Standing desk and systems illustration

Hi, I'm Hamidul - I help businesses ship systems that grow.

I turn conversion leaks, expensive media, and brittle integrations into product systems customers feel and P&Ls notice.

How I got here.

Product systems at the desk

I've been obsessed with understanding how things actually work - not just that code prints a number, but how the CPU, memory, and binary execution produce that result. That curiosity drives how I build product systems today.

As a performance and infrastructure-minded product engineer, I care about queries, caches, Core Web Vitals, and shipping ownership with a team - so products stay fast when the business starts to grow.

How I help businesses

  • Find the revenue leak or cost spike
  • Design the system that removes it
  • Ship something the team can own
  • Keep it fast when traffic gets real

Hardware interest - sensor to software to actuator

Away from the browser, I dig into embedded and low-level work: soldering boards, wiring robots, flashing ESP32s, and writing the C/C++ that talks to real hardware.

Camera, radar, microphone, sensors, ADC, MCU, GPIO, PWM, SPI, I²C, UART, CAN - the full path from physical signal to software decision to actuator. That same systems thinking shows up in the product platforms I ship for businesses.

What I'm exploring

  • ESP32 / MCU firmware
  • Sensors, ADC, and signal paths
  • Robotics and actuators
  • Bare-metal and RTOS habits

Here are some of the values I live by.

How I show up on a team.

Depth

I dig until I understand the mechanism - then I can optimize and teach it.

Collaboration

Great systems are built with people. I communicate early, review carefully, and leave codebases kinder.

Shipping

Ideas without delivery don't count. I take problems from ambiguity to production.
