As a freelance Full Stack Developer, I build production features with React, TypeScript, and Node.js/Express, including polished, responsive, accessible interfaces.
I design REST and GraphQL APIs and work with relational and NoSQL databases, including PostgreSQL, MySQL, MongoDB, and Redis. I also implement authentication and authorization with JWT and OAuth2.
I built a small RAG-based chatbot that answers natural-language questions about technical equipment data, reviewing and validating AI-generated output before production. I use Claude Code and OpenCode CLIs, prompt engineering, and agentic AI workflows in my daily development work.
I test with Jest and Playwright, and deploy using Docker, GitHub Actions, and AWS or GCP. I collaborate with clients and cross-functional teams on requirements, architecture, and feature priorities in Scrum or Kanban workflows.
