About Me

With over 15 years of experience across diverse software environments—including startups, public companies, and non-primary software organizations—I have honed my adaptability and gained valuable insights into varied business challenges.

I specialize in enhancing developer productivity by creating tools that streamline engineering workflows and building resilient platform infrastructure.
