Frontend Developer building React and Next.js applications for fleet monitoring, B2B e-commerce, and real estate.

On a vehicle fleet monitoring application, I developed and maintained the client-side, migrated JavaScript to TypeScript and CRA to Vite, and optimized performance and rendering efficiency.

For a B2B e-commerce platform, I built and maintained React components and an internal UI library, integrated REST APIs, payment systems, and SAP, and helped reduce deploy time from 8–10 minutes to 2–3 minutes during a migration to TypeScript and Vite. I also developed Next.js features for a real estate application, integrating CRM, map APIs, and PDF generation.
