About Me

I am a software developer with professional experience since 2012, specializing in Android mobile application development.

My main professional focus is building reliable, maintainable, and user-oriented mobile applications. Alongside my mobile background, I also work heavily on a large-scale personal engineering project that covers cross-platform client development, Rust backend services, multiplayer infrastructure, Kubernetes-based deployment, CI/CD automation, and system-level anti-cheat research.

This project started as a hobby, but it has grown into a serious long-term engineering effort and now takes a significant part of my development time.

I enjoy working across different layers of software, from mobile applications and client-side systems to backend services, infrastructure, automation, and low-level security concepts.


Current Focus

My core professional background is Android and mobile application development. In addition to that, I am currently spending significant time on a large-scale, cross-platform software ecosystem.

This work includes both client-side and server-side development:

  • Cross-platform game/client development
  • Rust-based backend and game-server development
  • Multiplayer server architecture and real-time session management
  • Server-authoritative gameplay validation
  • Event-driven and service-oriented architecture
  • gRPC-based synchronous service communication
  • NATS JetStream-based asynchronous event streaming
  • PostgreSQL-backed domain data ownership
  • Kubernetes-native deployment and runtime operations
  • GitOps workflows with ArgoCD, Helm, and Kustomize
  • CI/CD automation, contract validation, and quality gates
  • Container image build, registry, and deployment pipelines
  • Vault-backed secret management with External Secrets
  • Cloudflare Tunnel-based secure service exposure
  • Observability, monitoring, runtime health checks, and operational reliability
  • AI-assisted CI failure diagnosis and automated remediation workflows
  • Cross-platform anti-cheat research and development
  • Kernel-level security concepts for Windows, Linux, and macOS
  • Runtime integrity, process monitoring, endpoint posture, and telemetry-driven protection
