Fine-tuning SegFormer for land-cover segmentation
Notes on adapting a hierarchical transformer to the LoveDA benchmark — what pushed accuracy past the PSPNet and UNetFormer baselines, and what didn't work.

B.Sc. student at Chittagong University of Engineering & Technology (CUET) with hands-on experience in IC layout and semiconductor design, embedded systems, and machine learning — focused on building reliable, technology-driven solutions.
Custom and semi-custom layout in Cadence Virtuoso, physical verification (DRC, LVS), and CMOS digital logic and standard cell design.
Training and fine-tuning models — from classical ML with scikit-learn to deep learning with PyTorch, including computer vision.
Microcontroller-driven hardware — sensors, motors, and the firmware and web layers that connect them to the world.
Full front-end-to-backend builds, from UI/UX wireframes to CMS-driven sites — including an industry internship in the field.
Finishing my B.Sc. in Electronics & Telecommunication Engineering at Chittagong University of Engineering & Technology (2022–2026), with project work spanning semiconductor layout, embedded IoT systems, and applied machine learning.

Background, education, and professional experience — from IC layout to applied machine learning.
I'm a B.Sc. Engineering student with a multidisciplinary background spanning semiconductor technology, hardware development, software, and machine learning. My project work runs from custom IC layout in Cadence Virtuoso, through embedded microcontroller systems, to training and fine-tuning deep learning models — with an emphasis on system design, analytical problem-solving, and building practical, technology-driven solutions.
I'm drawn to the seam between hardware and intelligence: understanding a circuit at the transistor level, then bringing that same precision to the models and software layered on top of it.

Fine-tuned a hierarchical transformer (SegFormer, MiT-B5) for 7-class land-cover semantic segmentation on the LoveDA benchmark — 81.54% pixel accuracy and 55.31% official mIoU, outperforming PSPNet and UNetFormer baselines.

View on GitHubCustom and semi-custom IC layout, schematic capture and simulation in Spectre, and physical verification — applying CMOS digital logic and standard cell design principles. The workflow covered floorplanning, cell placement, and routing, followed by design rule checking (DRC) and layout-versus-schematic (LVS) verification to confirm the physical layout matched the intended circuit. Extracted parasitics were then used to re-simulate the design, helping validate timing and functional correctness before finalizing the layout.
View on GitHubSignal-processing work on noise reduction, implemented in MATLAB as part of the EDGE project coursework. The project involved analyzing noisy signal data, designing and applying digital filters to suppress unwanted noise components, and comparing the filtered output against the original signal to evaluate the improvement. It reinforced core concepts in time- and frequency-domain analysis, filter design, and practical signal conditioning.
