Work with senior Python engineers.

Python engineers who write production code — not notebooks with tests.

Python is our workhorse for backends, data, and AI. We write it with type hints, proper packaging, and the same rigor we'd apply to Go or TypeScript — because once it's past the prototype stage, the sloppy-Python tax is real and expensive.

Why Sonnet Code for Python

The bar we hold ourselves to.

Typed and tested

mypy, pydantic, pytest — not optional. The Python we ship reads like a statically-typed codebase.

Data + AI fluent

From pandas pipelines to PyTorch training loops to Vertex AI deployments, we know the whole stack.

Packaging that doesn't hurt

uv, Poetry, Docker multi-stage builds — dependency management that doesn't ruin your week.

What we build with Python

Python work, shipped.

FastAPI backends

Typed, async Python APIs with OpenAPI generation, proper auth, and the observability to debug them in prod.

Data pipelines

Airflow / Prefect orchestration, pandas / Polars transforms, and pytest coverage you can actually trust.

ML systems

PyTorch training, ONNX deployment, feature stores, and evaluation harnesses that catch regressions.

LLM applications

LangChain and bare-metal OpenAI / Anthropic SDK work with retrieval, tool use, and proper caching.
