Volodymyr K.

Vetted Developer in Ukraine (UTC+3)

Full-Stack Developer with 5+ years of experience building scalable web and mobile applications across SaaS, fintech, healthcare, and marketplace domains. I specialize in designing and delivering end-to-end features, from product requirements to production-ready systems. I have strong experience working with React, Next.js, and TypeScript on the frontend, and Node.js (NestJS/Express) on the backend. I regularly work with both SQL and NoSQL databases, including PostgreSQL and MongoDB, and build reliable APIs and integrations with third-party services. In my recent work, I’ve focused on building data-driven and AI-powered features, integrating external APIs, and optimizing system performance and scalability. I’ve also worked with Firebase and Supabase for real-time applications, authentication, and backend services. I’m comfortable working in fast-paced environments, taking ownership of features, and collaborating closely with product and engineering teams. My focus is on delivering clean, maintainable code and building systems that scale. Tech stack includes React, Next.js, TypeScript, Node.js, NestJS, PostgreSQL, MongoDB, Firebase, Supabase, AWS, and Docker. I also use AI-assisted development tools to improve speed and code quality.
