What I'm looking for

I seek a senior engineering role in an Agile, collaborative company where I can build scalable web products, improve CI/CD and mentor engineers.

I am a full-stack developer with 8+ years building responsive, user-focused web applications using React, Angular, Node.js and modern front-end technologies. I specialize in re-architecting legacy systems into performant microservices and crafting scalable UIs for high-traffic applications.

My work includes integrating third-party APIs (Google Maps, STT/TTS, payment gateways), building ETL and data-scraping tools in TypeScript, and implementing CI/CD pipelines across AWS, GCP and Azure to ensure reliable, automated deployments. I have led migrations (AngularJS to React), created design systems with Storybook, and improved data freshness and deployment efficiency through automation.

I thrive in Agile teams, mentor junior engineers, and prioritize measurable outcomes — reduced page-load times, higher uptime, faster delivery, and improved user engagement. I seek roles where I can continue delivering robust production systems and mentor teams toward best practices.
