Nikolas Sapalidis

I build custom software — websites, apps, AI systems — from scratch.

I started where most teenagers start: deep in the self-improvement rabbit hole. That led to trading and crypto, then running a Google Ads agency, then trying to sell digital products — and getting nowhere. Didn't make a cent from any of it.

Then I learned to code. Got my first paying client in February 2026 and realized it was actually working. Since then I've built across the full stack — websites, web apps, iOS apps, AI automations, custom pipelines, admin dashboards, internal tools. No templates, no page builders. Everything custom.

Alongside client work I build products. First was Helpmarq — a feedback marketplace for structured, expert feedback on real projects. Since then: Padel Up (iOS AI padel coach), MarketMyApp, Creator Roast, Branch AI (500+ npm downloads), NeuroPulse, and more. I also work at AutomateSphere AI building custom AI automation for businesses.

"No existing brief. Needed something premium without feeling generic. Four days later: live, custom, exactly what I asked for."

— Sean Lee, client

Since April 2026 I've been on Claude Code Max. It changed how I work. I run a homelab (self-hosted Supabase + n8n), ship multiple products in parallel, and build client work on the side. I write about the patterns that actually work — not the hype.

Currently

  • → Padel Up — in TestFlight review
  • → Noctiq — building (iOS sleep app)
  • → MarketMyApp — deploying
  • → AutomateSphere AI — client automations
  • → Client dev work — web, iOS, automations

How it works

  1. 1. Blueprint call — 30 min, you describe the problem
  2. 2. I send a scoped proposal within 24 hours
  3. 3. We build — Figma first, code after approval

Projects typically start at €800.

Taking 1–2 clients this month — slots fill fast.
