AppGreat operates a full-stack outsourcing shop — software development, DevOps, NOC/SOC, and technical support — anchored in a polyglot cloud stack (Azure, AWS, GCP, Kubernetes, ArgoCD). The project mix reveals a sharp tilt toward operational resilience: crash-dump analysis, anomaly detection for live gaming, real-time event pipelines, and identity/biometric systems. Hiring skews heavily senior (8 of 14 roles), concentrated in engineering with emerging depth in security and product, suggesting maturation into higher-complexity delivery and internal tooling.
