Marketplaces, inventory systems, and post-sale platforms — designed, built, and shipped to production. Node, React, and PostgreSQL, from schema to the last pixel.
I'm Derek — a full-stack developer who turns business problems into polished, production software.
Each one is live software with real users — payments, inventory, and onboarding that had to work, not just demo well.
A two-sided marketplace connecting video creators with freelance editors — handling discovery, contracts, PIX escrow payments, and trust between strangers, end to end.
inova stok — inventory consoleA single-tenant inventory system for a car dealership where every stock movement is an event — fully auditable, reversible, and running in production.
A post-sale platform built for a paying real-estate client — onboarding buyers and guiding them through everything that happens after the purchase is signed.
nic crochet — storefrontA handmade-crochet storefront for an independent maker — a product catalog, custom-order requests, and a calm shopping experience built to turn browsers into buyers.
I build full-stack web applications end to end — comfortable in a PostgreSQL schema, a TypeScript service, and a React component in the same afternoon.
I care about software that actually ships: clear data models, honest interfaces, and code the next developer can read. The projects here are live products with real users — not demos.
Open to junior and internship developer roles, and to freelance projects. The fastest way to reach me is email — I usually reply within a day.
