Hello, I am Giran Oh.
I am a Data & AI Engineer interested in turning data and AI into decisions that operate inside real products.
I look beyond a single feature.
At loop-ad, I worked on behavior-driven audience selection, reproducible audience snapshots, data contracts, evaluation, and lifecycle boundaries. I value systems whose decisions can be explained, tested, and operated.
Technical experience
Products and APIs
Python, FastAPI, REST APIs, domain modeling
Data and contracts
PostgreSQL, ClickHouse, DTOs, schema verification
Operations
Docker, Cloudflare, and AWS deployment experience
Frontend
React, TypeScript, and user-flow verification

I continue to document projects and writing around evidence that can be shared publicly.
