Senior Product Designer for complex B2B SaaS, healthtech, and enterprise platforms

8+ years designing multi-role platforms, data-dense dashboards, and mobile products that ship and hold up in production.
I embed with product teams, think in systems, and push back when the brief is wrong.

Why work with me

I think like a product person and design like a senior IC.

Eight years designing complex B2B products teaches you that pretty screens are not the deliverable. The deliverable is a product that works in production, holds up under edge cases, and does not generate support tickets. That is what I optimise for.

I do not wait to be handed a brief. I ask why the brief exists, whether the problem is framed correctly, and what the second-order effects of the proposed solution are. PMs bring me into roadmap conversations and feature trade-off discussions because design decisions and product decisions are the same decision.

I work fully remote, async-first, and across time zones. My current role at Karaz Platform is remote from Dhaka. I am used to daily standups on Slack, async design reviews in Figma, and keeping engineering unblocked without being in the same room.

Kind Words

From the people I've worked with.

In my 20 year software career, Shahriar is one of the best designers I've had the pleasure of working with.
Michele B · Founder & CEO · IdeaClouds
Shahriar redesigned our reporting product after two prior attempts with other designers stalled. He didn't need the data complexity explained twice — he asked sharper questions than we did, shipped Figma our engineers could actually build from, and pushed back when we were about to make a bad call on the IA.
Co-founder & CEO · Benchmark
The audit identified six friction points in our onboarding flow we'd stopped noticing. The deck he delivered was the cleanest piece of UX work I've seen in five years of leading product — prioritized by impact, easy to defend in a leadership meeting, and immediately actionable.
