What I'm looking for

I seek a role where I can lead engineering teams, build scalable frontend/mobile products, mentor engineers, and drive impact in an Agile, product-focused startup environment.

I am an engineering manager and frontend developer with 4+ years building high-performance web and mobile applications using Angular, Ionic, TypeScript, Flutter and related technologies. I drive measurable product outcomes by improving UI/UX, optimizing performance, and implementing reusable component systems that accelerate delivery.

As a CTO, I led a 5-person engineering team to launch an MVP in under six months, architected systems targeting 99.9% uptime and supported growth to 1,000+ users. I have repeatedly reduced load times, cut integration errors, and improved user engagement through pragmatic engineering and close collaboration with product and design.

I prioritize mentoring and Agile practices to increase team velocity and cross-functional capability, and I am currently advancing my technical leadership through a Master’s in Information Technology.
