I've worked for a variety of companies, startups in silicon valley to defence companies in the UK.  From senior software engineer up to CTO level.  At all companies I've always been involved in day to day coding and for the last 10 years the majority of that coding has been in web technologies such as PHP.

I have built two side businesses focused upon WordPress plugins with a focus on plugins for small businesses and agencies.  One of these businesses was bought by a large competitor so I also understand business acquisition process.

I have written a book on how to create WordPress plugins which receives regular sales and good feedback.  I also have a course in development to teach developers how to create WordPress plugins.


Throughout my career and business in software engineering I have used many databases such as MySQL, PostgreSQL, SQL Server and Oracle.  I have written entire data layers and database abstration models and understand how to write complex SQL queries.
I've worked with extremely large data sets and high throughput systems and understand the challenges that can face relational databases.  I can design database schemas and normalize them sensibly.
