What I'm looking for

I'm looking to build reliable backend, AI, or LLM systems where I can own core mechanics, strengthen production reliability, and keep learning infrastructure by working hands-on with real systems.

I built the FastAPI, data, and deterministic scoring layers for Amparito at Scala Labs, a conversational insurance advisor where every recommendation is auditable and no numbers are hallucinated by design.

I delivered HotelIQ solo for a live hospitality client, replacing 250 minutes of manual work with a five-minute automated run. I designed reliability into the system with exponential-backoff retries, idempotency, and distributed concurrency locks.

I'm also building codingAnt from scratch on the raw Anthropic API, implementing tool-calling loops, async failure handling, SQLite observability, and pytest-based evaluation before relying on frameworks.
