Custom Web Application Development
For businesses that have outgrown templates and no-code and need software that fits how they actually work.
Who this is for
- Operators running the business on spreadsheets, WhatsApp and manual steps.
- Founders who need a real admin panel, dashboard or customer portal — not another template.
- Teams with an existing app that needs new features, integrations or a rebuild on solid foundations.
Problems it solves
- Data lives in scattered spreadsheets with no single source of truth.
- Work that should be automated is still done by hand every day.
- An off-the-shelf tool almost fits, but the last 20% is where the business actually lives.
What I build
- Dashboards and internal tools with real roles, permissions and audit trails.
- Customer & staff portals with authentication and row-level security.
- Admin panels and CMS so non-technical staff own their own content.
- API integrations between the tools you already use.
- Edge-native sites on Cloudflare (Workers, D1, KV) that stay fast and cheap.
Technologies
- Next.js
- React
- Vue 3
- TypeScript
- Laravel
- Supabase / PostgreSQL
- Cloudflare Workers
- Astro
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.
