Insights & Writing
Curated technical articles on backend architecture, system design, modern fullstack development, and production engineering practices.
Learn how to architect ultra-low-latency real-time APIs that handle 100k+ concurrent connections. We compare WebSockets vs SSE, implement horizontal scaling with Redis Pub/Sub, and cover connection pooling, backpressure, and graceful degradation.
A deep dive into building production-grade RAG pipelines using PostgreSQL: combining dense embeddings with BM25 full-text search, implementing Reciprocal Rank Fusion, and leveraging context caching to reduce latency and cost. Includes a complete SQL/TypeScript implementation and performance trade-offs.
A deep dive into building ultra-low latency real-time APIs that handle over 100,000 concurrent connections. Learn to choose between WebSockets and SSE, horizontally scale with Redis Pub/Sub, and implement production-grade connection management and backoff strategies.
Learn how to build real-time generative interfaces with Next.js 15 App Router, React 19, and the Vercel AI SDK. This guide covers streaming LLM responses, Server Components, optimistic updates, and Server Actions for interactive tool components.
Learn how to build a production-grade AI code review pipeline in GitHub Actions using AST analysis, diff filtering, token budgeting, and strict prompt sandboxing to catch bugs and streamline PR reviews.
Learn how to architect real-time APIs for 100k+ concurrent connections using WebSockets, SSE, and Redis Pub/Sub. This guide covers horizontal scaling, connection pooling, backpressure, and graceful degradation with production-grade Node.js examples.
