You will get Next.js & Node.js Developer | SaaS Web Apps & Custom Platforms
Project details
I don't just build websites; I engineer scalable web applications.
Unlike freelancers who rely on generic templates, I build custom SaaS solutions and Dashboards tailored to your specific business logic using the modern JavaScript stack (Next.js, Node.js, and PostgreSQL).
Why work with me?
Real Experience: I recently engineered complex automation systems like "PriceWatch Pro", a real-time price tracking bot with cloud database integration.
Full Stack Power: I handle the entire lifecycle—from the database architecture (SQL) to the pixel-perfect Frontend (React/Tailwind).
Performance First: My apps are built on Next.js for lightning-fast loading speeds and SEO optimization.
Whether you need an MVP to launch your startup, a custom CRM, or a Data Dashboard, I deliver clean, secure, and maintainable code.
