As a Senior Full-Stack Engineer for a private technology firm under NDA, I architect and deploy highly scalable, production-ready web applications and SaaS platforms. Core Responsibilities & Achievements: SaaS Architecture: Engineered complex, multi-tenant SaaS environments using Next.js, React, and strictly typed TypeScript. Backend & Security: Designed robust PostgreSQL database schemas via Supabase, implementing strict Row-Level Security (RLS) to isolate and protect sensitive user data. Commercial Integrations: Built automated, secure payment infrastructures using Stripe and Paddle webhooks for high-volume subscription billing. Performance Optimization: Led frontend UI/UX development using Tailwind CSS, consistently achieving 100/100 Google Lighthouse scores through Server-Side Rendering (SSR) and edge-network deployments. Codebase Management: Maintained pristine, modular, and fully documented GitHub repositories for seamless CI/CD deployments to Vercel and AWS.
