Python engineering teams frustrated by 10-minute `pip`/`poetry` dependency resolution, slow Flake8/Black/isort pre-commit hooks, or untyped runtime `AttributeError` crashes frequently search to hire a freelance Python architect to modernize their stack with Astral `uv`, `ruff`, `mypy`/`pyright`, and `pytest`. I am Aldian Fazrihady, a Senior Freelance Python Programmer available via Upwork.
Core Python Developer Experience (DevEx) & Quality Capabilities
- 10x–100x Faster Dependency & Docker Builds with `uv`: Migrating legacy `requirements.txt`, `Pipenv`, or `Poetry` setups to deterministic `pyproject.toml` + `uv.lock` workspaces and multi-stage `uv sync --frozen` Dockerfiles.
- Sub-Second Linting & Formatting with `ruff`: Replacing Flake8, Black, isort, pyupgrade, and bandit with a single Rust-powered `ruff` configuration enforced in pre-commit and CI.
- Strict Static Typing (`mypy` / `pyright`) & Parallel `pytest-xdist`: Adding gradual or strict type annotations and fast transactional PostgreSQL test fixtures.
Frequently Asked Questions
How much faster are CI and Docker builds after switching from `pip`/`poetry` to `uv`?
In production Python repositories, switching to `uv` with BuildKit cache mounts routinely drops Docker image build times from 4–6 minutes down to 15–25 seconds.
