API and webhook reliability QA builder from India.

I help teams test and harden workflow integrations: reproduce failures, check validation and duplicate handling, verify retries and logs, and document expected versus actual behaviour. My work is built with JavaScript/Node.js, REST APIs, webhooks, and safe synthetic data.

Open to hourly API/webhook QA work: 10–20 hours per week, 6 PM–3 AM IST, starting at US$15/hour.

• API Contract Drift Monitor — deterministic OpenAPI comparison that flags breaking changes and blocks CI with a non-zero exit code.
• LeadOps Intake & Triage — webhook intake with validation, deduplication, routing, retries, audit logs, and human review.
• Event Reliability Lab — HMAC validation, idempotency, bounded retries, dead-letter handling, traceable routing, and an independent heartbeat watchdog for stale or empty runs. v1.1.2
• Safe Data Preview — local JSON sanitization before sharing data with AI tools or collaborators.
• Minecraft Config Auditor — read-only configuration checks with explainable findings and synthetic fixtures.

All projects are personal open-source demos. They use synthetic data and do not represent paid client work.

The projects are small by design: each one has runnable examples, tests, and documented limits instead of production claims.

These are real local runs from the personal demos, not generated client proof.

Hourly or contract work testing and hardening API/webhook workflows. I’m comfortable documenting edge cases, expected versus actual behaviour, and clear reproduction steps.
