About Me
I am a Full Stack Software Engineer with 9+ years of experience building and scaling web systems. I founded and scaled my own multi-tenant SaaS to 10,000+ paying recurring users at 99.9% uptime — owning product, PHP/Laravel + MySQL engineering, and Linux/Cloudflare infrastructure in production as a one-person tech team. Today I deliver software for B2B clients: marketplaces, operations SaaS, dashboards, CRM automation, AI agents and security audits — mostly in TypeScript, React/Next.js and Node.js, with production work in .NET, PHP and Python.
