At CollegeDunia, I build and optimize production backend APIs with NestJS, MySQL, and Redis, cutting average latency from 800ms to under 100ms. I also integrated Elasticsearch search, built RBAC-enabled CMS tooling, and support AWS deployments, monitoring, and reliable asynchronous workflows.
Previously at Softapper, I developed RESTful Node.js and MongoDB services. I also build Python data pipelines and RAG systems, including automotive semantic retrieval using Qdrant and large-scale distributed web scraping and ETL workflows.
