Bio
Peter Campton
Simeon is a skilled software engineer with excellent knowledge of python and django. I worked closely with Simeon at Rangespan for 18 months and during this time he was a valued member of the development team, helping deliver important functionality to both internal and external users. Simeon was quick to learn and able to understand and develop functionality across the many systems at Rangespan. His code was well-structured, tested and he was able to both accept and provide valuable feedback during code-reviews. It was a pleasure working with Simeon and I would recommend him.

Simeon is a great addition to a software development team. He is diligent in his work and contributions, and clear in his communication with developers and non-developers alike. He is highly reliable, and tops this all off by being curious and knowledgable about the tools of his trade. If you want to work with someone who can get things done and is also a pleasure to have around, Simeon's your guy!
