I build and run backend systems where money moves. For 6 years I've worked on production Rails platforms for US companies. Today that's payments and subscriptions at TuneCore, a music distribution platform that has paid independent artists more than $5B. Before that it was Lucet, a behavioural health platform covering 15M lives, where I raised test coverage by 40%.

• 💳 Payments: multi-gateway billing across Adyen, PayPal, Braintree and PayU, plus renewals, webhooks and Avalara real-time tax
• 🧱 Backend: reliable APIs, background jobs, and keeping large legacy Rails codebases healthy
• 🤖 AI tooling: guardrails for coding agents and LLM pipelines, such as test-weakening detection and PII redaction
