Callum Wallach | Developer

About me

I'm an enthusiastic and dedicated software engineer with an extensive background in enterprise web design and development. Product-minded with a strong work ethic and an emphasis on sustainable development through collaboration, integrity, transparency and teamwork to produce high-quality, modular, well tested and maintainable code. I'm adept at applying design principles and following best practices and have a passion for debugging complex technical issues. I thrive in a diverse team environment and enjoy working remotely, independently and as part of a successful team.

Please view some of my projects below.

Projects

One of my proudest achievements outside of work was to contribute to the Project PoSSUM Scientist Astronaut Program investigating atmospheric climate change, which included training in zero gravity and high-g environments and culminated in being one of the world's first citizen scientists to test a commercial spacesuit in zero gravity!

I'm also passionate about travel, adventure, health & fitness and photography. I've explored some 70 countries and climbed, kayaked, cycled and ran on all 7 continents including Antarctica. I'm an experienced Land Search and Rescue first responder, have a background in the martial arts and co-own a boxing and fitness gym in New Zealand. I've also been fortunate to appear in a number of film and TV shows in stunt and acting roles.

Fully responsive React front end app with a JS, Node and Express backend connected to a Google Firebase DB. Data was graphed and displayed using HighCharts. Deployment was Dockerised to Render.
