EMG-Driven Game Prototype (Senior Design)

Embedded + Signal

sEMG-driven interactive game: sensor acquisition, real-time envelope processing, on-device UI.

Stack: C, MCU firmware, SPI/I2C peripherals, real-time signal processing, OLED UI

Proof: Working firmware + game loop in repo; designed under memory/timing constraints

Robotics 2D Perception + Control Loop Demo

Robotics + CV

2D differential-drive sim with synthetic camera frames; perception via segmentation; closed-loop heading control.

Stack: Python, simulation, segmentation, control loop

Proof: End-to-end pipeline runnable from repo; outputs deterministic artifacts (logs/plots/GIF)

RAG-Lite Retrieval + Evaluation (TF-IDF)

AI SWE + Eval

TF-IDF indexing + cosine similarity retrieval, with an offline Recall@K evaluation harness.

Stack: Python, TF-IDF, cosine similarity, evaluation harness, CLI

Proof: Reproducible baseline retrieval + metrics; clean path to add embeddings/reranking later

About

I build practical systems where correctness, repeatability, and debugging discipline matter. I prefer concrete demos and measurable results over broad claims.

Core: C/C++, Python, Linux, Git
Systems: embedded firmware, real-time loops, instrumentation
Robotics/AI: perception pipelines, control loops, retrieval + evaluation
