Warren Fletcher

Bio

Warren started programming by making mods for The Elder Scrolls IV. While some of them did not result in a BSOD. Most did. This habit has not faded with time, and nor has their proclivity for tinkering/modding/breaking things.

Graduating from UCT with a degree in Electrical & Computer Engineering. Warren has worked for multiple Fortune 500 companies (Oracle, Amazon, Booking) in the Web-Scale space.

In 2023, they returned to South Africa from a stint in the Netherlands(It was too cold.) They wanted to get back into 'dirty' hands on engineering work. Currently, they now work at Hydrogen Energy Applications (HYENA) as a Staff Systems/Software Engineer building the future of stationary remote generators. These generators make use of Fuel Cells.

They are incredibly passionate about automation, electrical engineering, and empowering others to build software that is performant, scalable, practical and, above all, a 'joy to use'. No matter the customer.

In their free time(hah), They can be found playing guitar. He still cannot play wonderwall.
