I’m a backend engineer with production experience building scalable microservices, REST APIs, and data pipelines using Node.js, Django, and FastAPI. At Oggangs Pvt. Ltd., I built and maintained authentication and business-logic REST APIs at scale, implemented asynchronous background job pipelines with Bull.js (Redis) to cut API latency, and integrated Elasticsearch to deliver sub-second retrieval across millions of documents.

I also built a Django microservice that acted as both a REST API and a scraping engine, feeding clean/normalized data into enrichment pipelines. My work extends to intelligent backend flows—structuring information from conversations using an LLM, applying hierarchy-matching logic, and auto-generating product records—alongside careful MongoDB schema design, indexing for high-write distributed workloads, and Dockerized microservices. In my projects, I’m currently architecting a microservices-based RAG platform with Express.js and FastAPI, deploying vector search with Qdrant and inference via the Groq API.
