Projects that solve real problems

About Me

Designing for the moments
that matter in finance

I'm Lekha Mer — a fintech product designer based in Bangalore, focused on designing financial products that help people make better decisions.

I focus exclusively on fintech because financial products carry real stakes. A confusing interface costs someone their savings. A missing risk signal costs someone their trust. Bad UX in finance isn't just frustrating — it's harmful.

"Great fintech design makes the right decision feel obvious at the right moment."

My background in Finance and Marketing gives me business context most designers lack — I understand why products are built, not just how they look. Through simulations with Lloyds Banking Group, BCG X and bp × Jio, I've practiced the full research-to-design cycle.

I'm actively looking for junior roles and internships in fintech product design in Bangalore.

Background
Finance + Design thinking
A BBA in Marketing & Finance combined with UX design — a rare combination that brings real business context into every design decision.
Currently learning
Advanced interaction design & research
Deepening skills in usability testing, advanced Figma prototyping, and fintech-specific design patterns.
Design philosophy
Make the safe path the easy path
Good fintech design doesn't just inform users — it guides them toward better decisions by default, before they even realise it.
