I'm genuinely curious about how robots think, how a PCB comes to life, and how attackers break into everything from IoT devices to industrial systems. I like automating boring stuff with scripts, learning new things, starting new projects and occasionally banging my head against the wall when things don't work. Currently studying Electronic Engineering at HSHL and actively looking for my next challenge

About

Hi, I'm Sadim.

I'm an Electronic Engineering student at Hochschule Hamm-Lippstadt, currently in my 6th semester. I started programming in 10th grade, got curious about PCB design and security early on though it took time before things really clicked. Studying Computer Science in Bangladesh introduced me to web technologies, DevOps, and machine learning and landed me my first freelance client. Then I moved to Germany and went all-in on embedded systems the place where hardware meets code meets real-world machines.

Right now my time goes into embedded systems and ML coursework learning C++ for embedded systems, working through FPGA logic in VHDL, and tinkering with ML models through hands-on projects. Still early in the journey, but I learn by doing real things rather than just reading about them.

Outside of engineering, I actively explore cybersecurity working through TryHackMe and HackTheBox challenges, reverse engineering binaries with Ghidra and pwndbg, and building toward my PNPT certification from scratch.

I'm currently looking for a Werkstudent or Praktikum position in embedded systems, robotics, or autonomous driving somewhere I can bring real engineering value and keep growing fast.

🏆 2nd PlaceGrade 1.0Team Project

Autonomous Driving System

I contributed to a team-built autonomous robot using Arduino Uno, implementing line following and obstacle detection with IR and ultrasonic sensors. I did the mechanical design in SolidWorks, 3D printed custom ultrasonic sensor mount, wrote the foundational C++ template, produced SysML documentation, and assembled the visual Git repository document. The team placed 2nd out of all competing teams project graded 1.0.

Uni Project

Traffic Light Control System

I built a T-junction traffic light controller using two Arduino Uno boards talking to each other over UART. I implemented the full finite state machine in Embedded C++ to handle traffic phase sequencing and timing across both boards, then documented the system architecture with UML Class and State Diagrams.

Personal Project

Alzheimer's Disease Detection API

I built an end-to-end ML pipeline to classify Alzheimer's indicators from tabular clinical data. I ran EDA with pandas and NumPy, trained an ANN using TensorFlow/Keras for binary classification, then deployed the model as a REST API with FastAPI and validated all endpoints with Postman.

Lab Showcase

Kry0Steg

I built a native desktop cryptographic steganography tool in C++ using GTKMM for the GUI. I implemented Caesar cipher, ROT13, and null cipher steganographic encoding, then presented the project at the end-of-semester lab project showcase.

Freelance · UpworkClient Delivered

AutoSeekOut, Web Scraping Automation Tool

I engineered a Python/Selenium automation tool for a US-based client via Moonhub on Upwork, replacing a slow manual data-entry pipeline entirely. I extracted, cleaned, and structured web data into validated CSV deliverables — significantly cutting processing time — and delivered everything on time under a real client contract.
