What I'm looking for

I’m looking for a role where I can own production-critical work end-to-end—building maintainable backend services, stabilizing complex systems, and collaborating closely with stakeholders to deliver reliable, security-aware outcomes.

I’m a software engineer and game developer who takes ownership of production components in a custom game engine. I work directly with stakeholders to clarify requirements and constraints, and I investigate and stabilize complex engine behavior with solutions aligned to business and regulatory needs.

On the backend, I plan and build service-oriented, maintainable production systems for greenfield applications and long-lived codebases. I’ve delivered enterprise backend work across data storage, security, network communication, authentication integration, and CI/CD/production deployments, combining strong architecture with reliable cloud tooling and pragmatic collaboration.
