A portfolio by Shihab Shahriar Antor
THEUNFINISHED
WORLD.
Some people see a broken system. I see somewhere to begin.
I’m Shihab Shahriar Antor. AI engineer, product builder and founder of Shahriar Labs, based in Dhaka.
An idea finds its notebook.03The strategist/
Every system has a shadow.
You can automate a decision. You still have to own it.
Routing, recovery and orchestration: tools that need explicit choices, useful limits and a way to fail well.
A plan becomes a cage.04The archivist/
Remember what matters.
A confident answer is only as good as what supports it.
Persistent memory, evaluation and a fictional forensic world. Connections need evidence, not just a beautiful graph.
Trace → inspect → reconnect.05The confrontation/
Power becomes a tool.
The best thing I can build is something you can build with.
Visual explanations, comics and programmatic films. The line that enclosed the world becomes a diagram, a comic and moving type.
A training arc never ends. ✦Control → release → creation.06The next chapter/
Other people build here.
This story gets better with someone else in it.
Product clients, startup collaborators, curious people with a difficult problem. Let’s make the next thing useful.
The page is yours.One face. Many facets.
An original fictional world inspired by the anime I love. The projects and the person behind them are real.
The opponent: a broken system.Its fragments become something useful.

The first spark. Gold rises from the ground; the stance finds its weight.

Curiosity.
Followed through.
I’m Shihab. My work crosses AI systems, product engineering and developer tools. At Shahriar Labs, I turn technical ideas into things people can use.
My BRAC University research explored astronomical imagery. These days, the questions often lead to collaboration, memory and tools for making things.
Same face.A different way to see it.
