Vetted Java developer in the United States (UTC-5)

Over the last 15 years, I've worked as a teacher, a support engineer, a data engineer, and a software engineer. In all that time, the most engaging and satisfying work was always helping other people learn and overcome challenging issues. I have professional experience with the following languages/technologies: * Python * Java * Bash * Web (HTML, CSS, JavaScript/TypeScript) * SQL (multiple dialects) * Korn * Perl * C * Android * Docker * Linux * Git I've developed everything from simple scripts that automate repetitive tasks, to ETL pipelines, to full stack web applications (the API and backend services, as well as the HTML/CSS/JavaScript frontend), and along the way I've mentored engineers, students, and non-technical people wanting to level up their skills.

Brian S.

Vetted Java developer in Canada (UTC-5)

Software Architect with over 20 years developing Java applications. I am proficient in Spring Boot, Hibernate, Spring Security, Maven, etc. I have helped Java developers solve some of their most complex problems. I derive a great deal of satisfaction from coaching and mentoring other developers. Many people smarter than me have mentored me during my career, so I want to pay it forward. I love seeing how people use my teachings to solve ever more complicated problems, and to grow their own careers. I don't just teach people how to do something, but I also explain why. They can use this to inform their own judgment when they need to make similar decisions or solve similar problems in the future. The primary reason we write software is not for the computer, but for the people who have to read it and figure it out. The code must be clear and expressive; ideally it should read like prose to a software developer. To make systems easier to change, they must be modular, with clear separation of concerns, and it needs observe the principles and best practices of software design. It needs to handle errors and unusual situations gracefully, and provide clues as to what happened, and why it happened, and provide guidance on what to do next. This is the philosophy I bring to your teams and to you as a mentee.
