Mahdi Osati
Front End Engineer
I build accessible, pixel-perfect digital experiences for the web.
ABOUT
I’m a frontend engineer with a specialty in web accessibility,
focused on building pixel-perfect, intuitive user interfaces. I
enjoy working at the intersection of design and engineering, where
great user experience meets robust, clean, and scalable code.
Currently, I'm a senior frontend engineer at Klaviyo, where I work
on the component library team to help maintain and evolve our design
system. In this role, I lead accessibility efforts across
components,
tooling, and patterns, partnering closely with designers and
engineers to ensure accessibility is part of our core architecture.
Previously, I’ve worked across a wide range of environments, from
product studios to startups and large tech companies, including
Apple, Starry Internet, and Upstatement. Alongside my professional
work,
I also created an online video course a few years ago which walks
through building a real-world, API-driven application from scratch.
These experiences have shaped how I think about building products
that are both well-crafted and widely usable. Outside of work, you
can usually find me climbing, playing tennis, hanging out with my
wife and two cats, or running around Hyrule searching for Korok
