Charlie Hill

Programmer, Freelance Consultant

I enjoy solving social and business problems with creativity and technology. I take pride in my work, and I am constantly learning better ways to get things done. I enjoy working with smart, creative people who like what they do and are open to sharing their knowledge and ideas.

Open source

I first began programming as an open source contributor to the Simple Machines Forum software, developing a few different plug-ins, which are still being used to this day by hundreds of websites. I have continued to contribute to the open source community in the form of code, technical support, writing documentation, and have recently (early 2016) started organizing a programming meet-up in Prague.

Early professional career

During my professional career I've had the good fortune to be able to work on a wide variety of different projects with many nice, talented people. My first full-time position as a programmer was at a web agency in Chicago where I worked on a few different projects, one of which in particular was quite fun and challenging. I was tasked with integrating numerous third-party services, migrating existing systems, and developing a robust search solution.

Startup experience

In the spring of 2012, I agreed to join an education start-up with the goal of fixing the broken university-level textbook industry in the United States. There I was tasked with designing, developing, and maintaining a suite of products including an e-reader web application and e-commerce system.

Freelance consulting, personal projects

Since moving to Czech Republic (late 2013) I have been working as a freelance consultant. In addition to working on clients' projects, I am also developing a few of my own projects.

I might seem busy, but I am always open to hearing about interesting, new projects and welcome hearing about what you're building, too! So please get in touch.

Have a super day!
