Building high-performance applications is easy; making them secure and scalable is where most projects fail. As a Full-Stack Engineer with a PhD in Biomedical Engineering, I bring a level of scientific rigor to software development that goes beyond simple coding. I specialize in the Next.js, Expo, and Supabase ecosystem, building robust SaaS and mobile platforms that prioritize clean architecture and data integrity. 🛡️ Specialized Service: AI Code Security & Logic Audits With the rise of AI-generated code, many applications are built with hidden vulnerabilities - insecure Row-Level Security (RLS) policies, exposed API keys, and inefficient database schemas. I provide comprehensive audits to transform AI-assisted prototypes into production-ready, hardened applications. Supabase Hardening: Auditing RLS policies and Edge Functions to prevent data leaks. Architectural Recovery: Refactoring "spaghetti" AI code into maintainable, modular systems. Logic Verification: Identifying edge-case failures in complex state management and auth flows. 🚀 Technical Expertise Frontend: Next.js (App Router), React, TypeScript, TailwindCSS, Solid.js. Mobile: Expo & React Native for cross-platform iOS/Android deployment. Backend & Infrastructure: Supabase (PostgreSQL, Auth, Real-time), Node.js, Python (FastAPI/Flask). Payments & Scaling: Full integration of Stripe and RevenueCat for global subscription models. 💡 Proven Track Record From developing a browser-based video editing suite to architecting real-time messaging platforms with complex permission hierarchies, I have a history of delivering technically demanding projects. My background in engineering means I treat your app’s logic with the same precision required for medical-grade hardware. Whether you're building a new MVP or need a security audit on an existing codebase, I ensure your application is built on a rock-solid foundation.
