№ 03My process
From a messy problem to a measurable outcome.
For me, product design starts with two questions: what is the user struggling with, and what is it costing the business? I work with product managers, engineers and data from day one, explore widely, validate early with real users and ship in small steps we can measure. Every release should move a number that matters.
01
Problem Finding
User interviews, analytics and support tickets, until the real problem and its cost to the business are clear.
- Research insights
- Journey maps
- Opportunity sizing
02
Problem Framing
Narrow the findings to one problem worth solving, and agree the goal, metric and scope with product and engineering.
- Problem statement
- Success metrics
- Priorities
03
Solution Shaping
Explore several directions, prototype the strongest, test with real users and refine until it feels obvious and is buildable.
- User flows
- Prototypes
- Usability tests
04
Solution Pitching
Tell the story with prototypes and data so the team can decide, then hand off clear specs and measure the impact after launch.
- Stakeholder demos
- Specs & components
- Impact review
I design products for people who don't have time to learn them: shopkeepers settling the day's credit, customers paying from a bank app, analysts asking an AI for answers. Good design, to me, is when the next step feels obvious, however complex the system behind it.
Over eight years I've led product design from field research to launch: TallyKhata, the ledger 5.35 million shopkeepers signed up for, and a SureCash wallet redesign for 20 million customers at Progoti Systems. Most recently, at JustGo, I built and governed a tokenized design system across web and mobile. I also taught UX and research methods part-time at Shanto-Mariam University for five years, and mentor designers on ADPList.
Now based in Berlin and ready for a senior product design role, full-time or contract, on-site, hybrid or remote. I work in English and I'm learning German.
