About this gig

Stop settling for static templates. I build dynamic, logic-heavy web applications designed for speed, security, and scalability. Specializing in the Next.js, Node.js, and Supabase stack, I help clients transform sophisticated business requirements into production-ready software.

What I Specialize In:

  • Real-Time Engines: Custom logic for gaming, betting (Roulette/Crash), and live dashboards using JavaScript logic rather than heavy assets.
  • Scalable Backends: Advanced Supabase integration, real-time data replication, and optimized PostgreSQL schemas.
  • Data Automation: Custom web scrapers and structured data pipelines to fuel your app with live market or financial data.
  • Security-First Coding: Proactive protection against SQLi and XSS, backed by experience in vulnerability scanning.
  • Full-Stack Deployment: End-to-end management from Git workflow to Vercel production and DNS configuration.

Whether you need a "no-login" landing page with a robust admin side or a complex real-time platform with automated payouts, I deliver clean, documented code that performs.

Lets build a system that works for you. Message me to get started!
