Cutting MapUp's Europe API Latency by 88%

Manish joined MapUp's backend team and found that API response times in the Europe region were running at around 25 seconds, well beyond acceptable thresholds and causing consistent timeout errors for users.

He diagnosed the root causes across the stack, identifying where latency was accumulating and what infrastructure changes would have the most impact. The work required understanding both the application layer and the geographic distribution of the system.

He brought response times down from 25 seconds to 3–4 seconds, an 88% improvement, significantly reducing timeout errors and improving the experience for European users. The fix was production-grade and measurable.
