Freelance/contracting.

Working on their existing platform primarily in PHP (5, 7 and 8)) usingPostgreSQL as the primary database. Worked with various AWStechnologies including Lambda (NodeJS), CloudFormation, EC2, ECSAurora PostgreSQL, SNS, SES SQS, and API Gateway.Built an API and data dispatch system for integration with Festicket afterthe acquisition of the company using PHP (Slim) for the API as well asSNS->Lambda(Node)->SQS/HTTPS for data push.Worked on the Access Control System which ran on .net consisting of anAPI, web UI, Xamarin mobile app and also a Kotlin mobile app.

Returned to previous employer to continue work on the software previously written to help push it forward for release-to-market. Focus primarily on using a variety of programming languages and services to allow parallelisation of reports, data analysis and real-time graphing with reduced cost but also increased speed. For example using Amazon’s Lambda for the number crunching of data out of CouchDB into a pre-computed MySQL database to power an information website.

Software Engineer. Rewriting of current API’s to be simpler, cleaner and adhere more to SOLID as well as aiming for REST principles where currently there were very little. Use of Doctrine and some Symfony. Standardising the multiple modules currently in the systems into a coherent set of independent modules with easy data exchange between them.

Build distributed systems using PHP, MySQL and CouchDB across over 100 servers.

Focusing more on fully fledged programs built in PHP mostly for internal clients but including the occasional external (public) website. Heavily MVC orientated (including Zend Framework). Also implementation of other design patterns such as singletons (primarily used for PDO connections), factories (for the distributed job system), proxy classes (to enforce separation of data from code) and the observer pattern (to allow plugins to core system modules).Day-to-day administration of our 4 large MySQL servers and over 50 “worker” servers in various locations around the world. The worker servers run custom software I wrote in PHP to deal with jobs from a queuing system (customized beanstalkd) that now forms the core of the business and allows other developers to easily deploy new scripts that required large, distributed data processing: a system that allows easy horizontal scalability just by adding new servers.Set up and wrote map/reduce jobs running on our own 4TB CouchDB cluster to allow migration away from MySQL

Web developer, focused primarly on client websites (cut up's, Framework builds etc)

Office/phone work and setting up and managing the work network as well as helping staff with PC problems and creating the business website - www.shires-removals.co.uk . A highly varied role which includes the daily user support of office staff on PC's, support on bespoke software I wrote for the company and installation of new hardware among other tasks. The business website was created entirely by myself with almost all graphics created by myself also, everything was manually coded.
