Portfolio
Whilst I specialise in "back end coding" and have worked under various NDAs, it can be tricky to show my previous work. But I hope this selected portfolio will give you an idea of what I can offer you.
Q3 2019-Q1 2020
System Architect/Developer: Confidential Medical Records System
For a market leading UK insurance company, I developed a system using PHP 7.4, Slim Framework, Bootstrap Templates, jQuery, Datatables, JSON:API, MariaDb, Docker, Twig, Swiftmailer, PHPUnit, PHP-DI, ElasticSearch and AWS to offer a high availability, secure medical records system. Allowing login either via Microsoft Azure, Email/password, smart-card or "Web Authentication" (all with optional two-factor checks either via TOTP, SMS, email or telephone), this system was capable of handling over 30 million customers (with over 300 million records tested) with confidential information such as personal names, addresses, dates of birth, telephone numbers and medical records (all of which was encrypted) whilst still allowing easy billing, quick and simple data entry, fast searching (even on encrypted data), import of data from an external database, export of "usage" to Excel, CSV and HTML outputs - all whilst on a "Small" Amazon instance with less than 1Gb memory!
Q1 2017-Q1 2019
Developer: Web Quality Assurance Toolkit
Silktide Ltd
Using a combination of NodeJS, PHP 7, Silex Framework and Chromium, I developed a tool to capture screenshots of web pages, emulate user interactions (such as scrolling, key presses and mouse interactions), capture all assets transferred, check image compression sizes, check accessibility and have all the data returned to a PHP backend. I also created a web page to PDF conversion API to host on AWS, improved the speed of their spell checking system from around 30s per web page to less than 0.3seconds - along with more than doubling the size of their dictionaries, and also a JSON driven 2D graphics manipulation toolkit in PHP7 using Slim and Imagick and a domain name valuation tool tracking 219 million domain names.
Q2 2014-Q3 2015
System Architect/Lead Developer/Interim CTO: Online user verification video service
Comprobo Ltd
Using PHP 7, C++, ffmpeg, dlib (Machine Learning library), oAuth, jQuery, REST APIs, and JWT orientated microservices, I built a system to take biometric pictures of users (and compare those to that on record automatically for identify verification), playback videos (whilst recording user interactions), prompt for questions before, after and during video playback, creation of audit trails, log emails sent by the system (including timestamps from mail hand overs/bouncebacks) and integration with the TAO Testing platform.
Q4 2013-Q2 2014
WordPress Developer and Server Administrator
Marshall Design Consultants Ltd t/a Un.titled
Working for this Leicester based design agency, I built a tool to enable mass importation of products from multiple Excel spreadsheets into multiple WordPress websites (based on specific criteria, language settings and also product image availability). I also developed a Magento count down sales timer, a fully redundant Varnish-cached backed AWS powered Magento architecture, and a custom mailing list capturing software suite.
Q3 2008-Q4 2011
Lead Developer/System Architect: Online educational maths games
Blue Duck Education Ltd t/a Mangahigh.com
Working with Zend Framework 1, PHP5, jQuery, MySQL, CSS, HTML, AMF, Memcache and Varnish reverse proxy (and Linux), I created the bulk of the backend code for this new e-learning games orientated website - which encompassed integration with Paypal, Payvision, Bibit, XML and AMF integration - along with server admnistration/setup/monitoring work.
