• • Black-Box Reverse Engineering & Replication: Complete reconstruction of a complex 3D ecosystem's architecture from a compiled binary deliverable, without any source code access or documentation — using dnSpy and AssetStudio for analysis and business logic reconstruction.

• • Ex-Nihilo Development & Cloning: Complete reimplementation of the codebase (C# / .NET) and asset structures, ensuring strict functional parity with the original system while eliminating critical bottlenecks.

• • Multiplayer Network Architecture: Design and security of session logic via Unity Relay and WebSockets — end-to-end encryption of data streams and real-time synchronization for distributed WebGL clients.

• • PDF Rendering Engine Optimization: Structural refactoring of the automated document generation pipeline — transition to isolated asynchronous pipelines, drastically reducing failure rates and latency under heavy concurrent load.

• • High Availability & Observability: Performance optimization of backend modules for an international platform — integration of automated anomaly tracing protocols and implementation of failover mechanisms.

• • Secure API Gateway (Decoupled Architecture): Development of Spring Boot microservices to securely encapsulate, transform, and distribute data from a Moodle (PHP) backend as normalized JSON endpoints.

• • Centralized Identity Management: Integration of OAuth2 SSO protocols (Google/Outlook) with automated user profile provisioning and implementation of Role-Based Access Control (RBAC).
