Replatforming a B2B Marketplace
Took a seven-year-old monolith from weekly outages to daily deploys in six months — without pausing feature work.
- Deploy frequency: monthly → daily
- Infrastructure spend down 40%
- P1 incidents down 85% quarter-over-quarter
PLACEHOLDER CASE STUDY — replace with a real engagement before launch.
The Situation
A logistics marketplace was shipping slower every quarter. Seven years of growth had produced a monolith nobody fully understood, weekly production incidents, and an engineering team spending more time firefighting than building.
What I Did
As fractional CTO (two days/week, six months) I owned the technical strategy: stabilized the incident pipeline first, then carved the riskiest domains into independently deployable services — strangler-fig style, no big-bang rewrite. Rebuilt the hiring loop and brought on two senior engineers who now own the platform.
The Outcome
Daily deploys, an on-call rotation that actually sleeps, and a roadmap the board can read. The team kept shipping features the entire time.
