Alexander Shafir is a Software Architect and Engineering Lead at Protego Trust. He possess expertise in embedded systems, embedded software, c, cloud computing, c++ and 35 more skills. Colleagues describe him as "Alexander held an incredibly challenging role to maintain quality and safety-critical design constraints for a large, complex, and novel software ecosystem. His role within the team was vital for the challenging build -- where he was the most active reviewer of pull requests. On top of this, he was also a top code contributor. Alexander was a software engineering mentor for the team, and frequently made himself available to review other people's code, architect solutions, and demonstrate software engineering patterns. He drove a number of weekly software engineering meetings and held the team to high standards. He also interfaced with a number of teams where his depth of knowledge was an organization-wide resource. Culturally, he reinforced a safety-critical design mindset and kept the line for code quality. Akin to sports -- a referee is often vital, underappreciated, and the subject of debate. Alexander stepped-up to this role at the request of peers, and took-on a tremendous amount of responsibility on behalf of the team. The team values Alexander as a deeply trusted and respected colleague. I personally observed his skill-set spanning a variety of domains where he was proficient at the most expert levels. It is a privilege to work closely with Alexander, and I hope to have the opportunity again."
