Case studies

Three pieces of work, each written as problem, decisions and result: a hotel PMS at scale and two personal PWAs whose code is public.

A hotel PMS: overbookings, releases and hardening
I traced overbookings to stale availability in the outbound channel sync, rebuilt the release pipeline from 30+ minutes to about 7, and ran a proactive security hardening program on a PMS used by +150 hotels.
