Your Friendly AWS | Linux Guy

Romania - Tests: 5 - Portfolio: 2

With 15+ years experience in Linux maintenance and administration, excellent computer skills and a penchant for geeky projects, I am your best choice for a reliable and patient worker. I am an AWS Certified Solutions Architect and I can help you set up, configure, monitor and optimize your cloud infrastructure for a highly available and fault tolerant system on AWS. I hold degrees in linguistics and in neuroscience, meaning I am in touch with both the hard sciences and the humanities. Academic writing and formatting is almost second nature to me. I also have over 10 years of experience in literary and technical translations. I am diligent and I respect my deadlines, but perhaps the most important thing is that I take my work very seriously. No cutting corners or sloppy work.

Process-oriented Unix/Linux Developer

Canada - Tests: 3

I'm a process-oriented developer with a strong focus on Linux and Unix applications. My experience is varied from making cosmetic tweaks to various applications, to developing driver software for various hardware devices. I do also have a working understanding and experience with the windows environment. I do prefer to build long-term relationships with my clients, and do endeavor to be your go-to guy for software development and integration. It's very important to me to maintain a varied and multi-dimensional amount of experience. For this reason, I do prefer smaller projects over larger ones. I'm flexible with my working hours, and work out of a 24/7 co-working space. What this means for you, as the client, is I do not have the typical distractions of working from home. I am a very goal-oriented individual, and my biggest weakness is missing sleep when I'm presented with an exciting challenge to break through. I work on milestones, and one of my pet peeves is becoming disoriented on a challenge by leaving it half-done for the next day. I am also very, very keen on documentation! I spend a large amount of my time documenting proposed changes and integration drafts. I look forward to hearing from you!
