What I'm looking for

I’m looking for a backend/microservices role where I can build secure, scalable APIs and multi-tenant systems with Java/Spring, work with Kafka and Kubernetes, and grow by shipping production-grade features.

I’m a Software Engineer at Kochartech building backend features for an enterprise SaaS platform with 4 product modules, supporting 10,000+ devices across 5+ international deployments.

I migrated a core Java web application from Java 8 to Java 21 across production deployments, designed a secure token authentication system (SecureRandom → SHA-256 → constant-time comparison), and built a multi-tenant policy enforcement engine using JSONB configurations.

I also constructed billing and risk enforcement from scratch, developed and optimized 8+ integration APIs for third-party device management protocols, resolved production outages by fixing SSL/TLS certificate validation misconfiguration, and mentored a junior developer intern on Java and Spring Boot architecture.
