What I'm looking for

I'm building toward low-latency systems, quantitative research infrastructure, concurrency, and performance engineering.

At Eyes4Research, I architected a FastAPI platform that turns survey datasets into interactive AI agents, using LLM-driven schema inference to map and validate uploaded files without manual configuration. I also built a multi-provider AI gateway and a WebSocket voice layer for real-time audio.

I designed background processing for survey ingestion and embedding generation, then added Qdrant semantic search for context-aware retrieval. I also handled deployment and automated delivery, including a GitHub Actions pipeline that replaced manual deployments.

At QuestionPro, I engineered a modular NestJS backend with multi-tenant data isolation, role-based access, and a priority-based call queue designed to avoid race conditions. Across other projects, I built an ETL pipeline for European price data and contributed frontend features to the Local AI Community platform.
