Freelance Back end developer in Glenwood, United States

Experienced Software architect and developer, helping to make complex apps easier to navigate

I am a senior software developer (full stack), mostly working in the web for the last 20 years (I started a bit before, but in and on and off basis). During the last years I've worked mostly in Ruby (Rails, Sinatra), which I enjoy. I am highly technical and pragmatic, but I believe I can communicate effectively with both technical and non technical management. I like to keep learning (a requirement for my job, in this always changing area) and incorporating new technologies and ideas in the software I produce. During the last years I've been the technical lead, and in the last 3 years the only Senior Engineer in my team, in a scientific organization connected with NASA.

Freelance Back end developer in Ashburn, United States

I write, nurture and love clean, testable architectures. Language doesn't matter. I eat two technology stacks and a Linux meal a day.

I write, nurture and love clean, testable architectures. Language doesn't matter (PHP/C/Rust/Golang/Typescript/Python/Java). I eat two technology stacks and a Linux meal a day. How is that possible? After 15 years of programming, you start to not be in love with your toys anymore like a kid, and treat them as tools instead. What starts to matter after reaching a certain level is expressing ideas with code, not the code itself. It's the ideas that you share with your collegues, as well with the machine, that solve real-world problems that matter. Tools are just that, and in our area of expertise, they change over time quite rapidly. What stays relatively constant are the terminology, the algorithms, and the train of thoughts for solving a specific problem, given a specific scenario.
