About me
Intro
I've spent the last 4+ years evolving from a full-stack developer into a specialist who saves enterprise React architectures from technical debt. My journey has been defined by a transition from building functional features to engineering high-scale, multi-tenant SaaS environments where performance isn't a luxury, it's a requirement.I thrive at the intersection of developer experience and system performance. Whether it's leading a legacy migration at STN or architecting platforms for 100+ enterprise clients, my goal is always to build systems that are as maintainable for teams as they are fast for users.Key Impact:Performance: Reduced production build time by 89% (4.5 min → 30 sec) by migrating Webpack to Vite.Efficiency: Cut Redux selector overhead by 85% through advanced state-management optimization.Scale: Architected multi-tenant SaaS infrastructures serving 100+ enterprise-grade clients.Core Focus:Modernizing legacy architectures (React 16 to 18/19).Scaling multi-tenant SaaS systems via Next.js and FastAPI.Performance engineering and frontend infrastructure.If your frontend is slow, messy, or dragging down your deployment cycle, I fix it. I'm currently open to discussing Senior Frontend roles or performance consulting. Let's connect.
