SaaS & Product Development
From an idea (or a stalled MVP) to a product real users can sign up for and pay for.
Who this is for
- Solo founders and small teams building their first SaaS.
- Non-technical founders who need a technical owner for the build.
- Products with a working prototype that needs to become production-grade.
Problems it solves
- You have the idea and the users but no one to own the engineering.
- A prototype exists but it cannot handle real accounts, billing or scale.
- Payments, subscriptions and usage limits are hard to get right and easy to get wrong.
What I build
- Multi-tenant architecture with authentication and row-level security.
- Billing, subscriptions and metered usage wired to real payment providers.
- Admin dashboards, analytics and the operator tooling a SaaS needs day two.
- An OpenAI-compatible AI layer when the product is AI-native (I built my own — Vensix).
Technologies
- Next.js
- React
- TypeScript
- Supabase / PostgreSQL
- Cloudflare Workers
- Stripe / QRIS / Midtrans
- Zod
How it works
- Intro call (free, 20 min). You describe the product and the problem; I tell you honestly whether I’m the right fit.
- Scoped proposal. Fixed scope, fixed price, written acceptance criteria — no open-ended hourly billing.
- The work. Weekly demos on a preview URL, a written handover, and a walkthrough call at the end.
