Projects

High-throughput systems, data pipelines, and performance-critical services I've built.

  • Sherlock

    High-throughput job data aggregation platform ingesting 15K+ records/day from 160+ independent sources using 20+ concurrent workers. Engineered content-hash deduplication eliminating 35% overlapping postings and built a relevance-ranking pipeline returning results in under 200ms. Built fault-tolerant ingestion with Redis-backed caching, per-source rate limiting, and exponential-backoff retries reducing redundant requests by 60% with 99% pipeline uptime.
