Operational services for fintech and gaming: KYC, fraud, support, R&D
Sofia Stars operates a distributed services organization across 11 European countries, staffed primarily at mid-level (35 of 81 tracked hires) with concentrated hiring in sales and engineering. The tech stack—Node.js, .NET, Java, Python, Kubernetes, MongoDB, MySQL, plus Onfido and LexisNexis integrations—reflects a platform-building operation rather than pure labor arbitrage. Active projects span CI/CD automation, test framework modernization, and third-party API integrations, while pain points cluster around fraud prevention, data reconciliation, and VIP customer retention—common friction points in fintech and high-stakes gaming operations.
