In Q1 2026, our 12-person backend team completed a 14-month rewrite of a 512,000-line Java 17 monolith to Go 1.25, cutting production deployment time from 42 minutes to 16 minutes (62% reduction) and reducing monthly AWS EC2 spend by $27,400. We didn’t cut features, we cut bloat: the Go codebase is 187,000 lines, 63% smaller than the original Java, with zero regressions in functionality. Every core service meets or exceeds our latency SLAs, and we’ve eliminated 3 dedicated CI/CD runners that previously sat idle 40% of the time. This isn’t a toy project: the monolith processes 14 million requests per day across 18 core services, with 99.99% uptime for the past 6 months post-migration.
