Python, FastAPI, PostgreSQL, Gemini, Tesseract OCR, Streamlit, Docker

• Engineered an end-to-end ETL pipeline that ingests unstructured PDFs and images and turns them into structured, queryable records.
• Integrated the Gemini LLM with Tesseract OCR to automate field extraction, cutting manual data entry out of the loop.
• Designed a multi-tenant PostgreSQL architecture with isolated per-user storage behind secured REST endpoints.
• Built a Streamlit monitoring dashboard surfacing real-time pipeline metrics; the whole stack ships as one Docker Compose file.

React, Node.js, Express, MongoDB, Socket.IO, Docker, GitHub Actions

• Built a household management platform covering shared expenses, chores and communication, deployed and running in production.
• Implemented a debt graph that recalculates and redistributes outstanding balances when a member leaves, instead of dropping them.
• Added real-time house chat, polls and a gamified chore leaderboard over Socket.IO.
• Automated build, test and deployment through a GitHub Actions CI pipeline.

Node.js, Socket.IO, React, MongoDB, Docker, GitHub Actions

• Built a room-based WebSocket messaging platform with secure six-character room codes and message persistence in MongoDB Atlas.
• Server-side room validation rejects connections to dead rooms before they open, eliminating ghost sessions.
• Containerised with Docker Compose and wired into CI for repeatable builds and deploys.

React, Node.js, Express, PostgreSQL, Prisma, Supabase, JWT

• Developed a full-stack expense tracker with JWT and bcrypt authentication guarding protected routes on both client and server.
• Modelled transactions in PostgreSQL via Prisma with multi-currency support and localized formatting.
• Visualised category spending with interactive Recharts dashboards.
