Bojan Rajkovic

Hi, I’m Bojan. I’m a technology generalist, with interest areas in engineering systems & culture, API design, and performance engineering.

Why should you hire me?

About Me

Broadly speaking, I’m T-shaped — I’m comfortable leading teams and managing people, diving into code (writing, reviewing, debugging, optimization, etc.), building infrastructure, working on engineering systems and culture, building software development lifecycle policy, structuring out knowledge management (ask me about why it’s key to healthy organizations!), and designing systems architectures. I’m a Git wizard, a comfortable and proficient technical writer, and I love to teach and mentor.

I’m comfortable learning on the fly — I firmly believe that for most engineers, the things you already know aren’t important, but your curiosity and learning/knowing how to learn are what will determine your success. I love building organizations and finding efficiences and economies of scale and structure that make collaboration easier; my teams are consistently highly engaged with their work, deeply care about their customers and products, and it shows in their outcomes.

If you’re a startup, I also bring experience in the business of startups — the team I led at Xamarin worked closely with finance, sales, and executive teams to devise and build new approaches to collating and understanding business data, and extract insights that correlated to how we built and shipped our software.
