Hello, I'm Josh, frontend developer. 👋

In 2021, after working in various industries, I decided on a career switch & fully dedicated my spare time to learning how to code.

I quickly found a strong passion for frontend development, which led me to pursue a career in it.

Two years later, I landed my first role as a frontend engineer and have since had the privilege of working on exciting applications with two amazing companies.

Recently, I’ve developed an interest in design and continue to expand my skills in that area, aiming to blend both design and development in my work moving forward.

I’m excited to keep learning and growing as I take on new challenges and explore new technologies.

In my spare time, I love working out, attending music festivals and playing football.

Contact

I’m currently looking for a new full-time position and open to exciting opportunities. If you have any interesting projects, or side projects you’re working on, feel free to reach out. I’m always happy to connect and collaborate.
