$whoami

I build backend systems that scale, perform, and evolve — without breaking.

9+ years of experience building scalable backend systems, distributed architectures, and cloud-native platforms using Java, Spring Boot, Kafka, Python, FastAPI, and AWS.

I specialize in designing resilient, high-throughput systems with a strong focus on scalability, performance, and clean architecture.

Recently exploring GenAI, RAG, LLMs, and MCP — building intelligent applications that connect AI with real-world systems using Python FastAPI for high-performance API development and AI model serving.
