What I'm looking for

I'm looking to lead and build scalable web and mobile products, especially in real-time systems, IoT, logistics, or operational software, while mentoring engineers and owning delivery from architecture through production.

I'm leading product development at UptimeLinked (Hungrybulb Technologies), building six Industrial IoT platforms that turn real-time machine-sensor data into manufacturing insights.

Previously at Pantheon Digital, I led the development of LoadingWalla, Zfour HRMS, and the company website, progressing to project lead within my first year. I shipped logistics and HR products across web, Android, and iOS, including systems used by more than 2,000 users.

I build with React Native, React, Next.js, Node.js, TypeScript, and scalable backend architecture. My work includes Redis Streams geolocation ingestion, real-time socket features, secure APIs, CI/CD pipelines, and performance improvements of up to 40%.

I enjoy taking products from architecture to delivery, mentoring engineers, and turning operational challenges into reliable web and mobile experiences.
