Specializing in high-throughput Spring Boot microservices, stateless JWT / RBAC security, and MySQL query optimization with zero auth production incidents.
I don't just assemble endpoints — I engineer resilient, high-throughput backend infrastructure. My core specialization focuses on Spring Boot 3, distributed microservices, Redis multi-tier caching, and MySQL transactional tuning.
I treat latency as a critical defect and security as non-negotiable. From designing stateless JWT authorization with granular RBAC to eliminating database query bottlenecks that slashed latency by 40%, every system I build is structured for fail-safe stability under enterprise workloads.
These selected projects demonstrate my focus on security, distributed architecture, and database performance — solving complex backend problems through disciplined engineering.
Enterprise-grade stateless authentication engine built on Spring Boot 3 & Spring Security 6 with Redis-backed token invalidation blacklists, dynamic role-to-permission mapping, and BCrypt encryption.
High-throughput e-commerce checkout and inventory API with Redis multi-layer caching, JPA optimistic locking to prevent double-checkout race conditions, and composite index tuning cutting latency by 65%.
Resilient financial transaction handler processing checkout sessions and asynchronous webhook events with HMAC-SHA256 signature verification, idempotency keys, and automated order state reconciliation.
Let’s build something impactful together — whether it’s high-throughput microservices, robust API architectures, or optimizing your database infrastructure.
Always excited to discuss microservices design, backend optimizations, and engineering opportunities.
