Background

I'm a multi-platform specialist with deep experience in web (React + TypeScript), iOS (Swift), and Android (Kotlin). I leverage my unique artistic background with solid engineering practices and empathetic leadership to craft amazing consumer and enterprise experiences. My passion lies at the intersection of elegant code, beautiful design, and products that genuinely improve people's lives.

Currently, I serve as Technical Lead at Future, where I joined pre-product launch and helped scale the company to multi-million dollar ARR by building and leading projects across web, iOS/macOS, and Android. I've recruited and mentored teams from scratch, architected novel systems to ingest and visualize biometrics data from Apple Watch, and built tools that helped scale our coaching operations 6x while maintaining an 80-90+ NPS. I'm also the founder of Dreamplate, a platform empowering SMBs to deliver incredible mobile experiences with bespoke apps, websites, and AI-driven tools.

Throughout my career, I've been fortunate to work with exceptional teams at companies like Keelo (featured by Apple and Google Play), Realstax (backed by Stanford and leading tech investors), and Bitcasa (founding team member, raised $20M). Whether leading technical initiatives, building products from zero to one, or mentoring engineers, I focus on creating bonds with teammates, leading by example, and fostering productive environments where great work happens naturally.
