Mantas Kemėšius

Based in Vilnius, Lithuania. I work as a Senior Software Engineer at HomeToGo, Europe's largest marketplace for vacation rentals.

Working software is the baseline now. What sets a product apart is how it feels, and that comes down to taste and a lot of small decisions. That's the part I enjoy most: design systems that keep things consistent, interactions tuned until nobody notices them, and motion with a reason behind it. Lately I spend a lot of time making AI better at this kind of work, teaching agents the patterns behind good interfaces so building them gets faster without losing the details.

In 2025 I also became an indie hacker, building small profitable products in my free time: Bodly, a health tracker for iPhone, Toonio, an app that turns photos into cartoons, and VendorJot, which helps contractors collect documents from their vendors. They're also how I learn the business side of software: finding users, reading the numbers, and turning an idea into something people pay for.
