Zelt is a unified HRIS built for mid-market companies in Europe. The tech stack—React, TypeScript, Node.js, PostgreSQL, AWS infrastructure—is standard for a fintech-adjacent product handling sensitive employee data, but the project mix reveals a company in scaling mode: active work spans product design systems, AI-powered support automation, and sales pipeline expansion, all while contending with growth friction across UX and support efficiency.
