πŸ‘‹ Hey! I’m Nirupom

I build high-performance distributed systems, AI-driven automation, and scalable backend platforms.

My work spans:

  • ⚑ Backend Engineering (Python/FastAPI, Java/Spring Boot, gRPC)
  • πŸ•ΈοΈ Distributed Systems (distributed key-value store, Kafka, consensus, replication, anti-entropy)
  • πŸ—ƒοΈ Databases (PostgreSQL, Redis, Neo4j, MongoDB)
  • 🧠 AI Systems & LLM Engineering (RAG, agents, embeddings)
  • ☁️ Cloud Infra + Observability (Docker, Prometheus, Grafana, AWS/GCP)

I am skilled at translating complex technical challenges into clean, reliable, and production-ready systems.
