Why products stall

Great products lose customers to confusing design.

Most SaaS and FinTech products don't fail on technology. They fail when users can't see the value fast enough.

01

Users sign up, get confused, and leave.

What it costs you

You pay to acquire users who never reach the "aha" moment, so activation and revenue stay flat.

How I fix it

I map the path to your users' first win, simplify every step, and test it with real people before a line of code is written.

02

Your product looks less credible than it is.

What it costs you

Buyers and investors judge a dated interface as a weak team, even when the technology behind it is strong.

How I fix it

A modern UI and a scalable design system that make your product look as premium as it performs, and stay consistent as you grow.

03

What ships doesn't match the design.

What it costs you

Developers guess, deadlines slip, and the details that made the design work get lost in handoff.

How I fix it

I design and build, so one person owns the result from Figma to production and nothing gets lost in between.

About me

A note before we work together

I'm a product designer. I help SaaS and FinTech teams turn complex ideas into products people understand in seconds and enjoy coming back to.

My job is to find out what your users actually need, then design the flows, interface and design system that get them there. I test with real people before anything is built, so you ship what works, not what we guessed.

I started in brand and visual design. Nine years and 300+ brands taught me that the screens that move numbers are never the prettiest ones, they're the clearest. And because I also build front ends, the design you approve is exactly what goes live.

You work with me directly and see real progress every week. If you're building something people should enjoy using, I'd like to hear about it.

FAQ

Questions clients ask first

Straight answers on process, payments and ownership.

01What happens after I pay?

You get a receipt straight away and a kickoff email from me within 24 hours with a short questionnaire and a link to book our kickoff call. Work starts within 5 working days.

02Which time zones do you work with?

I'm based in Dhaka (GMT+6) and work with clients in the UK, Europe, the US, Canada, Australia and Dubai. I keep at least 3 hours of overlap with your working day for calls and quick decisions.

03How many revisions are included?

Project work includes 3 revision rounds per phase. Hourly blocks and retainers are flexible: you can use the time on revisions or new work.

04Who owns the designs and code?

You do. Full ownership of all files, designs and code transfers to you on final payment. I'm happy to sign your NDA before we start.

05Do you only design, or build too?

Both. I take products from research and flows to a finished UI and design system, then build the front end in React/Next.js, Framer or Webflow. If you have your own developers, I hand off clean, build-ready Figma files instead.

06How do payments work?

Hourly blocks and retainers are paid upfront. Projects are split 50% to start and 50% on delivery. If we stop early, unused hours are refunded.
