacy systems 💡 What makes me effective: Hands-on from day one — no ramp-up time needed Strong debugging skills — I identify root causes fast, not just symptoms Real production experience at scale across regulated industries Clean, maintainable, production-ready code every time 🚀 To reduce your risk: Start with a small task or bug fix — see how I work before committing I'll review your system and flag issues immediately I can share working demos of similar implementations 💻 Tech Stack: Java, Spring Boot, Hibernate, JPA Angular / React, TypeScript Kafka, MongoDB, Oracle Docker, Kubernetes, AWS If you need someone who understands your system in hours, not days, and delivers without hand-holding — let's connect.
