Retrieval, extraction, classification and evaluation pipelines that survive contact with real data. RAG, fine-tuning (LoRA / QLoRA / PEFT), DSPy prompt optimization, LLM-as-judge evals, and the MLOps glue to ship them.

Consumer GPU + Ollama + vLLM + a single gateway + tracing. Nothing leaves the box. Every model earns its spot with a reproducible, checksummed eval bundle or it doesn't ship.

Formerly a Senior Data Scientist at the UN Office on Drugs and Crime. Text analytics and entity extraction for economic crime, corruption and regulatory work.

Frame data, hitboxes, parries and cancels recreated in pure Python, plus a Gymnasium RL environment for Street Fighter 3rd Strike running on stock MAME. Because the lab work never ends.

Local, private prompt optimization with DSPy + Ollama. Paste a rough prompt, get a rewrite, a score and a diff. Add a small dataset and it measures candidates on held-out examples and evolves instructions from written feedback with GEPA, showing the lineage of every edit. No API keys, nothing leaves your machine.

Does an assistant's earlier refusal make it more likely to refuse the next request? A controlled study of refusal hysteresis: 65 borderline prompts, byte-identical final turn, multiple conversation set-ups, a blind LLM judge, bootstrap CIs. Result of record reproduces offline from a fresh clone.

Retrieval-Augmented Generation from notebook experiments to a deployable FastAPI + TypeScript document-AI app on Azure OpenAI and AI Search.

LangChain LlamaIndex FastAPI Azure TypeScript

A local LLM workstation and on-demand server for one Ubuntu desktop with one consumer GPU. Ollama for chat, vLLM for batch, Bifrost as the single gateway, Phoenix tracing everything. Cloud fallback: never. Every claim exercised end-to-end on real hardware and written up in ADRs.

Because life's too short for a boring terminal. Zsh configs, aliases, theming and the scripts I actually reach for every day.

Zsh CLI dotfiles

From frame data to fireballs. A love letter to Street Fighter III: 3rd Strike, written in pure Python: parries, cancels, hitboxes, frame data and that sweet self-KO energy.

Python Pygame Frame data

A Gymnasium RL environment for 3rd Strike on stock MAME. Bring your own ROM.

Gymnasium MAME RL

Detecting drug seizure information in open-source news with Named Entity Recognition. Unstructured articles in, structured intelligence out.

spaCy Transformers NER

Mapping the crypto risk landscape: a spaCy text classifier that flags scam and fraud discussion on Twitter. Annotated in Prodigy with active learning, weak-labelled with Snorkel, tuned with W&B sweeps.

spaCy Prodigy Snorkel Weights & Biases

A Scrapy crawler that collects open-source news worldwide for downstream analysis. Paginates politely, slow-rolls to avoid bans, exports structured data instead of chaos.
