About this gig

Are you looking for a secure, scalable, enterprise-grade application? I am a Senior Engineer with 4+ years of experience architecting high-performance systems for FinTech and Aviation.


I specialize in Java 21 and Spring Boot 4 backends paired with any modern front-end framework (React, Angular, or Vue) tailored to your needs. I have a proven track record of reducing API response times by 40% and automating complex workflows.


What I Offer:


  • Frontend: Responsive UI/UX using your framework of choice with seamless API integration.
  • Advanced Backend: Robust APIs built with Java 21, Spring Boot 3, and WebFlux.
  • High Performance: Expert implementation of Kafka for event-streaming, gRPC for low-latency, and GraphQL.
  • Security: Advanced JWT-based RBAC (Spring Security 6) and end-to-end encryption.
  • Database & Caching: Optimized PostgreSQL/MySQL with Redis for high concurrency.
  • Reporting: Automated PDF/Excel generation (Jasper Reports).
  • DevOps: Full containerization with Docker and CI/CD setup.
