What I'm looking for

I’m looking for a frontend, fullstack, or mobile role where I can build modern, user-focused apps with React, Next.js, Node.js, and React Native or Flutter. I value collaboration, clean architecture, and creating impactful, high-performing digital products.

I am a results-oriented Fullstack Developer with 5+ years building web, mobile, and SaaS applications using React, Next.js, Node.js and TypeScript. I focus on delivering production-grade systems that drive measurable business value.

I've led teams and shipped AI-powered and data-driven platforms, including FarmSense and LinqVibe, that serve thousands of users and reduce operational friction. I prioritize performance, reliability, and clear documentation across the stack.

On the DevOps side, I improved deployment efficiency by 40% and reduced downtime to zero through Dockerized CI/CD pipelines and automation. I pair backend optimizations and caching with front-end best practices to boost adoption and speed.

I enjoy aligning engineering work with product strategy and building systems that scale — balancing hands-on development with leadership to consistently improve delivery and client satisfaction.
