Sobre mí
I build the internal systems businesses actually run on, the ones that replace paper, spreadsheets and WhatsApp threads.
Recent work: an operations platform tracing ocean-bound plastic through a supply chain that ran on paper; an append-only stock ledger for an online bike-parts seller; a white-label POS for cafes and restaurants; and a logistics PWA for a courier company, built end to end as sole developer.
I also ship native iOS and macOS software: Cutling, a clipboard manager for iPhone, iPad and Mac.

Prevented Ocean Plastic
Jan 2025 - Present • 1 yr 7 mos
Building the operations platform that is replacing paper across an ocean-bound plastic supply chain. Five roles, each with a purpose-built view: field admins log intake with photos and GPS, office admins verify arrivals and issue receipts, production leaders record bales and flakes output, lab staff score QC samples, and suppliers track deliveries and impact. Every entry carries a full audit trail with identity, timestamp, GPS and field-level diffs. Reports export to Excel, Sheets and PDF, and traceability QR scanning feeds downstream processors. Built in React Native and TypeScript on Expo and Supabase.
Freelance Software Developer
Eralink Indonesia
Sep 2025 - Apr 2026 • 7 mos
Built a travel-itinerary web app for an Eralink Indonesia client whose team was drafting customer itineraries by hand. Consultants build an itinerary in a form-based editor with a live PDF preview, then export a customer-ready document with airline logos and cover images. Drafts sit in a shared team library, and managers can view and edit everything through role-based access. React 19, TypeScript, Vite, Tailwind v4 and shadcn/ui on the front, react-pdf/renderer for document generation, Express.js and MySQL behind it.
