Freelance Android App Developer

Android Developer UK

My name is Ollie Cornes and I am a freelance Android developer in the UK delivering services to clients remotely on an hourly basis from London (SE1). I specialise in smaller Android developer projects, Android app maintenance and ad-hoc work usually for startups and small businesses in the UK and abroad.

As an experienced and passionate UK Android freelancer, I’m committed to delivering high-quality work for my Android project clients. I collaborate with companies, agencies and individuals on a flexible basis, working closely with each client to understand exactly what they need from an Android developer.

I have worked as an Android developer in the UK since 2010, in the past using Java but now Kotlin.

Get in touch today so we can start on your next Android project. A comprehensive CV is available on request listing my freelance Android developer experience.

Android App Development

As a UK Android developer I can build your Android app from scratch working alongside you and other developers (e.g. iOS) and designers. My services are customised to meet the specific needs of each client. I work collaboratively throughout the entire process. Contact me to find out how I can help today.

Android App Maintenance

Do you have an existing Android smartphone app that needs ad-hoc Android app maintenance, or incremental improvements and bug fixes over time? If so please contact me as I am ideally suited to this type of work and just charge for each hour of work performed with no commitment.

Android App Review 

If you want to have a free of charge discussion about an existing or possible future Android app project, or to discuss your options for how to move ahead, please contact me.

Terms and Costs

I specialise in shorter projects ranging from a single day to a few weeks in duration. I can create a new app for you, or maintain, fix or improve an existing app. The rate for each day’s work (seven hours of work) is £450/USD560 which is £65/USD80 per hour.

Permanent roles, long-term full-time projects, profit-share and equity-share will not be considered. Please note that all work is performed remotely (from my home office), but I am easily contactable via Slack, Skype, Zoom, email, phone etc. No agencies, please.

I do not build iPhone apps as I am an Android specialist but if you need an Android app and also an iPhone iOS app I can refer you to an experienced iOS freelancer.
Terms of business: Work is billed on an time basis (in fifteen-minute increments) with no minimum monthly billing. At the end of each week, an invoice is issued for work done during that week. The invoice is due to be paid on receipt. Work the following week will continue once the previous week’s invoice has been settled. Invoices that remain unpaid after seven days incur additional fees. Clients are always in control of their costs.
