I've built and delivered production web and mobile applications across React, Next.js, Node.js, and React Native.

At Sparktech Agency - BDCallingIT, I expanded from frontend to full-stack development within three months and into React Native within seven, delivering two ecommerce mobile applications end to end.

I migrated client integrations from REST to GraphQL, built real-time chat and notification systems with Socket.IO, and supported live synchronization across concurrent users.

At ZenDevz, I built and deployed the agency portfolio with Next.js, Prisma, and PostgreSQL, led international client projects from requirements through deployment, and completed 35+ code reviews as a technical lead.
