About me

The person behind the code

Yannis Zongo

I'm a third-year electronics and computer engineering student at INSA Rennes with a strong interest in how hardware, software, and data come together to solve real-world problems.

I've worked on projects ranging from embedded systems and signal processing to data analytics and dashboard automation. During a recent internship in Nairobi, I helped build Power BI tools to streamline financial reporting — which deepened both my technical skills and my curiosity for the intersection of tech and finance.

Outside class, I organise TEDxINSA Rennes, coordinating speakers and events that bring new ideas to campus. I enjoy working in diverse teams and building things that are technically solid and genuinely useful.

What I've built

Projects

Power BI · Python 2025

ZEP-RE Financial Dashboards

Designed and implemented automated, dynamic Power BI reports for a reinsurance company in Nairobi — replacing manual Excel workflows across several departments.

Analog · PSpice · LM358 2026

Transistor Curve Tracer

Designed a modular PCB that traces IC = f(VCE) characteristics of NPN transistors on an oscilloscope in XY mode, using a ramp amplifier, 2-bit counter, variable current source, and INA139 current measurement. Validated through PSpice simulation and lab hardware.

Signal Processing · LM358 · BC547B 2025

Ultrasonic Radar — Distance Detection

Built a full analog signal chain (amplification → precision rectification → envelope detection) to process the echo from a 40 kHz ultrasonic transducer, soldered onto a PCB and validated experimentally. Total BOM cost: ~€9.80.

VHDL · Quartus · ModelSim 2026

CPU Extension — Heron's Method Unit

Extended an existing CPU architecture in RTL by adding a Heron's-method execution unit (Pj_Unit) for iterative square root computation, a 16-bit iterative divider, and a programmable frequency divider (FDU). Synthesised and validated under Quartus Prime at 19.9 MHz.

C · SDL2 · STM32 · SQLite 2026

EII Survivor — Student Life Game

Developed a full C game simulating an exam-period platformer using SDL2, with MVC architecture, SQLite score persistence, and a custom STM32-based USB HID controller (joystick + keypad). Unit tested with CMocka, memory-checked with Valgrind.

Matlab · Simulink · STM32 2026

Automatic Control Lab — P, PI & State Feedback

Four applied control labs covering system identification (Broïda, Strejc), P/PI regulator design for thermal and flow systems, DC motor position control with tachometric feedback, and state-space pole placement — bridging Simulink simulation to real STM32 hardware.

ML · Mechanistic Interpretability · Python 2026

Why RL Forgets Less Than SFT — ICML 2026

Co-authored a paper (published at ICML 2026) introducing differential circuit vulnerability to compare how RL vs. supervised fine-tuning preserve internal attention-head circuits in LLMs. RL retained 13.5 pp more base-circuit structure at peak task performance.
