We work as an AI-native product design and development partner, the kind you bring on when you want to build something real from the ground up. I’m Ishaan, co-founder of TechBrig, and I personally lead every engagement. I also operate as a fractional product designer on many of our projects, working directly on UX, flows, and product decisions alongside building out the underlying systems. When you work with us, you’re not handing things off to a faceless agency, you’re getting a hands-on partner who thinks and operates like an in-house teammate, fully invested in the outcome. We bring together product design, engineering, and AI automation expertise to help teams go from 0 to 1. That means shaping the product vision, designing intuitive experiences, and building production-ready software, whether you’re launching something new or layering AI into an existing system. We’ve helped startups design and ship full-scale products, from early MVPs to complex internal and enterprise tools. In parallel, we work closely with traditional businesses to implement AI and automation into real workflows, from recruiting and legal to accounting and operations, helping teams scale without adding unnecessary complexity. Our philosophy is simple. This isn’t just about clean code or the right stack. It’s about building systems that actually work in the real world, with someone who takes ownership, moves fast, and understands both product and execution. If you’re looking for a partner who’s deeply involved, product-minded, and able to bridge design, engineering, and AI, I’d love to talk.

I'm Abdullah — AI Engineer, published AI researcher, Kaggle Expert, and Roboflow Expert from Pakistan. I have a peer-reviewed research paper published in Sensors (MDPI, SCI Q2) on a custom lightweight AI model I designed from scratch for real-time disease detection in medical images. Two more research papers are currently under review in Nature Communications Medicine and Computer Methods and Programs in Biomedicine — some of the most competitive journals in AI and medical research. I don't just use AI tools. I build, train, and publish them . Computer Vision and Object Detection I build custom object detection, image segmentation, and real-time tracking systems using YOLO, ResNet, EfficientDet, and Vision Transformers. I have delivered 100K+ annotated and trained images across medical imaging, agriculture, surveillance, and industrial automation. My models run on both cloud servers and small edge devices like NVIDIA Jetson Nano and Raspberry Pi. Deep Learning I design and train neural network architectures including CNN, LSTM, Transformer, and GAN for image classification, medical diagnosis, text processing, time-series prediction, and generative AI applications. Frameworks: PyTorch, TensorFlow, Keras. Machine Learning I build complete ML pipelines for classification, regression, forecasting, clustering, and anomaly detection — from raw data to deployed API. Every model includes performance reports, SHAP explainability, and FastAPI or Flask deployment. Frameworks: Scikit-learn, XGBoost, LightGBM, CatBoost. Reinforcement Learning I build and train RL agents for robotics, game AI, simulation, and automation using PPO, DQN, SAC, and TD3 via Stable Baselines3 and RLlib. Simulation environments: PyBullet, MuJoCo, Gazebo, Isaac Gym. Image Annotation and Dataset Preparation I provide professional data labeling — bounding boxes, polygons, segmentation masks, keypoints, and video annotation — in YOLO, COCO JSON, Pascal VOC, and custom formats. I use Roboflow, CVAT, LabelStudio, and SuperAnnotate with strict quality control throughout. Every delivery includes clean documented code, full performance benchmarks, and production-ready output. Message me with your project details before ordering. I personally review every brief before accepting.
