THE WORK OF OBAIDULLAH
Curious by nature.
An engineer by craft.
I’m Obaidullah, co-founder of Klassifiers, CTO at Contecify, and a machine learning engineer.
I build tools that make AI useful and share what I learn along the way.
AI, software & experimentsFrom ideas to working software
01 / THE PORTFOLIO
Selected work.
A few things I’ve built,
from useful tools to research explorations.
From events to insights
A healthcare data pipeline that carries synthetic patient events through validation, storage, and into an interactive dashboard.
Kafka / FastAPI / Prefect
Making sense of MRI
Exploring multi-region brain tumor segmentation with multimodal MRI and an attention-based U-Net.
PyTorch / U-Net / Medical imaging
A closer look at crop health
Leaf detection, disease classification, and a robot to collect images in the field. My award-winning final year project.
YOLOv5 / CNN / Robotics
Always making room for the next idea.More on GitHub
02 / RESEARCH
AI with clinical context.
Exploring how language models can support
evidence-based cancer care.
HEALTHCARE AI · RETRIEVAL-AUGMENTED GENERATION
An AI Clinical Governance Assistant
Our research explores how an AI assistant can assess cancer treatment plans against NCCN guidelines, combining hybrid retrieval with an open-source language model and evaluation by oncologists.

03 / THE PERSON BEHIND THE WORK
A bit about me.
I like getting things out of notebooks and into people’s hands.
My work spans language models, computer vision, and the software that brings them together. I’ve built healthcare AI systems at CureMD and Persivia, and now work on computer vision at Ebryx.
Alongside co-founding Klassifiers and serving as CTO at Contecify, I’m pursuing a master’s in AI at LUMS. This is where I collect my own tools, experiments, and projects as they take shape.
When I’m not building, I’m probably watching cricket, playing it, or talking about it.
