The tech stack reflects a hybrid engineering org: React/Vue frontend work paired with Python backends (FastAPI, Flask, Django), Java services, and enterprise infrastructure (Oracle, SQL Server, PostgreSQL, VMware). Active hiring is heavily weighted toward senior engineering roles, concentrated in Turkey, with concurrent focus on CI/CD process design and APQP/PPAP automotive compliance workflows—signaling production-system modernization across both legacy telecom and growth-stage automotive divisions.
