What I'm looking for

I’m looking for a role where I can modernize front ends with TypeScript, ship reliable serverless back-ends, and run analytics/A-B testing safely—while mentoring teams with strong CI/CD and observability.

I’m a Full Stack Engineer focused on modernizing products and enabling data-driven decision making. At my current role, I led front-end modernization by migrating from JavaScript to TypeScript, improving scalability and maintainability. I also implemented analytics, A/B testing, and cookie compliance integrations to strengthen experimentation and policy alignment.

On the back-end, I build and optimize APIs using Node.js and Azure Functions, adding robust validation and encryption. I’ve also delivered feature flags, automated testing, and CI/CD pipelines to increase release confidence and reduce manual QA effort. I enjoy mentoring teammates and raising code quality standards.

My tooling spans React, Redux, Material UI, and Storybook on the front end, plus Jest, React Testing Library, and CodeceptJS for testing. In DevOps, I’ve worked with Azure pipelines, YAML migrations, SonarQube, WhiteSource Bolt, ARM templates, and Application Insights for monitoring.
