About this gig

Are you looking for a quick fix or a failure-proof system?

If you want a cheap drag-and-drop site, look elsewhere. I am an Elite Full-Stack SDE specializing in Java (Spring Boot 3.x) & Angular 13+. My focus is strictly on the internal mechanics of high-performance distributed systems.

I don't just make code "compile." I architect backends that are ACID-compliant, secure, and optimized for high-concurrency environments.

Engineering Standards:

  • Backend: Spring Boot Microservices, JWT/OAuth2, API Gateways, and optimized PostgreSQL transactions (eliminating N+1 inefficiencies).
  • Frontend: Angular 13+, RxJS state management, and zero-lag UI rendering.
  • Enterprise Rigor: As an active contributor to open-source core banking ledgers (Apache Fineract), I resolve complex architectural logic gaps where race conditions destroy data integrity.

What I Deliver:

  • Secure REST API development.
  • Enterprise full-stack web apps.
  • Monolith to Microservices migration.
  • Refactoring failing code into clean logic.
  • Stop paying for code that breaks in production. Message me your requirements before ordering so we can audit your system design.
