Worked on the iptv-org/database repository to enhance reliability and maintainability of data ingestion workflows. Developed an asynchronous logo URL validation system using Node.js and JavaScript, featuring a bounded worker pool, retry logic, and image-type verification to ensure brand assets are accurate and accessible. Introduced robust per-domain rate limiting and backoff strategies to handle HTTP 429 responses, reducing concurrency and adding delays to stabilize external requests. Standardized CSV parsing across the ingestion layer by integrating the csvtojson library, replacing custom parsing logic. These improvements collectively reduced operational risk, improved data quality, and streamlined support for downstream systems relying on accurate assets.

Mar 1, 2026March 2026 monthly summary for iptv-org/database focusing on reliability, data quality, and maintainability. Highlights include: (1) Logo Validation Improvements: implemented an asynchronous logo URL checker with a bounded worker pool, retries, and image-type verification; HEAD fallback to GET on 405; 429 retry scheduling with exponential backoff; per-request throttling; and progress metrics. Commit references: aaf4265f659b5c6437c17954ca7faaba01ab1456 (Add logo URL checker script), e44ebfa1b1a4125defa45b42d1ba0b7fe9266f20 (Replace magic-byte detection with probe-image-size), 52e4d2af058fa5edd17f7bcab7b72cf88c93783d (Add tests for check_logos script). (2) Robust External Request Throttling and Rate Limiting: introduced per-domain rate-limit backoff for HTTP 429, applying Retry-After to all pending requests for the domain; reduced DEFAULT_CONCURRENCY from 50 to 10 and set DEFAULT_DELAY_MS to 200ms to avoid rate-limit spikes. Commit: 290f3e741cd1267524c577e5544ded7adb3525a3, ad6e1c26778ab66a4476a803590c757d781f9361. (3) CSV Parsing Standardization: replaced a hand-rolled CSV parser with the repository-wide csvtojson library for consistency and maintainability. Commit: 93f874ac455b43963787e6e1face777958551d46. Overall impact: improved data quality and trust in logos, reduced data ingestion failures due to bad or mis-typed logos, greater stability under rate limits, and streamlined ingestion pipelines. The changes collectively lower operational risk while increasing throughput under compliant usage patterns. Technologies/skills demonstrated: Node.js 18+, asynchronous worker pools, robust HTTP retry/backoff strategies, per-domain rate limiting, protocol-aware HTTP handling (HEAD/GET fallbacks), integration of csvtojson, and test-driven validation via script tests. Business value: higher reliability of brand assets in downstream systems, lower support overhead from broken logos, and safer scaling of data ingestion workflows.
