Hello! I'm Zayin Krige


I have a love for development and have been coding for fun and professionally for 33 years. I started out with GWBasic(3 years) and have worked in Turbo Pascal (5 Years), ASM (2 Years), Delphi (7 Years), C/C++ (4 Years), Java (10 years), Kotlin (3 Years), Swift (5 Years), Objective-C (9 Years), Javascript (5 Years), PHP (6 Years), Python (2 Years), PERL (2 Years), Flutter (3 Years), Solidity (3 Years) and React Native (6 Years)

I have built numerous mobile apps for both iOS and Android, as well as cross platform apps using React Native and Flutter. I have built NodeJs backends hosted on AWS, and PHP/Laravel backends which are self hosted.

I have plenty of blockchain knowledge and have written a number of custom Ethereum based contracts for clients using Solidity et al.

I have a wide range of experience across many different development related fields and bring a vast depth of systems knowledge with me.

I have built systems using Interbase, Firebird Database, SQL Server, MySQL, CouchDB and DynamoDB on AWS.

I owned and sold a point of sale company that had installations across Southern Africa.

I co-founded a vending ( TopItUp ) startup in 2009 and sold my shares in 2013
