Message

At Railsware Products Studio LLC, I designed and implemented email campaigns and contact management for the mailtrap.io email marketing platform. Within the first three months, it onboarded 60+ customers with 1.6M+ contacts.

I also architected and implemented a CMS-powered family of web portals for amazingdiscoveries.org, and created an automated video upload, encoding, and publishing pipeline for adtv.watch that reduced publishing time from hours to minutes. For coupler.io, I designed and implemented Stripe billing functionality that enabled the product to start generating revenue.

At GitLab Inc., I integrated security scanning tools into the static application security testing pipeline. I’ve also been building Rust projects, including a Zed settings sync extension and an interpreter for the Lox programming language.
