At TAD, I delivered backend and full-stack features across 10+ client projects, taking products from early prototypes to mature platforms. I refactored a legacy Python backend with query optimization, caching, and asynchronous processing, reducing average response time from ~5s to ~0.1s.
I also optimized a major client's cloud infrastructure by right-sizing compute and consolidating services, cutting costs by ~70% while preserving performance and uptime. For other TAD projects, I built a café people-traffic analytics system and developed an AI-powered real-time voice chatbot for an exhibition.
At Conduit.app, I developed backend services and data processing pipelines for a B2B analytics platform covering sales, marketing, and ad performance. I redesigned its CI/CD pipeline, reducing linting and test time from 3–5 minutes to ~10 seconds, and optimized PostgreSQL reporting queries.
At WONO, I designed and implemented backend architecture from scratch for a P2P freelance and trading platform. I developed its deals, disputes, escrow-like flows, and balances, built real-time chat, and integrated blockchain smart contracts for P2P transactions.
