Building digital
experiences
that matter.
10+ years crafting products across B2B SaaS, payments, mobility, and retail tech. Rooted in user research. Driven by systems. Always asking why.
About
Hey, I'm Rezaur Rahman Shahed.
Ten years of building things
that actually work.
I started my career asking questions — sitting across from users, watching where they hesitated, listening for what they didn't say. That research instinct became the foundation of everything I build.
Today I work across web, POS, kiosk, mobile, and operational platforms in B2B SaaS. I think in systems, but I design for moments. I've shipped across prop-tech, payments, mobility, and retail tech — always with the same north star: does this make the person using it feel like it was made for them?
When I'm not shipping products, I'm somewhere with a camera and bad trail conditions, learning that the best view always requires a harder climb.

Work & Projects
Built and
shipped.
Checksy
I couldn't find what I needed, so I built it.
I couldn't find a to-do app that was fast and easy — one that just lived quietly in my browser without making me leave my tab or sign up for anything. So I built one, with the help of AI. Checksy is a distraction-free daily task list that resets every morning. Add tasks in seconds, check them off, and start each day with a clean slate. Nothing carries forward to clutter your day.

Philosophy & Process
“I believe the best products start with the hardest question: why does this need to exist at all?”
Research-first
Every good product decision traces back to a real human need. I don't skip the 'why' — I start with it. Research isn't a phase; it's a posture.
Systems thinker
I think in loops, not lists. The best products are coherent systems where every part knows why it exists and what it's connected to.
Human at center
At the end of every sprint, there's a person whose day gets better or worse depending on what we shipped. That's the work. Everything else is means.
AI as a thinking partner
I use AI to think faster, not think less. It's in how I brainstorm, synthesize research, and build. Checksy exists because I stopped waiting for the perfect tool and shipped one instead.

Writing
Ideas worth
writing down.
Things That Didn't Ship
I've also
failed well.
Not every bet pays off. Some ideas were right but early. Some were early and wrong. Some were wrong in ways that took years to fully appreciate. These are the ones I tried to build, couldn't get to fly, and learned the most from.
STORIES FROM THE ROAD
When I’m not building products, find me on a mountain.
Between the
mountains &
the maps.
Travel is where I think clearest — above the clouds, between bus rides, in places that don’t have names on maps yet.
Mentorship
Let's think
through this
together.
I mentor product managers and UX researchers — especially people navigating the early and mid-career transitions that felt genuinely confusing to me when I was in them.
We can talk about career direction, skill gaps, how to break into PM, how to do research that actually influences decisions, or how to handle the messy middle of a complex project.
