Original resume problems

  • Bullets listed technologies but did not explain system scale, ownership, or tradeoffs.
  • Leadership contributions were hidden behind individual implementation details.
  • Reliability and performance improvements lacked concrete metrics.
  • The skills section was broad, making the strongest backend and cloud signals harder to scan.
