Hello, I'm João Carreira

Freelance iOS and Web Developer

Hire me! How can I help?

What can I do?

Although focused on the iOS platform, my experience doesn’t end here, I can help developing your product to the web too!

iOS Apps

Having contributed to 7 published apps in the App Store, this is my main area of expertise, developing apps for the iPhone and iPad.

Web Frontend

Some app concepts work better as web apps and with a responsive design and mobile-first mindset I can turn your app idea into a functional cross-platform web app.

Web Backend

Modern apps rely on a backend server that feeds information to them. I can design, build and deploy an entire server system, from databases to web services.

About me

I’m an iOS and Web developer with more than 5 years of experience in the industry. I got my feet wet back in 2011, with iOS5, having worked as an iOS developer for different companies, in diverse business areas, contributing to industry-grade apps that you can still find in the App Store today.

How do I work

Fixed-cost projects or on-demand daily rates, either setup works for me

I’ll chop-down big projects into small tasks and provide accurate estimates so that you know how long something will likely take and cost

I work remotely but I’m based in Lisbon (Portugal)

During working time I’m always available via email, phone, Skype, Slack or other means of communication we agree on
