    I help startups build and improve SaaS, marketplace, and AI-powered web applications using React, Next.js, Node.js, and modern product-focused technologies. I’ve worked with founders and product teams on production systems that go far beyond basic UI implementation — including scalable frontend architecture, realtime features, payments, dashboards, API integrations, and long-term product maintainability.

I work across both frontend and backend development, with strong experience in: • SaaS platforms and internal dashboards • Marketplace and subscription-based applications • AI integrations and workflow automation • Realtime systems and WebSocket features • Stripe payments and third-party API integrations • Responsive, production-ready UI implementation • Performance optimization and maintainable architecture Core stack: * React / Next.js / TypeScript * Node.js / Express / PostgreSQL * Tailwind CSS * Supabase / Firebase * Stripe / OpenAI APIs * Docker / DigitalOcean / Vercel Clients usually work with me because I can: * Contribute beyond implementation * Communicate clearly and reliably * Work independently with minimal supervision * Balance fast iteration with maintainable code * Think about scalability and long-term product quality I’m comfortable joining existing products, improving unstable systems, building new features, or helping shape MVPs from the ground up. If you’re building a SaaS or product-focused platform and need a reliable engineer who understands both technical execution and product thinking, feel free to reach out. less
