About

Engineering with purpose

I'm a third-year Electrical Engineering student at the Higher Colleges of Technology in Sharjah, UAE, maintaining a perfect 4.00 GPA while pursuing research and engineering projects that directly address real-world sustainability challenges.

My work spans the full stack of engineering — from designing PCB circuits in EasyEDA to training machine learning classifiers in Python. I've presented research at GITEX Global and Abu Dhabi Sustainability Week, and my solar tracker project was recognised with an IEEE Honourable Mention.

Currently investigating grey water recycling systems for UAE residential buildings, targeting publication at the ASCET Conference 2026. I'm passionate about applying engineering to sustainability — the challenge that defines our generation.

Representation-Aware Denoising for
Noise-Robust Environmental Sound Classification

A systematic study of classical and learned enhancement methods for environmental sound classification (ESC) under real-world noise. Evaluates three architecturally distinct pipelines — a 1D CNN on raw waveforms, an MFCC-based Subspace Discriminant Ensemble, and an Audio Set-pretrained CNN14 — against additive white Gaussian noise and real-world traffic noise across SNR levels from −10 to +20 dB. Investigates adaptive Wiener filtering, MMSE-LSA, and U-Net denoising, demonstrating that enhancement effectiveness depends critically on the interaction between the denoising method and the downstream audio representation. The strongest pipeline, CNN14, achieves 87.5% clean accuracy and recovers up to 24.30 percentage points at −5 dB SNR using U-Net enhancement.
