    Adrian K. Agency Contractor

    Senior Web Developer / Project Manager

    United Kingdom - Last active: 2 days ago - Tests: 1 - Portfolio: 10

    If you have a project you think I can help with, I'd love to hear from you. I am native UK based web developer, with huge range of software engineering experience and an honours degree in Accountancy (from the School of Information Systems). While I love working with new technologies, I don't believe in technology for its own sake but rather I look to build solutions that are designed to meet your "real world" needs. What's more, I speak plain English! Not pigeon or geek speak. Oh, and if you're in the area, you are always welcome to pop in and have a cup of tea and a chocolate biscuit. What more could you want! Seriously though... I have developed over 100 websites over the past decade from small static sites to complex custom cms driven websites, newsletter management systems, ticketing and booking systems, e-commerce websites, holiday letting websites and even journey planning websites. While running my own software development company, I have worked for individuals, charities, schools, local and national government, as well as companies large and small. For those that are interested in the technical side of things, I am a "full stack" developer, equally happy working as a front end or back end web developer. I have managed, and continue to manage, small teams of developers and freelancers: I have commissioned over 30,000 hours worth of development time on Upwork alone. As you can hopefully see, I am "senior developer" with a great deal of experience (unlike many who claim this status on Upwork) and can turn my hand to most things. On the web development front, I have a high level of expertise with: * php * sql / mysql / postgresql * javascript / jquery * html / css / bootstrap and have also worked with web apps and responsive/mobile first designs. My projects are usually managed in a git repository with unit tests and a whole host of QA and continuous integration tools. Typically, I deploy and manage my own linux servers. While I usually build custom solutions, I am also happy to work with and recommend a wide range of open source solutions. I have developed sites with most of the major php platforms but particularly enjoy Wordpress and Magento. On the business side - in addition to my degree in Accountancy - I have considerable search engine marketing and optimisation experience working. Not only can I build search engine friendly websites but can also develop a strategic long term plan for your online presence - to make sure you're taking the right approach in the first instance or to help identify if you need a change of direction. In an SEO capacity, have worked with small charities to e-commerce sites with seven figure turnovers, managing PPC, on-site optimisation, and online marketing activities to provide high quality traffic, create and improve conversions and customer engagement, and ultimately to deliver profitable sales. Central to everything that I do is your customer's experience and your organisation's needs. Why not take a look at my portfolio to get a feel for the breadth and depth of my experience?
