Products people log in to every day.
Tell me about your projectA web app is more than pages: it has users, accounts, data that changes and a state for every case. As a product designer and product engineer, I design and build SaaS products, dashboards, client portals and internal tools end to end, designing the flows straight in the product as I build it.
I write it myself in Next.js, React and TypeScript, with Supabase for the database, authentication and storage, deployed on Vercel. When it helps, I add AI that does a real job in the product: search over your data, summaries, assistants or automations, built with limits and checks.

Questions about this service
A focused first version usually takes 6 to 12 weeks. We decide together what goes in and what waits, so it launches with what users need first.
Together they cover a whole product with few moving parts: pages that load fast, a Postgres database with authentication and access rules, and storage, all on services that scale with you. If you already have a backend or an API, I build on top of it.
Where it saves someone a repetitive task: finding information, summarizing, filling forms or moving data between tools. We look for those tasks first and skip the ones where it doesn't help.
You do. The code lives in your repository and the services run on your accounts from day one.
