Technical Library & Architecture Papers
Deep-dive technical guides on distributed systems, database scaling, web performance, and modern infrastructure by Yash.
Distributed API Gateway Architecture: Rate Limiting & High-Throughput Ingress
Designing resilient API gateways using Redis sliding window algorithms, token bucket throttling, and circuit breakers for mission-critical microservices.
Serverless PostgreSQL Connection Pooling: PgBouncer, Hyperdrive & Neon at Scale
Architecting resilient connection pooling for ephemeral serverless functions, comparing PgBouncer transaction pooling with Cloudflare Hyperdrive and Supabase Supavisor.
Next.js App Router Caching: Deep Dive into Request Memoization, Data Cache & PPR
Understanding the four-tier caching system of Next.js App Router to avoid stale data bugs, optimize TTFB, and architect lightning-fast edge applications.
PostgreSQL Indexing & Query Optimization: B-Tree, GIN, BRIN and EXPLAIN Plans
Master PostgreSQL query performance: B-Tree internal anatomy, GIN vs GiST for JSONB, BRIN for time-series data, and tuning autovacuum for table bloat.
Distributed Locking & High-Concurrency Caching Patterns with Redis and Lua Scripts
Implementing distributed mutual exclusion using the Redlock algorithm, preventing cache stampedes with probabilistic early expiration, and atomic Lua scripting.
Zero-Trust Network Access (ZTNA) Architecture: Beyond Perimeter Security
Transitioning from legacy corporate VPNs to identity-aware proxies, mutual TLS (mTLS), and continuous context-based authorization across distributed teams.
Production Observability with Sentry: Distributed Tracing & Error Monitoring
A deep-dive technical blueprint for implementing real-time exception tracking, distributed transaction tracing, and privacy-first session replays across Next.js apps.
Kubernetes FinOps & Cloud Cost Governance: Resource Optimization at Scale
Implementing automated horizontal and vertical pod autoscaling, spot instance orchestration, and namespace-level chargebacks to cut cloud spend by 40%.
Edge Cloud & Modern CDN Architecture: Global Routing, Caching & Workers
Optimizing global content delivery networks, Anycast routing, stale-while-revalidate caching semantics, and running serverless compute on edge points of presence.
Zero-Downtime Database Migrations in High-Availability Distributed Systems
Executing non-blocking schema migrations on live relational databases using expand-contract patterns, dual-writing, and shadow table backfilling.
Enterprise Generative AI Security: DLP, Prompt Injection Defense & Privacy Guardrails
A comprehensive blueprint for securing enterprise LLM pipelines against prompt injection, model jailbreaking, training data exfiltration, and sensitive data leakage.
Enterprise Disaster Recovery: Active-Active Multi-Region Replication & Failover
Designing resilient disaster recovery topologies with sub-minute RTO and RPO across distributed cloud providers and geolocated availability zones.
