01 — What I Do

Services

Focused expertise that delivers measurable results

Microservices Architecture

Design and implementation of scalable systems with Java/Spring Boot and REST APIs. Reduced coupling, faster deployments, and easier maintenance.

Cloud & DevOps

AWS migrations, Docker/Kubernetes containerization, and CI/CD pipelines. Less downtime, faster releases, and lower infrastructure bills.

Performance Optimization

Diagnostic and tuning of production systems. I've delivered up to 14% CPU efficiency gains and built global error handlers for mission-critical microservices.

Production Support & Stability

Log analysis, incident resolution, and stabilization of critical servers. Experience with regulated financial environments like Barclays Bank.

Full-Stack Development

End-to-end web and mobile applications. From backend architecture to polished frontends — shipped and ready for real users.

Technical Mentoring

Team training, code reviews, and establishing best practices. I help junior developers grow into solid engineers who write clean, maintainable code.
