Senior software engineer
$225.00/hr
I am a freelance software engineer specializing in mobile app and full-stack software development.
I have over 20 years of experience in professional software engineering. The last seven years of that has been working on web and mobile apps, their backends, cloud infrastructure, and devops.
I am available for short-term freelance software engineering contracts in web full-stack, mobile app, and cloud infrastructure development, using Swift, Kotlin, React, TypeScript, JavaScript, Python, Java, Erlang, OCaml, Objective-C, and C.
I work on multiple platforms including Docker, Amazon Web Services, Google Cloud, Linux and macOS.
I have used many database backends, including ElasticSearch, MySQL, and PostgreSQL.
I strongly prefer remote contracts, though I am open to work in the San Francisco area.
Before freelancing I was the chief architect and founder at Tipbit, an email, calendar, and contacts app for iPhone and iPad. I have previously held roles as architect and director for XenServer at XenSource and Citrix, and founding engineer and technical board member for OpenStack. In general I have been a software engineer in telco, virtualization and cloud since 1997.
I am a UK and US dual citizen. I have a degree in Computer Science from the University of Cambridge.
