• My name is Suharyadi, a backend / full‑stack developer based in Batam, Indonesia.
• Most of my time is spent on the backend: designing reliable APIs, setting up solid logging, and improving observability so production issues are easier to track down.
• Outside of work, I like experimenting with side projects and writing short technical notes on Dev.to to document what I am learning.
