My career includes large organisations (Citi, Salesforce) and early to late stage startups within Fintech and Data Science companies. Most recently working with a Berlin Fintech startup as a Machine Learning Platform Architect, developing data transformation services as well as evolving organisational and engineering practices.

I am the founder of Practicalli which provides community educational resources for software engineering, with a focus on Clojure and common development tooling. The work is done in personal time and includes freely available videos and books on Clojure and ClojureScript development, guiding those interested in building services with the powerful, elegant and fun Clojure language.

I have invested time over the last decade to supporting people in the London developer community as well as many online communities. I have had the pleasure of organising many hundreds of events for the London Clojurians community. I've also helped run 12 ClojureBridge London events, supporting people from under-represented groups as they start their journey into the software industry.

In my spare time I love to cycle and in 2019 I cycled 1,000 miles (1,600km) across Britain in 9 days and raise thousands of pounds for charity.

Sponsor Practicalli

All sponsorship funds are used to support the continued development of Practicalli series of books and videos, although most work is done at personal cost and time.

Thanks to Cognitect, Nubank and a wide range of other sponsors from the Clojure community for your continued support
