PROFILE
Erick Rocha
Over four months, contributed to the NangoHQ/nango repository by building and enhancing billing, telemetry, and data transfer metering systems. Developed self-service invoicing updates and improved plan upgrade error handling, increasing billing accuracy and reducing support needs. Implemented transport-layer metering for proxy and webhook data transfers, integrating metrics with ClickHouse and Orb for observability and billing readiness. Strengthened telemetry by persisting runner data, tracking API egress, and wiring Pub/Sub batch publishing. Optimized scheduler performance by reducing unnecessary database roundtrips. Worked across the stack using TypeScript, Node.js, SQL, and backend development skills, with a focus on reliability, data integrity, and maintainability.

Jul 1, 2026July 2026: Delivered telemetry-enabled data transfer metrics ingestion and improved scheduler efficiency for Nango. Implemented egress byte metering, billing export ingestion with ClickHouse aggregates, and data transfer ingestion to Orb. Introduced isSchedulable guard to prevent unnecessary DB roundtrips, reducing load on actions, webhooks, and on-event handlers. All changes include updated tests and clear documentation of business value and performance gains.

May 1, 2026May 2026 monthly summary for NangoHQ/nango focused on expanding observability and reliability for data transfer metering and header correctness. Implemented transport-layer metering for proxy requests and webhook deliveries, with per-hop and cross-hop byte accounting and emission of observable metrics. Extended metering to server-forward deliveries and across redirects. Fixed content-length handling after decompression to prevent hangs and ensure correct lengths for uncompressed attachments. Set the stage for billing accuracy and data-driven capacity planning with observability integrations.

Apr 1, 2026April 2026 – NangoHQ/nango: Key features delivered and major fixes across Billing & Invoicing and Plan Upgrades, with a focus on business value and reliability. Key features delivered: - Billing and Invoicing Enhancements: Implemented self-service invoicing detail updates in the UI with backend support; upgrade invoices are marked as paid on pending plan changes to improve billing accuracy. Commits: 64965bd48d071474975faf1ac2a7bd125100cc4c; 1c599a41e078d581b793946ace49cfce545bcb0c. - Plan Upgrade Error Handling Improvements: Clear inline error messages and improved loading states for plan upgrade attempts; standardized error handling across billing flows. Commit: 2c0765ef10a60d0a00f3b423d65d4cf35dc8779c. Major bugs fixed (and quality improvements): - Upgrade invoices correctly marked as paid (not always credited) during pending plan changes, fixing base-fee vs prorated billing discrepancies. Commit: 1c599a41e078d581b793946ace49cfce545bcb0c. - Enhanced error feedback during plan upgrades: non-transient, inline errors with proper data refresh on retry, reducing user confusion and improving recovery. Commit: 2c0765ef10a60d0a00f3b423d65d4cf35dc8779c. Overall impact and accomplishments: - Business value: Reduced support workload via self-service invoicing, improved revenue recognition and billing accuracy during plan changes, and a smoother customer experience during upgrades. - Technical: End-to-end delivery across UI and backend, stronger data integrity between plan changes and invoicing, and robust, user-friendly error handling. Technologies/skills demonstrated: - Full-stack development across billing workflows (UI forms, backend invoicing logic, payment-state synchronization), improved error handling patterns, and cross-service data consistency with Orb for invoice settlement and plan-change processing.
