  • Solid TypeScript expertise
  • Familiarity with Tailwind CSS
  • Strong Node.js + TypeScript experience
  • Proficiency in NestJS, Express, or Fastify

  • Understanding of database design and ORMs (MySQL/PostgreSQL)
  • Ability to read and work with existing PHP/Symfony code
  • Willingness to refactor PHP into TypeScript
  • Bonus: experience with LangGraphJS or AI agent development (LangChain ecosystem)
Benefits
  • Real ownership: your ideas and contributions directly shape the product
  • Small team: have direct impact with fast decisions and limited bureaucracy
  • Modern stack: work with cutting-edge tools (Next.js 15, LangGraphJS, AI agents)
  • VSOP (virtual stock option) plan: share in the company’s success
  • Modern equipment: top-tier gear, including a MacBook Pro
