What I'm looking for

I’m looking for a role where I can build end-to-end products with React and FastAPI, deliver scalable async APIs, and ship production RAG/LLM features on AWS—while owning performance, reliability, and measurable impact.

I’m a Full Stack Engineer with 6+ years delivering end-to-end web applications across React.js, FastAPI, and Python. I focus on scalable async microservices, RESTful APIs, and production AI systems that users can trust in real environments.

In my work at CitiusTech, I architect scalable RESTful APIs with FastAPI and SQLAlchemy, migrating monolithic services to async microservices and cutting average API response time by 35%. I built full-stack shipment scheduling with React.js, FastAPI ingestion, Celery workers, and AWS S3/SQS/Lambda-style workflows—plus reliable duplicate detection and robust row-level retry logic.

I also develop LLM-powered solutions using LangChain (LangGraph), RAG pipelines, pgvector/Vector Embeddings, and OpenAI/Claude, improving accuracy by 60% over keyword search. I re-architect React.js performance with memoization and code-splitting for a 40% reduction in initial load time, while reducing ticket resolution time by 20% and accelerating delivery timelines by 50% earlier in my career.
