Request path and middleware
We trace authentication, validation, and error handling from the first middleware through to the response serializer, noting where failures leak stack traces or skip audit logs.

Your Node.js backend, reviewed before the next release window closes
We read production services line by line—routing layers, database access, queue handlers, and test gaps—then hand you a prioritised refactoring brief your team can execute without guesswork.
What we examine
Reviews grounded in how your service actually runs
Data access and transactions
ORM queries, raw SQL, and migration history are checked for N+1 patterns, missing indexes, and partial rollback behaviour under concurrent load.
Background jobs and observability
Worker retries, idempotency keys, and log correlation IDs are reviewed so on-call engineers can follow a failed payout or import without spelunking.
Primary consultation
Backend Code Review Pass
A fixed-scope review of one repository (or a clearly bounded monorepo package) up to roughly 25,000 lines of application code. You receive a written report, a 90-minute walkthrough call, and a ranked backlog of refactoring tasks with effort notes.
Typical clients are CTOs and lead engineers at South African fintech, logistics, and B2B SaaS companies running Node 18+ on AWS or Azure.
Request a review slot“The report called out our duplicate idempotency checks in the webhook handler—something three of us had walked past. We fixed it before a partner load test.” — Lerato M., engineering lead, Johannesburg payments startup
