Software craftsman - Rails, React and Typescript enthusiast.

I'm Sev, a software engineer based in London. I love building meaninful products that make a difference.

I'm Sev Osmanko. Welcome to my corner of the internet.

I'm a seasoned software engineer with a passion for transforming complex problems into elegant, user-friendly solutions. Over the years, Ive had the incredible opportunity to work with some of the most innovative companies out there, including Monday.com, Shopify, Growth Intelligence, and MRI Software.

My experience in the world of Software has been varied. From developing dynamic form builders and expanding web crawling capabilities to leading global software deployments and mentoring junior developers, I've worn quite a few hats. But no matter the project or role, my goal is always the same: to create tech that makes people's lives better and more enjoyable.

When I'm not immersed in lines of code, you can often find me exploring the great outdoors, losing at chess, or down at the pub. I'm always up for a chat, so feel free to reach out if you want to talk tech, share a pint, or just say hello.
