I build AI agents, physics simulations and the occasional startup. Lately: a WhatsApp agent that keeps elderly patients on their medicine, and a black hole ray-traced from the equations up.

    6th place

    With my team I built an AI sales agent that goes from a company PDF to a booked meeting, and shows the evidence behind every lead it scores.

Selected work

Alibaba Cloud AI Hackathon · national finalist

A WhatsApp care agent that keeps elderly patients on their medication.

A caretaker adds a parent and their medicines on the website. After that the patient gets a WhatsApp message at every dose, with an Urdu voice note, and just replies. Typed or spoken, Urdu script, Roman Urdu or English: “le li” counts. If nobody answers, it nudges once and then tells the family.

The rule I cared about most: the AI never guesses about medicine. It only repeats what a caretaker has confirmed, and when two doses are pending and the reply is unclear, it asks which one.

Black Hole

A Schwarzschild black hole, ray-traced from the geodesic equations up.

I watched Kavan's video on simulating a black hole in C++ and wanted to actually understand it, so I rebuilt it in SFML one small program at a time. Straight rays first, then an event horizon, bending light, RK4, and finally a GPU ray tracer with a Doppler-shifted accretion disk.

When I checked the original shader against the textbook formula, its shadow came out about 40% too small. One term used r where it needed r − rₛ, and the photon sphere vanished. Mine gets the size right, and it's the one running at the top of this page.

AgentHack by AI Season · 6th of 40

An AI sales agent that turns a company PDF into booked meetings.

You give it a company document and a description of the customer you want. It finds prospects, drops the bad ones cheaply, researches the promising ones, scores them, writes the email, reads the reply, books the meeting and pings you on WhatsApp.

The language model never touches the numbers. Every score is plain code with a source URL behind each point, so the same evidence always gives the same result.

About
Abdul Zakir with a microphone, asking a question from the audience

fig. 2 me, mid-question

I'm Zakir. I grew up in Hyderabad, Sindh, and moved to Islamabad for computer science at FAST NUCES, where I'm in my second year.

Most of what I build starts with wanting to understand something. The black hole began as a video I couldn't stop thinking about. MedNuskha began with a simpler question: would an elderly parent ever learn a new app? They wouldn't, so it lives in WhatsApp.

I like problems where being slightly wrong matters, so I test things, measure them and write down what I find.
