A little about how I work

I'm Alex, an engineer who cares about the details that users never see but always feel — response times, clean data models, and code that the next person can read. I focus on TypeScript, Go, and cloud infrastructure, and I'm happiest turning fuzzy requirements into systems that stay reliable under real-world load.
