M Hamid Jamil. From the screen to the circuit. Software, mobile and connected hardware.

I build the whole journey.

I'm Hamid, a software engineer in Lahore, Pakistan. My work connects web platforms, mobile applications and physical devices: from a restaurant's kitchen board to an institute's fee desk, from a home-visit booking to an arrival alert delivered through an ESP32.

I enjoy taking a practical problem through interface design, backend engineering, deployment and day-to-day operation.

Selected work

Every project below has a case study covering why it exists, what I built and how it fits together.
