MUHAMMAD ABU SAYEED / SELECTED WORKENGINEERING WITH PERSPECTIVE

Complexity in.
Clarity out.

A CLOSER LOOK AT WHAT I BUILD

Intelligence in the interface.
Intention in the architecture.

Retrieval supplies relevant context to the language model. Prompt design connects the question to the evidence.

AI/ML01 / 06

From documents.To understanding.

Turning unstructured information into structured reports with language models and retrieval.

WHAT IT MAKES POSSIBLE

Structured information and reports for document analysis and compliance review.

IN FOCUS / BIOMEDAIHEALTHCARE × HUMAN-CENTRED SOFTWARE
A PERSONAL EXPLORATION IN HEALTH TECHNOLOGY

Complex science.
Human understanding.

I’m building BioMedAI around a simple ambition: make complex medical information easier to explore, understand, and work with. From the details of a patient encounter to the extraordinary architecture of the human body, this is where my curiosity about medicine meets my love of building software.

01 / THE PLATFORMBioMedAI
℞PRESCRIBA
THE ENCOUNTER, CONNECTED.
Encounter→Prescription→Patient story

More context.
Less friction.

Prescriba brings prescription drafting, patient visits, and trends into one connected prototype. Designed around the workflows of Bangladeshi doctors, it explores how AI assistance, explicit checking rules, and thoughtful interfaces can fit together.

02 / THE HUMAN ATLASExplore in 3D
Watch the anatomy video

A body of knowledge.
A world to explore.

The Human Atlas turns anatomy into an interactive landscape. Explore the body in 3D, search for structures, isolate a part, and look through layers to discover how its systems fit together. Built on the open Z-Anatomy project.

“The most interesting part is turning complexity into something someone can actually use.”

ON METHOD

Good systems begin
with better questions.

01

Understand

Start with the person and the problem. Find the constraints before choosing the technology.

02

Make it clear

Design the smallest useful system. Keep its boundaries explicit and its decisions easy to follow.

03

Make it dependable

Validate inputs, account for failure, and document the decisions that the next engineer will need.
