Capabilities

What I build — and the technology behind it

What I can design and build end to end — each one backed by shipped products, open-source libraries, or production systems.

Product Engineering

Complete products end to end — execution engines, visual editors, plugin systems, and the architecture that ties them together.

AI Platforms

LLM, RAG, and agent systems designed for production: evaluation, cost, and reliability.

Machine Learning Infrastructure

Training, deployment, monitoring, and AutoML — the domain of my open-source libraries.

Data Engineering

Pipelines, streaming, and data platforms that keep complex systems fed and reliable.

Cloud Architecture

Containerized platforms, CI/CD, and infrastructure as code on Azure.

Python Ecosystem

Libraries published on PyPI and conda-forge, with public documentation and CI.

Technology
