Summary of non-technical differentiators
(… or “what I bring beyond my technical expertise“)
- First-principles learning for transferability of skills — When I learn something new, I try to also understand the underlying principles (i.e., the whys and the hows) instead of just rote memorisation. This allows me to transfer the skills that I learned to other technologies and even other disciplines.
- Leadership skills — Not just in terms of being a team leader, but mostly about being able to step up and take charge of a crucial situation when nobody else is doing so.
- Human integration — I can bridge the gap between diverse individuals by being able to put myself in the shoes of both business and technical stakeholders. I can understand their [usually] differing motivations and objectives, and then translate those into words that can make sense for everyone.
- Awareness of tech news and current events — Technology is developing in a fast pace, so it’s important to be up-to-date while maintaining a critical eye. This is also important for my role to make sure that I’m updated with discoveries of new security vulnerabilities.
- Team-level and even cross-team improvements — Beyond improving my own productivity, I also try to cascade these improvements to my team, and if possible, also to other teams. I do this by:
- Sharing knowledge and other learnings either by active teaching, writing documentation, or sometimes as simple as sharing links to important news and current events
- Making things easy by either formally automating existing processes or as simple as sharing my own scripts that help me in my day-to-day work
