White-Label Development Partner
I build the sites, booking systems, and internal tools your agency doesn't have bandwidth for — under your name, on your terms. 13 systems are live in production for real clients right now, not portfolio mockups. If you need a developer you can hand a scope to and forget about, this is that.
What I take off your plate
- Full website builds — Next.js / React, from a Figma file or a scope doc.
- Custom systems: booking, CRM, internal tools that off-the-shelf software doesn't fit.
- Overflow capacity for client work you've sold but don't have hands for.
- Ongoing maintenance and bug fixes on existing codebases, yours or a client's.
- Fully white-label — no branding, no signature in the code, you own the client relationship.
How it works
You send the scope. I quote and give a timeline within 48 hours. If it's a fit, we work under NDA if you want one, and I invoice you — either per project or as a standing retainer.
- One point of contact: me, directly. No account manager, no handoff between teams.
- You stay the client's only contact — I don't reach out to them, don't get credited, don't exist to them.
- Async-friendly. CET timezone, fluent English, fast replies.
Why a solo developer, not an agency
- 13 systems in daily production use for paying clients — proof, not a portfolio of demos.
- Stack: Next.js, React, TypeScript, Postgres (Supabase/Neon), n8n for automation and integrations.
- Based in Niš, Serbia — EU-adjacent rates, EU timezone, no offshore lag.
- You're not routed through tiers of project managers. The person quoting the work is the person writing the code.

Questions agencies ask
Is this strictly white-label / NDA work?
Yes. No public credit or portfolio mention unless you say otherwise. Happy to sign your NDA or use mine.
What's the stack?
Next.js, React, TypeScript, Postgres (Supabase or Neon), Zod, n8n for workflow automation. I can also work inside an existing codebase in a stack you already have, if it's reasonably close to this one.
How fast can you start?
Quote and timeline within 48 hours of getting a scope. Start date depends on size — usually within a week.
One-off builds only, or ongoing work too?
Both. Single projects, or a standing retainer if you have recurring overflow.
Timezone and communication?
CET (Serbia). Fluent English, async-friendly, direct replies — no support ticket layer.
