A selection of backend systems, developer tools, and product infrastructure I've shipped.

LedgerStream

Event-sourced ledger processing 40M transactions/day

Problem

The billing platform reconciled balances in nightly batches, so disputes took up to 24 hours to surface and finance had no real-time view of exposure.

IMPACT

Cut reconciliation latency from 24 hours to under 2 seconds and eliminated a class of double-charge incidents entirely.

Pulse CLI

Developer tool that surfaces service health from the terminal

Problem

On-call engineers context-switched between five dashboards to triage an incident, losing minutes that mattered during outages.

IMPACT

Reduced mean time to acknowledge by 35% by collapsing health, logs, and recent deploys into a single terminal view.
