Memory systems and caches
I study how memory and cache design affect a computer system.
Hi, I’m Saeed.
Mohammad Saeed
Rajabi
Embedded systems engineer
and computer architecture researcher.
At Amirkabir University of Technology, I research computer architecture and memory systems. In the automotive industry, I worked on production-line testers and debuggers, supporting manufacturing and after-sales service.
ABOUT
A bit about
my work.
My work brings electronics, firmware, and software together in practical embedded systems, with a focus on automotive testing and automation.
I studied Computer Engineering at Semnan University and continued with a master’s in Computer Architecture at Amirkabir University of Technology.
In industry, I worked on testers and debuggers for automotive production lines, supporting both manufacturing and after-sales service. The systems covered test electronics and embedded firmware, operator interfaces, and collecting test results—helping teams diagnose issues and verify components such as wire harnesses, seat heaters, and switches. Alongside this work, I continue to build embedded projects and research computer architecture and memory systems.

RESEARCH
What I’m
working on.
My research is in computer architecture, memory systems, and large-scale simulation. I like to study the design, then test how it behaves in a real or simulated system.
Memory for low-power devices
My current project looks at energy-aware memory management for IoT nodes using STT‑MRAM.
HDFS, YARN, and GEM5
I have worked with HDFS on Hadoop YARN and full-system simulation in GEM5.
Energy-aware memory management for STT‑MRAM in IoT nodes
Exploring how STT‑MRAM can be managed to reduce energy use in IoT devices.
Sign-language-to-speech glove
A glove project that translates sign-language gestures into speech.
4 MB RAM design at circuit level
Designed and analyzed a 4 MB RAM circuit using HSPICE.
HDFS on Hadoop YARN and GEM5 full-system simulation
Worked with HDFS and Hadoop YARN alongside full-system simulation in GEM5.
Beyond One-Hot: CatBoost for Heating and Cooling Load Prediction
A 2025 conference paper on using CatBoost to predict heating and cooling loads.
EXPERIENCE
MOBIN SAMAN · AUTOMOTIVE
Test systems
for the factory floor.
At Mobin Saman, I developed and integrated test systems for automotive production lines, supporting factory automation and quality control. My work spanned test electronics, embedded firmware, Qt operator interfaces, and recording results in a database.

R&D Engineer, Embedded Systems
Mobin Saman Company · Tehran · 2024–2026
I worked on testers for wire harnesses, seat heaters, and switches on automotive production lines. My work covered STM32 and NXP firmware, circuit and PCB design in Altium, and Qt interfaces. Test results were sent over Wi‑Fi and stored in SQL.
I also worked with SPI, UART, I²C, CAN, and FDCAN, and built a Serial↔Ethernet converter with Flash storage.
Embedded Platforms & Infrastructure
Independent projects · 2023–present
My independent projects include MQTT-based monitoring, hardware with AVR, ARM, and ESP microcontrollers, and virtualized networks configured with Proxmox and MikroTik.

MQTT Smart Relay & Remote Control
I built an ESP32 controller that reads temperature through its ADC, monitors sensor and switch inputs, and switches relay outputs. MQTT connects the device to a self-hosted broker for remote monitoring and smart control of connected equipment.

BACHELOR’S PROJECT · AUDIO · WI-FI
Interactive Talking Cactus & Baby Monitor
For my bachelor’s project, I built my own version of the talking cactus toy. A MEMS microphone captures audio, which the ESP32 processes. Faster playback raises the pitch for a cartoon-like voice, then an amplifier drives the speaker. Wi-Fi also streams room audio to a phone, so parents can listen remotely.
