Karolis Zaksauskas | Front-End Developer

01 / About

A bit about me

I'm a Front-End Developer at Mission10, a digital agency in Aberdeen, where I serve as the sole front-end specialist across 40+ live client projects. I handle everything from initial architecture and build through to production deployment and ongoing maintenance.

My clients span Oil & Gas, property, legal, and energy sectors including names like Dolphin Drilling, Port of Aberdeen, Kirkwood Homes, and SES Energy. I've built full front-end systems from scratch, created reusable component libraries, and managed CMS and infrastructure upgrades across production environments with zero downtime.

Beyond the day-to-day, I've built custom performance plugins targeting Core Web Vitals, implemented structured data, Schema.org / JSON-LD markup, and Google AI schema for SEO, and established code quality standards with linting, testing, and pre-commit hooks across the agency.

I graduated from Robert Gordon University in 2024 with a BSc (Hons) in Computing. Originally from Lithuania and now based in Aberdeen, I speak both English and Lithuanian. I'm always exploring new tools and technologies to improve how I build things.
