What I'm looking for

I’m seeking roles where I can build scalable web and IoT systems, apply AI for automation, work in collaborative teams, and contribute to end-to-end deployments and reliability improvements.

I am a Computer Engineer with hands-on experience in full‑stack web development, IoT, automation, and machine learning, having built and deployed projects from portfolio websites to an ERP and edge IoT networks. I have worked in operations and datacenter roles, managing Linux-based infrastructure and improving uptime in high-availability environments.

I pursue applied AI and automation to solve real-world problems, designing scalable systems using Next.js, Node.js, TypeScript, Python, EdgeX Foundry, MQTT, Docker and cloud/edge tools. I combine academic study and intensive project work to deliver end-to-end solutions, from sensor integration and predictive maintenance models to responsive frontends and live deployments.
