About Me
I’m on a journey to reach the highest level possible, building things that are fast, secure, and enjoyable to work with.
That mindset naturally leads me to creating tools that help developers move faster and work more efficiently — from reusable components to cleaner, more .
Curiosity drives me to explore new and understand them on a deeper level.
To me, good engineering isn’t about chasing the newest tools, but about choosing the right tools for the right problems — and understanding them deeply enough to use them with confidence.
When I’m not coding, you’ll probably find me reading , experimenting in the , or exercising.
Type-safe approach
Seamlessly bringing API types into the web environment with OpenAPI, monorepos, and automated code generation, regardless of the programming language or framework.
Performance
Optimizing build and test times by picking right tools, caching and making sure code-splitting is effective. Continuously tracking and eliminating latency and performance bottlenecks in applications.
Testing & Quality
Ensuring high code quality through unit, integration, and end-to-end testing. Catching issues early and maintaining confidence when refactoring or shipping new features.
Security
Applying modern security standards and best practices, including secure authentication flows, proper data validation, monitoring including OpenTelemetry and safe API communication.
