I create quality software at an affordable price - Randall Toepfer, Freelancer

My Services

Engineering Applications

I have worked on several challenging projects in multiple engineering disciplines. I worked with multiple engineers and chemical scientists to create an environmental database used to calculate greenhouse gas emissions at over 15,000 oil and gas wells. I also worked with three-dimensional data on Android and VTK.

Cloud Applications

I have configured Salesforce.com instances and built applications on the Force.com API. I also have experience with Google Cloud and Google App Engine (see my first App Engine app here). I created mash ups with several cloud web service API's including the Google Drive SDK, Intuit QuickBooks SDK, and Amazon Web Services.

Web Development

I like to keep things simple and design web applications using modern design techniques and frameworks such as Django, Laravel and Bootstrap. By using these frameworks I am able to leverage the same code for web and mobile user interfaces. I've created applications that interface to large enterprise software systems.
