ABOUT ME
Senior Python & AI Engineer
Senior Python & AI Engineer
Senior Python and AI engineer with 9 years of experience building production backends and AI products for US and European teams. I build LLM agents, RAG pipelines, FastAPI services and data systems, and I take over fragile or half-built systems and ship them in small, verifiable milestones.
Recent work: backend engineering on a US fiduciary-banking platform (AWS Cognito login migration, GraphQL APIs, ACH return processing, AI-assisted developer workflows with Claude Code); Skreen, an AI candidate-screening platform that runs multiple interviews in parallel through an LLM evaluation pipeline with human review; UnBotify AI, a humanized-text SaaS built end to end on FastAPI and React; and backend modules for GeoX AI, a property-risk platform covering about 160M US properties and used by Aon and Munich Re.
Top Rated Plus on Upwork with 100% Job Success and 2,000+ hours. Available now for 30+ hours a week, and happy to work US and European hours.
Skills: Python, FastAPI, Django, Flask, PostgreSQL, AWS, GraphQL, LLM agents, RAG, OpenAI and Claude APIs, React, Docker.

Wrote Dockerfile and docker-compose file for multiple projects and utilized their functionality to optimize the process. Like:
- If two services are running on the same image with the different commands then use instead of building two images just use the same image with the different command option.
- Write Dockerfile build steps in a way so that any changes to the code files don't make it re-install the library. This saves a lot of time while rebuilding the image.

This is a Django based project which allows complete management of Venues/Booking Hall/etc for both the Venue owner and the consumers. It allows users to search and book any venue via a mobile app. Users can select a date range and then select one of the available venues. Venue owners can be registered via Site Admin and then they can use their own Vendor Admin Panel where they can list their available venues and the products as well.
