01 · Context

What needed to change

Contact access is part of the core messaging experience. Repeated API operations were adding load and making lookups slower than they needed to be.

02 · Challenge

The hard part

Improve the user-facing response time while reducing avoidable backend work across a busy production system.

03 · Approach

How I approached it

  1. Investigated the contact access path and identified redundant API operations.
  2. Changed the lookup flow to remove repeated work while preserving the response expected by callers.
  3. Checked the production impact through latency and daily operation counts.

04 · Outcome

What shipped

Made contact lookups 5× faster and eliminated more than 290,000 unnecessary API operations per day.
