Hi, I'm a full-stack developer. I design and develop web-apps and websites. I have 24 years experience of working with markup, styling, scripting, data, vector graphics, animations and developing apps using client-side and server-side technologies:

• Modern Javascript / ES2015+ (Front-End Development)
• PHP7 (Server Side Development)
• .htaccess (Server Configuration)
• CSS3
• HTML5
• SVG
• JSON
• Regular Expressions
• WebComponents
• IndexedDB
• Progressive Web App (Webmanifest & Service Worker)
• Web Storage (localStorage & sessionStorage)
• Javascript (ES5 / ES3)
• a dash of jQuery

In mid-2022, I'm now learning Deno, TypeScript and Vue 3.

Markup and Development

HTML5: I am familiar with working with a large number of HTML5 APIs, not least:

• Web Storage (localStorage & sessionStorage)
• IndexedDB
• Fetch (next gen xmlHttpRequest)
• Touch Events
• GeoLocation
• Web Workers (for multi-threaded development)
• Media API (Video & Audio)
• Page Visibility
• File System

Styling

CSS3: I am familiar with working with a large number of CSS3 Modules, not least:

• CSS Custom Properties
• CSS Grid
• CSS Flexbox
• CSS Typed Object Model
• CSS Animations & Transitions
• CSS Transforms
• CSS Filters
• CSS Masking and Clipping
• CSS Pseudo-Classes & Pseudo-Elements
• CSS Counters
• CSS Fonts
• CSS Columns
• Media Queries

I have 18 years experience writing CSS Stylesheets and presenting cross-device compatible web pages using Responsive Web Design, Adaptive Web Design, RESS etc.

Scripting and more (Server Side and Client Side)

Javascript: I have 8 years experience in writing ES5 and 4 years experience in writing ES2015+.

JSON: I can quickly and competently write and edit valid JSON and manipulate in both Javascript and PHP. In 2019, I wrote a single-page Javascript app presenting a user-interface for quickly creating valid JSON strings of any length and complexity.

PHP5 and .htaccess: I have 10 years experience in server-side scripting using PHP and server configuration using .htaccess (mod_rewrite, setting HTTP headers etc.) .

Ajax and Fetch API: I am adept in using Ajax to asynchronously access server side scripts from the client side. I am increasing my competency in using the Fetch API (the ES2015 next generation alternative to Ajax / xmlHttpRequest).

Regular Expressions: I frequently use Regex in javascript, PHP & .htaccess.

Website Maintenance: I am familiar with robots.txt and XML Sitemaps. In 2014 I wrote a PHP app which auto-generates XML Sitemaps.

jQuery: When I need to do so, I can quickly and competently translate backwards and forwards between jQuery and Javascript.
