What I'm looking for

I’m looking for a frontend role where I can lead architecture decisions, build secure, accessible UX, and optimize for Core Web Vitals. I want strong cross-functional collaboration and the chance to mentor engineers while delivering production-grade fintech experiences.

I’m a Senior Frontend Developer with 6+ years of experience building scalable, high-performance web applications and Progressive Web Apps (PWAs). I own frontend systems end-to-end, from architecture and state design to production delivery, with a strong focus on accessibility and performance.

I specialize in Next.js, React, TypeScript, and modern state management (Redux Toolkit, RTK Query, TanStack Query, and Zustand). I apply Core Web Vitals optimization, code splitting, lazy loading, memoization, and Lighthouse-driven improvements to make user experiences feel fast and reliable.

In enterprise and fintech environments, I’ve delivered production-grade features and Proofs of Concept from design to production, securing client sign-off. At INFINION, I led an AI-powered banking chatbot platform and implemented secure authentication and access control using MSAL, OAuth, and RBAC.

I also lead teams and raise engineering standards—mentoring junior engineers through code reviews, pair programming, and guidance. From building reusable component libraries and internal design systems to strengthening testing with Jest, React Testing Library, and Cypress, I consistently improve quality, maintainability, and delivery outcomes.
