About
I'm Md. Tanvir Ahmed. I have direct experience with the WordPress.org theme review process, resolving feedback on coding standards and best practices, giving me a solid grasp of production-grade development. My approach emphasizes precision: scoping changes tightly, debugging to root cause, and verifying work before calling it done — reflecting readiness to contribute meaningfully from day one, with room to grow.

CDN For System Design: How Content Delivery Networks Work
A deep-dive walks through how content delivery networks work by following one photo file from upload to viral moment to privacy change, covering cache keys, TTL and eviction, tiered edge/regional/origin architecture, push vs pull models, anycast routing, TLS/QUIC handshakes, DDoS mitigation, edge compute, ESI-style hole-punching, microcaching benchmarks, multi-CDN tradeoffs, cache hit ratio vs origin offload, and signed URLs/cookies for private content. It frames these mechanics as answers to the four questions a system design interviewer asks after ‘add a CDN’: cache key, TTL expiry cost, edge selection, and serving private content publicly.
