Case study · ShareDocView
ShareDocView.
DocSend-style document sharing, hardened as fractional CTO.
Document sharing with tracking and analytics. I joined as fractional CTO to take the production system from shipping-fast to shipping-safely without slowing the founder down.
01 / Role
What fractional CTO meant here.
I joined ShareDocView as fractional CTO once it was already live with paying customers. The founder needed senior engineering judgment without hiring a full-time CTO: architecture decisions, code reviews on critical paths, security pass before bigger contracts, build-vs-buy calls on third-party services.
My role is async-first with a weekly cadence and on-call for incidents. I work in the existing repo and infra, the founder keeps everything in his name.
02 / What changed
What I helped harden.
- · Authentication and session management hardened, audit-ready.
- · Document upload + viewer pipeline, with tighter access controls and tracking events.
- · Analytics layer, rebuilt for fewer queries and clearer per-document insight.
- · Observability: structured logging, error monitoring, uptime checks, alerting.
- · CI/CD pipeline tightened with environment promotion and rollback safety.
- · Cost and security pass on the cloud bill.
03 / Outcome
What it looks like today.
ShareDocView ships features faster because the dangerous parts (auth, billing, deploy) are no longer the things that wake the founder at night. The fractional model gives him a senior engineering brain on retainer without the cost or commitment of a full-time hire.
This is exactly what the Aftercare / Fractional CTO offer is built to deliver to other founders.
