What I'm looking for

I seek frontend roles building scalable React/Next.js products, with emphasis on performance, modular architecture, collaborative Agile teams, and opportunities to lead migrations and improve developer workflows.

I am a Frontend Developer with 3+ years building scalable React and Next.js applications for fintech and SaaS products, specializing in component-based architecture, SSR, and performance optimization. I deliver maintainable, ATS-friendly engineering solutions that bridge high-fidelity design and robust frontend systems in Agile environments.

I've architected modular component systems, implemented RBAC with multi-tier permissions, automated SVG-to-JSX conversion to speed UI integration, and integrated payment and KYC flows (Stripe, RevenueCat, Sumsub). I lead migrations, audits, and cross-functional projects that improve stability, performance, and developer productivity.
