Full Stack Developer at SmartBear who built a test-data lookup endpoint used by customer support.

At SmartBear, I independently designed and built an end-to-end endpoint that returns test data by test ID, becoming the primary lookup tool used by customer support. I also added CSV uploads for batch test execution and implemented Amplitude analytics tracking.

On SmartBear's Visual Test, I reduced security vulnerabilities by 40% through dependency audits and upgrades, and reduced technical debt by 35% by adding unit tests across roughly 70% of the codebase. I also contributed to integrating the product's image-comparison functionality into a sibling internal product.

At Ampcasd, I led four developers building a custom CMS and web platform for a cultural center client in Germany, from discovery through production launch. The platform supported registrations, subscriptions, bookings, and ticket sales, and grew to 1,600+ registered users and 1,800+ subscriptions sold. I’m also building a personal home construction budget application with Next.js, NestJS, Redis, and Stripe.
