Sil Van Hunnik

I build software products from the initial idea to a working, paid application — independently, quickly, and without unnecessary layers.

Lately, I have built, among other things:

QICK! — a B2B work-operations platform for Dutch SMEs (construction, hospitality, security, cleaning): from clients and planning to hours, work orders, and invoicing.

BalanceBuild — a SaaS app for nutrition, training, and skincare, including subscriptions and AI-assisted advice.

I built both projects end-to-end: database architecture, payment integration, user management, and a production-ready interface.

What I do:

Front-end: React, TypeScript, Tailwind

Back-end & database: Supabase (Postgres, Auth, Row-Level Security, Edge Functions)

Payments: Stripe (subscriptions, checkout, webhooks)

Deployment & hosting: Vercel

AI integration: connections with the Anthropic/Claude API, use of AI tools (Claude, ChatGPT, Cursor/Codex) to develop faster and more structured

PWAs, multi-language apps (NL/EN etc.), roles & permissions, exports

How I work:

I work in a structured way: first a clear plan and scope, then build in manageable steps, no scope creep and no half demos — everything I deliver truly works end-to-end. I communicate directly about what is and isn't feasible within a timeline or budget.

I help companies and entrepreneurs with:

Building an MVP from scratch

Further developing or rebuilding an existing product

Setting up Supabase/Stripe integrations

SaaS architecture and database design
