ABOUT ME
Software engineer with 15+ years of experience bridging product, business, and engineering leadership
Software engineer with 15+ years of experience bridging product, business, and engineering leadership

Software engineer with 15+ years of experience bridging product, business, and engineering leadership; trained in economics and statistics, with extensive self-directed study of human psychology, and a strong focus on user experience.

Over the past decade, I’ve led cross-functional teams, aligned stakeholders across departments, and overseen multiple products in parallel from concept to market, ensuring delivery creates measurable business value, while keeping user experience at the core.

My skills include Swift, SwiftUI, Node.js, Express.js, remix.run, React.js, TypeScript, React Native, Postgres, SQL, HTML, CSS, REST, unit / integration / e2e testing, CI/CD. One of my biggest desires is and has always been to create or be part of a team that creates a great product.

I was proactively involved in business, product and architectural decisions and I drove the brainstorming and implementation of complex features, aligning stakeholders and syncing multiple teams and leads to find the best solutions. Among others, I reduced app bandwidth usage related to images by 40%+, and reduced bugs and failures related to cross-project and cross-team collaboration by 90%+.

Along with 3 friends, we set out to create a tool that will automatically find, generate and run all the tests required for a product. During this time, I built multiple microservices/micro-web-apps, most of which communicate with each other, some with large amounts of data and sensitive information which had to be secured or obfuscated.

The main goal of the app is for users to save their fidelity cards digitally (or request new ones), combined with the conveniences of displaying merchants & their offers, and having a shopping list at hand. There's also a friends feature, with which users can share their shopping lists — shopping together, faster and smarter has never been easier!
