Rahimi Rusyuddin.

Software Engineer/Full-stack Developer

I build security and data systems, and I publish research on the models behind them. At U Mobile I designed CYFER ONE, an internal platform that discovers servers across the network, consolidates them into a single asset view, and drives segmentation decisions. Alongside that I am first author on deep-learning and NLP work in IEEE Access and IJ-AI. The two halves feed each other: research keeps the engineering honest about what actually works, and shipping keeps the research honest about what actually runs.

Systems that run in production

Security and full-stack engineering: platforms that had to work against real infrastructure, on a deadline, and survive being handed to someone else.

02 · Research

Models, datasets, and papers

First-author work in computer vision and NLP, published across IEEE Access, IJ-AI and conference venues. Lightweight architectures, low-resource languages, and the datasets they needed.

Publication record

A comparative study of lightweight CNN architectures for recognising 11 classes of East Coast Malaysian kuih, settling on a MobileNetV2 backbone that holds 98.17% accuracy at 58 ms inference. The classifier is paired with a dual-reading interface: a KKM nutritional lookup for verified calorie data, and Gemini 2.5 Flash for cultural context the lookup table cannot carry.

A lightweight CNN prototype reaching 98.17% accuracy across 11 East Coast Malaysian kuih classes, integrated with Google Gemini 2.5 Flash for calorie estimation and cultural knowledge generation.

Thematic classification of Malay pantun. A regex-based preprocessing pipeline segments pembayang from maksud before case folding, tokenisation and Porter stemming; an SVM baseline on TF-IDF features is then benchmarked against a custom PyTorch TextCNN. The winning model ships behind a Flask API that lazy-loads weights to keep inference under one second.

A ResNet50 framework covering 11 varieties of East Coast kuih at 95.41% accuracy, trained on a purpose-built hybrid dataset of 1,227 images and paired with a KKM-based calorie lookup.
