What I'm looking for

I seek a role that fosters innovation, collaboration, and growth opportunities.

I'm a polyglot programmer with a decade of experience in building scalable applications across various domains, including cybersecurity, fintech, and data engineering. My focus is on delivering high-quality, maintainable code in fast-paced environments, ensuring that both good and perfect solutions coexist harmoniously.

Throughout my career, I've held senior engineering roles at notable organizations such as FOSSA and ActBlue, where I optimized application performance and led the development of critical features. My technical expertise spans multiple languages and frameworks, including Rust, TypeScript, and Ruby on Rails, allowing me to tackle complex challenges and drive impactful results.

In addition to my technical skills, I am passionate about fostering a collaborative team culture, as demonstrated by my efforts in establishing blameless retrospectives and RFC-based planning. I believe in the power of teamwork and communication to achieve our goals and create innovative solutions.
