Experience

Telenor Connexion

https://www.telenorconnexion.com/
Telenor is the biggest provider of telecom, data, and media communication services based in Sweden.

I worked with a Telenor Group site called Telenor Connexion. This site focuses on IoT and related fields. My work included implementing the design updates in accordance with the new company rules.

Caveon | Test Security Solutions and Software

https://www.caveon.com/
I built a WordPress website from scratch using the Elementor builder plugin. Also, I developed custom Elementor widgets and blocks with rich functionality and customization ability to fit design requirements.

Froda Loan Calculator

http://froda.se/
Froda is a digital corporate credit company based in Sweden.

I developed a loan calculator on the front page. It was built from a client's Excel application. I also implemented some Excel financial functions in JavaScript like PMT and IPMT. It was also built with SCSS, native JavaScript, and HTML.

Full-stack Development Work at Open Homes

https://www.open-homes.com/
I participated in the development and redesign of an internal CRM system, which involved integrating APIs and working with Laravel and Vue.js. I also worked on a WordPress marketing website and developed some custom plugins that have integration with the Laravel back end.

Good To Great Schools Australia

https://www.goodtogreatschools.org.au/
Good To Great Schools Australia (GGSA) required a robust, scalable platform to deliver complex educational content. The existing WordPress monolithic structure was limited in performance and flexibility.

I led the migration to a Next.js front end, using WordPress strictly as a headless CMS and LMS data source via REST/GraphQL APIs. This allowed for a highly customized, app-like user interface that remains lightning-fast even under heavy traffic. To solve the challenge of user fragmentation, I integrated Auth0, providing teachers and administrators with a secure, unified login experience. By implementing rigorous CI/CD workflows, I empowered the team to ship features faster and with greater confidence, ensuring that the platform’s uptime remained high for the thousands of students relying on it.

Backyard Design

https://backyarddesignusa.com/
Backyard Design is a global leader in custom motocross graphics, but their success created a technical bottleneck: their monolithic WordPress setup struggled with the complexity of custom design data.

I was brought in to transform their digital infrastructure into a "headless-first" production powerhouse. I redesigned the order management flow to handle intricate product variations and built custom integrations with Google Sheets and Drive. This turned a manual file-handling process into an automated pipeline, where customer designs are instantly synced to the production team’s cloud folders. To future-proof their operations, I developed a standalone Print Product Management System using Symfony for the heavy backend logic and Next.js for a lightning-fast admin dashboard. This decoupled system communicates with WordPress via a custom-built REST API, allowing the staff to manage thousands of custom prints without ever slowing down the customer’s shopping experience.
