About Me
I really like solving different problems that users have, those could be B2C web applications,
custom internal apps or developer tooling. Over time, I've learned the importance of balancing
challenging engineering tasks with simpler, faster decisions that meet business needs and allow
for progress. Additionally, I realized, that the value of the software engineer is not in being
the React Andy and knowing only one tool, but being able to figure stuff out even in an
environment where you have never been before. This includes taking on different roles within a
project, leading a team, engaging with the customers, knowing when to be the flag carrier and
making a decision, instead of having hours of discussions and landing on an unsatisfying
compromise.
My core value as an engineer is that I solve problems, no matter what they are.
