About Me

Passionate about creating meaningful digital experiences through clean code and innovative solutions

My Journey

I'm a software engineer with over 4 years of experience building scalable web applications, working on fast growing startups, and established tech companies. My passion lies in creating elegant solutions to complex problems while maintaining a focus on user experience and code quality.

When I'm not coding, you'll find me cycling around NYC, exploring new coffee shops, or reading a good sci-fi (Dune is my favorite). I believe in the power of technology to make a positive impact and excited to work on projects that matter.

Currently, I'm focused on low-level Rust development for the Amazon Prime Video app. My background previously focused on cloud architecture working inside AWS's Managed Services organization.
