Product Engineer / Founding Engineer
Four years as the sole engineer behind WTB Market (opens in new tab): 1,700+ paying users, 50 storefronts, 150K+ deals completed. Now Engineer #1 at Subflare.
Three products I built end to end. Two have a live demo you can click through.
Sole engineer · Product ownership
Inventory and sales platform for a community of resellers: stock, sales, shipments and public storefronts in one place.
Used daily by 1,700+ paying users across Europe, with 150K+ deals completed through the network since November 2022 across 50 active storefronts.
Independent product · Built in 5 weeks
Personal finance dashboard replacing a Google Sheet, tracking cash, investments, recurring bills and resale inventory in one Postgres database.
Tracks 2,400+ transactions since March 2023, with balances, net worth and portfolio value all derived at read time. First complete version shipped in 5 weeks.
Client project · Operations automation
Internal dashboard for a Shopify business, managing operations and market-based pricing workflows refreshed daily.
Keeps 700+ products and 9,000+ variants in sync with real market data, refreshed daily without manual review.
Mostly as the only engineer: I design it, ship it and get the alert when it breaks.
I've reported 250+ bugs in other people's products. It changed how I build mine.
At WTB Market there was nobody to hand work to, so I own the whole path: data model, API, UI, deploys and monitoring. At Subflare I'm doing the same job on a production system I inherited.

Test Engineer I · Freelance
Progressed from tester to Test Lead and Test Engineer I across 7 projects for international brands, coordinating testers and Team Leads, and brought that testing discipline into product engineering.
