About me

Full-Stack Developer for AI-ready B2B SaaS, marketplaces & internal tools (Node.js/NestJS, React/Next.js, n8n/Node-RED etc). Best fit for funded teams planning multi-week product work, not small fixes.

I’m a Senior Full-Stack Developer focused on B2B SaaS, marketplaces, internal tools and AI-powered platforms.I design, build and scale full-stack web applications as a full-stack JavaScript/TypeScript developer using Node.js, NestJS, React, Next.js, Vue, Nuxt.js, Laravel/PHP, PostgreSQL, MySQL, MongoDB, Redis and automation tools like n8n and Node-RED. I work both as a Full-Stack Developer and Back-End Developer on SaaS platforms, multi-tenant products, marketplaces, booking systems and internal dashboards - from first MVP to production and long-term support.
