Project description

  • development of the user interface for an AI-first startup building an agentic B2B SaaS platform that helps small businesses manage marketing, sales, administration, communication, and daily processes
  • collaboration on a product in the ramp-up phase towards live operation, aiming to function as a premium "company operating system" built on AI agents and LLMs
  • design and implementation of the frontend part for LLM UIs, chat interfaces, streamed responses, visualization of agent steps, and tool-calls
  • creation of human-in-the-loop approval flows in the "propose → draft → execute" logic

  • development of a production application in TypeScript, React, Next.js App Router, and Tailwind CSS
  • connecting the frontend to Node.js and Azure backend via REST API, GraphQL, webhooks, and OAuth2
  • integration of calendars, email, chat, CRM, and payment systems with an emphasis on reliability, retries, idempotence, and error handling
  • close collaboration with a backend developer in a small two-person product team with a high degree of autonomy and responsibility for the outcome
  • rapid prototyping, refactoring, and development using modern AI tools like Cursor, Claude Code, GitHub Copilot, Windsurf, or v0
  • possibility of long-term cooperation after an initial approximately two-week paid trial on a real product module
  • cooperation in a fully remote mode with the possibility of occasional onsite meetings in Prague or Lisbon
