What I'm looking for

I’m looking to own end-to-end product features and architect scalable, AI-driven systems. I want a team that values clean architecture, measurable performance improvements, strong CI/CD, and thoughtful code reviews with room to mentor.

I’m a Senior Full Stack Developer with 8+ years of experience architecting and deploying scalable, AI-driven platforms. I’ve owned features end-to-end—from ideation to production—delivering high-impact solutions at Meta, McKinsey & Company, and Home Depot.

At McKinsey & Company, I led the “AI Insights” platform, integrating caching and optimizing backend performance, while collaborating with data scientists to deploy AI models as microservices. My approach emphasizes clean system architecture, performance optimization, CI/CD automation, and mentoring—raising test coverage from 60% to 90% and improving responsiveness through real-time UI and monitoring.
