What I do
I design experiences as intuitive to use as they are beautiful to see, and the design systems that keep them consistent. Right now I’m with the Revox team; that’s me at my desk, click to say hello.

“Lahiru and I worked together for six months in the same team. During this time, I have gotten to know him as a creative and skilled UX designer who was an invaluable asset on all projects our team worked on. From small graphics to large and detailed web pages, Lahiru always delivered great and timely work with lots of attention to detail. I would recommend Lahiru to anyone seeking a creative UX designer to join their team.”

Selected work
SaaS, banking and language learning. The ones under NDA need a password; ask me and I’ll share it.
B2B SaaS, design lead
Building a payroll application for accountancy firms that is locally compliant with Sri Lankan labour laws and taxes.
Edtech, under NDA
Designing a language-learning app from scratch, grounded in how people actually learn and what keeps them coming back.
Fintech, mobile
Redesigning Sri Lanka’s leading mobile banking experience for simplicity and trust.
Edtech, iOS and web
Ink.ai brings parents, teachers and students together with a news feed, an AI-assisted editor and built-in video meetings.
Website redesign, work in progress
Redesigning the domain-selling website of a leading domain wholesaler to lift engagement and simplify the experience.
What I focus on
Good products feel calm because the decisions underneath them are consistent. I spend most of my energy on the system, so every screen built on it starts out accessible and on-brand.
Main focus
The craft I most want to master. I build foundations, tokens and components that let teams ship consistent, accessible UI faster, like the Humanised system I built from scratch. Try its primary button.
Built in, not bolted on
I check contrast, focus order and screen-reader flow while I design, not after. Currently learning with Intopia. Drag to see where text stops passing.
Your pay run is ready to review.

End to end
Discovery, flows, prototypes and testing with real users. Mostly SaaS products, websites and iOS apps across fintech, HR & payroll and edtech.
Reading list
Articles I’ve read and think are worth following if you design for learning.
Burr Settles & Brendan Meeder, Duolingo, ACL 2016
How Duolingo predicts when you’re about to forget a word, and what that means for designing practice schedules, progress meters and feedback.
Recall chance halves every half-life: p = 2^(−Δ/h). Duolingo’s skill strength bars are this number. Drag to watch a word go stale.
What I take into designShow progress honestly: strength should decay when practice stops, not stay gold forever.
Practising manteau (coat):
Pimsleur reviews every word on the same timetable. Leitner adapts, doubling the gap when you’re right and halving it when you’re wrong. HLR learns these weights from data instead.
What I take into designPersonalise practice: an easy cognate and a tricky word shouldn’t share one schedule.
Harder, decays fasterEasier, lasts longer
The model learned a weight for each word. Cognates and short, common words last longer; irregular forms, participles and rare words fade faster.
What I take into designContent design matters: the hardest grammar needs more frequent, better-explained practice.
Prediction error (MAE), lower is better
Daily retention after switching to HLR without word tags
HLR cut prediction error well below every baseline. A later version without per-word weights fixed words that decayed unfairly fast, and lifted daily retention.
What I take into designTrust is UX: when students said meters felt wrong, fixing the model brought them back.

I’m currently working with the Revox team. My experience spans fintech, HR & payroll and education, from Seylan Bank’s mobile app to Humanised’s payroll platform and Accented AI’s personalised language learning.
I specialise in SaaS products, websites and iOS apps, with design systems as the area I most want to master. Alongside work I’m learning accessibility with Intopia, design systems through Dan Mall’s Design System University, and code to bridge design and development. This site is part of that.
I love working with teams to turn creative ideas into intuitive, useful products.
