What I do for you

From messy data to working software

Clear, well-scoped work.

Make your data usable

Pull data from different sources and turn it into one clean, reliable dataset you can actually work with.

Collect data from the web

Automatically gather prices, product info, or listings spread across websites, delivered as a clean file.

Automate manual work

That repetitive task someone does by hand every week? I turn it into a script that runs itself.

Build the tool you need

A custom Python service, an API, or a small internal tool built around your specific process.

Put AI to work on a task

Custom AI-agent tools for a specific job, where the model makes the decisions and tested code does the reliable work.

MCP tools for AI agents

A set of MCP servers that give AI agents reliable access to real, messy data. All published on PyPI and listed in the official MCP registry. The idea throughout: the model decides what it wants, tested code does the actual reading, so values are never guessed.

PyPI · MCP registry

excel-agent-mcp

Lets an agent read real messy Excel files: multiple sheets, auto-detects the header row under title rows, forward-fills merged cells. pip install excel-agent-mcp

pdf-agent-mcp

Pulls text and tables out of PDFs (invoices, reports) as clean rows instead of a flattened blob. pip install pdf-agent-mcp

code pypi

agentic-csv-cleaner

Cleans messy CSVs where the LLM only picks which cleaning steps to run and tested code does the transforms. pip install agentic-csv-cleaner

code pypi

hyperliquid-price-mcp

Gives an agent live crypto prices and candles, so it can answer "what's BTC at right now?" instead of guessing from stale data. pip install hyperliquid-price-mcp

Other projects

Live demo

Real-Time Market-Data Platform

Real-time ingestion → storage → OHLCV aggregation → live dashboard, with analytics (volatility, anomaly detection). Idempotent, tested, Dockerized.

▶ live demo code

Product-Catalog Scraper

Dependency-light scraper: pagination, retry/backoff, polite rate-limiting, clean CSV output. Adaptable to any site.

code

ML Validation Pipeline

Honest out-of-sample validation (NumPy): walk-forward, permutation nulls, to check whether a result is real or just noise.

code

Tax Valuation Engine

Country-neutral core plus per-jurisdiction plugins, exact decimal math, swappable price source, tested. (Domain: crypto tax, NL box 3.)

About

Lab background, now in code

Before software, I spent six years in molecular diagnostics labs: sequencing, assay validation, and work under GMP. That's where I got careful with data: check it, reproduce it, don't trust a number you can't back up. I work in data and backend engineering now, and the lab background means I understand the domain as well as the code.
