Learning
  - Technical
      - Use stderr and stdout properly (60% content for this 5w1h) (why do we need stderr, redirection, identify)
      - Use feature toggles
      - Write modular code in pkg dir so that anybody can import and use it (Eg helm, kubectl)
      - Easy dev setup (Makefile)
      - Logging at different log level (--debug flag)
      - 12 factor app (file, env, flag)
      - hyperfine for benchmark
  - NonTechnical
