I architect UI systems that scale to millions
Staff Software Engineer at Meta with 11+ years of experience. I solve problems where technical complexity meets massive scale — from reducing development timelines by 96% to building systems serving 1M+ weekly users.
About Me
I solve problems where technical complexity meets massive scale. With 11+ years across Meta and VMware, my focus has evolved from building features to architecting the foundational platforms that allow entire engineering organizations to move faster and more securely.
At Meta, I operate at the intersection of performance, regulation, and developer experience. I don't just optimize apps; I build the systems that protect hundreds of millions in revenue and transform development cycles from months into days.
While I'm primarily a UI architecture specialist, I'm a full-stack engineer at heart. From setting up CICD pipelines to creating templatized code generators in GoLang, I thrive on challenges that expand my impact beyond the frontend.
UIs can make or break great applications. A great UX is the key to a successful product.
Core Impact
Velocity at Scale
Reduced development timelines from 40 weeks to 1.5 weeks with a regulation onboarding framework.
Massive Reach
Weekly advertisers supported by verification systems I architected at Meta.
Performance Architecture
Load time improvements achieved through critical path re-engineering.
Risk & Resilience
High-risk revenue secured through risk mitigation platforms I designed.
