Case studies
These examples show the kind of contained backend and integration problems I have worked on. They intentionally avoid employer names, product names, code and confidential system details.
API latency reduction
Reduced a production API’s p99 latency from approximately 300 ms to under 120 ms by focusing on the request path, query shape and the parts of the application that were growing with traffic.
Credit ledger reliability
Designed a transaction-ledger workflow with idempotency, pessimistic locking, expiry handling and duplicate-redemption prevention so payment-adjacent state changes stayed consistent.
Offline analytics pipeline
Moved expensive runtime analytics into an offline computation and bulk-ingestion pipeline to reduce pressure on the live request path.
Release automation
Automated a repetitive multi-environment release process that previously took about 30 minutes of manual work, reducing friction during deployments.
