This is Dr. Khan, a versatile freelance working as a professional researcher, trainer, IT specialist and teacher from the last 15 years in different sectors of Pakistan, Afghanistan and UAE. Having a great experience in the research, I decided to provide my services here on Upwork to help the companies and the individuals to be successful in the industry. My work has been published in well reputed international academic journals and conferences and also served as an editor and reviewer for 30+ reputed journals in various fields of engineering and computer science. I pride myself in providing quality work – no matter the job – to all my clients. My background as an associate professor at the university level has given me a unique perspective to examine academic writing, which will be beneficial to you as a client. I earned a PhD in Electronic Engineering from International Islamic University, writing my dissertation on Denoising and Segmentation of Blood Vessels in Retina Images using Statistical Techniques. I also have a MS Electronic Engineering(Communication and Signal Processing) from the same university with my dissertation on Initial Design and Development of Indigenous Synthetic Aperture Radar (SAR) Demonstrator, As a scientific expert, I will provide you with key insight and research into whatever topic assigned, accessing a variety of source materials to complete the project. My experience in academia, and now on this platform, has allowed me the chance to edit and proof-read hundreds of term papers, thesis, dissertations, book chapters, and journal articles. As a former student, I know how important it is to produce a well-written paper to not only get a good grade in your class, but also to use that paper as a springboard to further your academic career. Since I am currently a writer and researcher, I also know how important it is to keep your name in the field by producing work that is publishable in peer reviewed publications. I have been through the process and know what those publications expect from their writers. Although my background is in engineering, I have helped edit and proof-read papers from scores of different backgrounds – from computer science to biology, from economics to anthropology and from social science to management sciences as well. Over the course of teaching for 10+ years at the university level, I acquired experience in a number of areas that you can utilize. I have extensive experience grading papers and using rubrics, writing course material, and creating my own lectures using Microsoft PowerPoint. I have also studied various pedagogical theories and practices. As a Turnitin and Grammarly Premium account holder, I can ensure that all of my work is 100% unique content, so you do not need to worry about copy & paste jobs. I also pass my work through premium Grammarly to ensure that it is free from grammatical errors. Here are my expertise but not limited to, ★ Editing and proofreading academic texts (e.g. doctoral theses, research papers, funding proposals, research reports, etc.) ★ Citation/formatting styles (APA, Chicago, IEEE, MLA, Harvard, etc.) ★ Plagiarism-free work ★ Literature Review ★ Research Papers & Proposals ★ Research Article ★ BS/MS/PhD Thesis/Dissertation ★ Statement of Purpose ★ Webpages & resumes etc. If you are looking for any help related to my skills, you can contact me and we can discuss the project. Looking forward to working with you. Best, Dr. Khan!

I build deep learning systems that work under real-world constraints, not demos. Ph.D. in Machine Learning, 10+ years across ML, computer vision, and applied AI, with Q1 publications and reviewer roles at A*/A AI venues. I take on the problems where the obvious approach fails: long-tail semantic segmentation, weak/pseudo-label pipelines, frozen-backbone (DINO/ViT) + DPT architectures, and training under hard VRAM/RAM limits. R&D Engineering - End-to-end CV pipelines: semantic/instance segmentation, detection, classification (PyTorch, OpenCV) - Foundation-model adaptation: DINO/ViT backbones, SAM/SAM3 prompting, LoRA, DPT heads - Weakly-supervised & pseudo-label systems: CAM seeding, confidence-gated verification, ignore-index/ternary labels, self-training - Training engineering: loss design (Focal-Tversky, weighted CE), class-imbalance handling, multi-GPU pipelines, checkpoint/resume/early-stopping, OOM-safe execution - Diagnosis-first debugging: root-cause isolation before patching, one-variable-per-run experimental discipline Applied ML - Model design, training, optimization, and evaluation on messy real-world data - Reproducible experiments, versioned caches, documented and auditable code - Domain-specific systems (industrial inspection, standards-driven labeling) Research Delivery (on request) - Publication-ready manuscripts, methodology design, and result interpretation - Systematic literature reviews restricted to top venues (CVPR/ICML/NeurIPS-tier) - Figures, tables, and quantitative visual analytics Stack: Python, PyTorch, OpenCV, DINO/ViT, SAM/SAM3, DPT, Hugging Face, conda, Linux, multi-GPU CUDA. I deliver working systems with clean, documented code and hold strict timelines. If you have a hard CV/ML problem, especially one where off-the-shelf models underperform on your data, send the details, and I'll respond with a concrete technical approach.
