I build SaaS products and Chrome extensions using Next.js, Supabase, TypeScript, and React. Most of the products I work on start as MVPs but are expected to grow, so I think about authentication, billing, permissions, and maintainability from the beginning. I usually work with founders who already have a product idea and need someone who can take ownership of the technical side of implementation. That might mean building a system from scratch, improving an existing codebase, or cleaning up a prototype that has become difficult to maintain. Some of the work I’ve done recently: - Building full-stack SaaS applications with authentication, file uploads, Stripe billing, dashboards, and AI-powered functionality - Developing Chrome extensions connected to SaaS backends through secure authentication, background processing, and data synchronization - Refactoring large Next.js applications to improve SEO, SSR, caching strategies, and long-term maintainability - Designing Supabase systems involving Auth, PostgreSQL, Row Level Security (RLS), Storage, and server-side logic - Improving search and filtering performance through query optimization and server-side rendering - Integrating third-party services such as Stripe, OpenAI, and Podio into existing products Technologies I work with regularly include Next.js, React, TypeScript, Supabase, PostgreSQL, Stripe, Vercel, OpenAI API, Chrome Extensions (Manifest V3), REST APIs, serverless functions, SSR, caching strategies, and role-based access systems. If you're ready to hand off the technical heavy lifting and focus on growth, drop me a message and let's map out your roadmap.
