Develop frontend functionality using React when required. Help improve onboarding, automation, and operational workflows through technology. Participate directly in discussions with U.S.-based stakeholders. This role is approximately 70% backend and 30% frontend.

Experience building backend services using Spring Boot, Ktor, or similar frameworks. Solid React experience. Strong SQL and PostgreSQL knowledge. Experience integrating external APIs and third-party platforms. Strong automated testing practices (unit, integration, end-to-end). Ability to work independently and drive initiatives with minimal supervision. Excellent English communication skills.
