Former Construction Engineer turned AI Research Engineer
I enjoy designing and refining AI pipelines — whether it's building RAG systems, orchestrating AI agents, or optimizing end-to-end workflows for production.
Currently leading Research Engineering at Braincrew, building production AI systems end-to-end.
Previously led the SoundMind AI Ecosystem (RAG Pipeline optimization, Admin Console, B2B SaaS Platform) at Soundmind (2025.07 ~ 2026.03).

WIGTN FLAKE — A purpose-driven local intelligence platform. Users pick what they want to do — open a cafe, run targeted rental marketing, place outdoor ads, invest in real estate — and an AI expert panel cross-reads four datasets (real estate, foot traffic, card sales, telecom contracts) to recommend the best neighborhoods, surface anomaly signals before they show up in headlines, and project six-month trends. Built on a hybrid Snowflake Cortex × GPT-4o orchestration that lets the analysis read like a conversation between domain experts rather than a dashboard.
