Lagos Ferry Map

The backend and data pipeline behind Lagos's first GTFS-compliant ferry dataset, submitted to Google Maps, OpenStreetMap and the Mobility Database. A Node/Express/Drizzle API on PostgreSQL powers public-facing crowdsourced submission forms for jetties and routes. A parallel Python toolchain, containerised with Docker on Cloud Run, publishes the GTFS feed, syncs route geometry from OSM/GeoJSON sources, and runs automated data-quality checks against the live database.

Sports Analytics Automation Pipeline

Built for a client, in production since June 2026. A production data pipeline that automates a full sports-analytics workflow. It scrapes live stats from five bot-protected sources, joins them with fuzzy name-matching, and runs a 150-point scoring model, writing ranked results back to Google Sheets. A non-technical client triggers the whole run from a spreadsheet button, turning a multi-hour daily process into a 5-minute one-click run. Click through to request a live demo.

Sports Bet Automation

Reverse-engineered an undocumented REST API to place single and combo bets programmatically on bc.game. Implemented JWT auth, input validation, and robust error handling, reducing manual execution to a single function call.

Exchange Rate Telegram Bot

A live Telegram bot that fetches currency exchange rates on demand and sends a daily rate broadcast via an in-process scheduler. Storage swaps automatically between PostgreSQL in production and a local JSON file in development, behind one shared interface.

~/about

Hey, I'm Fisayo, a self-taught backend developer specializing in Python, data engineering, and process automation. I hold a B.Sc. in Anatomy I've never used.

I care about building systems that work, that people actually appreciate, and that are useful to at least one person.

When I'm not coding or working, I'm probably watching a movie. Running is my midlife-crisis hobby. I'm also deep into chess, and my current rating, pulled live from the chess.com API, is …. I'd call myself nonconforming, and I love doing things just for the plot.

If you're working on something interesting: civic tech, history, financial literacy, or anything that'll make an impact no matter how tiny, I'd love to volunteer.
