My journey into electronics, IoT, and human-centered innovation

I started tinkering with microcontrollers to solve everyday problems—automating sensors, optimizing energy, and bringing data-driven decisions to hardware. Over time, I blended embedded programming with cloud integration, and evolved into a solution-focused professional who can both build and communicate. My aspiration is to start an electronics business focused on reliable, secure, and approachable IoT products that deliver measurable impact.

I thrive at the intersection of technical execution and interpersonal collaboration—leading demos, shaping solutions, and aligning stakeholders. Whether I’m writing firmware or crafting a value story for customers, I focus on clarity, reliability, and outcomes.
