About

Between physics, engineering, and measurement

I sit where the hardware ends and the data begins — and I like problems that need both halves to be right.

I hold an MSc in Astrophysics with Advanced Research from the University of Hertfordshire and a BTech in Electronics and Communication Engineering. The electronics background gives me practical grounding in hardware, sensors, embedded systems, signal handling, and experimental setups; the astrophysics background gives me training in measurement problems, data analysis, physical interpretation, and astronomical systems.

My interest is in building bridges between instruments, data acquisition, control systems, and scientific interpretation. Alongside research, I develop unified astronomical dashboards and interactive open-science tools to make scientific workflows more visual and inspectable.
