About

I'm a software developer currently living in Ottawa with a broad skillset and an extensive knowledge of the structure of network infrastructure from the software side, including standards, protocols, and industry-standard software. Most of my personal projects are available on either my personal Git server, git.jules.ninja, or on my GitHub.

My fields of expertise are network programming, information security, and backend web development (including most things that would usually fall under DevOps), and I'm most comfortable working with Python, C, or Haskell in any of these areas.

I'm passionate about solving problems almost regardless of the technology I work with. I already know many different languages, libraries, and frameworks, and this allows me to approach problems from a number of different angles in order to develop the most efficient solution to many types of problems.

As of January 2018, I'm actively seeking work; ideally, I'm looking to move away from early-stage startups in favour of something more stable and long-term. Shoot me an email if you think I might be a good fit for a role at your company!

When I'm not working on programming projects, I'm cycling around Ottawa's fantastic bike-friendly roads, hiking in Gatineau park, or enjoying a cold one at one of Ottawa's many pubs and craft breweries.
