About Me

I am a Fullstack Software Engineer specializing in the development of robust SaaS platforms and automated business solutions. My expertise lies in building high-performance applications using Next.js 16 and the Supabase ecosystem, focusing on security, scalability, and complex third-party integrations.

From architecting multi-tenant VoIP control panels and automated rental management systems to engineering content-driven e-commerce engines, I bridge the gap between complex backend logic and premium user experiences. I thrive on solving integration challenges involving Stripe, Telephony (Asterisk), and Cloud Infrastructure.
