Building production-grade backend systems using:

• Spring Boot & Spring Security
• RESTful API design
• Microservice architecture
• JWT-based authentication & RBAC
• Database design and optimization
• Redis caching
• Kafka-based asynchronous processing
• API documentation with Swagger/OpenAPI

I enjoy designing systems around:

Microservices → Kafka → Async Processing → Redis → Relational Databases

with a focus on reliability, scalability, and clean service boundaries.

Currently working on backend systems that combine traditional Java services with:

LLMs + RAG + Vector Search + STT/TTS + Kafka
