Full Stack Engineer

Full-Stack Web & App Development Services

I’m a Senior Software Engineer who builds and maintains production web applications from the first architecture decisions through deployment and ongoing development. I work across frontend, backend, databases, APIs, integrations, AI features, authentication, payments, and cloud deployment. My main stack is React, Next.js, TypeScript, Node.js and PostgreSQL, with experience using Supabase, Prisma, Redis, Docker and Vercel. I’ve built and worked on SaaS products, AI automation systems, payment operations software and e-commerce platforms. Recent work includes AutoSetter, an AI SaaS platform for automated customer conversations and workflows, and CayPal, a payment operations platform connecting QuickBooks workflows with vendor payments, approvals and bank file generation. I’m comfortable taking an incomplete idea, turning it into a practical technical plan, building the system, integrating the required services, deploying it and fixing what happens after launch. I also use AI coding tools such as Claude Code, Cursor and Gemini as part of my development workflow. I use them to move faster while keeping architecture, security, testing and code quality under my control. I’m available for new products, existing application development, API integrations, AI features, SaaS development, debugging and technical consulting.
