I've delivered seven paid web applications for private clients, with five still in use through my ownership of development, deployment, maintenance, and post-production support. My work spans TypeScript, Next.js, React, PostgreSQL, APIs, payment flows, admin tools, and operational dashboards.
I built three financial systems now running in production, processing 2,806 transactions in 25 days, and created an ERP that centralized six branches and reduced daily reconciliation from about 60 minutes to near automatic. I also delivered a Stripe-based tattoo raffle with atomic reservations, idempotent webhooks, transactional email, and admin tooling.
