Cell-Based Architecture: Failure Isolation, Blast Radius Reduction, and Multi-Cell Routing at Scale
A practical guide to cell-based architecture: how to size cells, build routing layers, handle cross-cell data, deploy safely across cells, and decide whether the operational complexity is justified for your scale.
Designing a Calendar and Scheduling System: Availability Windows, Timezone Handling, and Recurring Events at Scale
A deep-dive into the backend architecture of a calendar and scheduling system. Covers data modeling for events and attendees, UTC-first timezone handling, RRULE-based recurrence, availability computation across multiple calendars, double-booking prevention, CalDAV sync, and scaling to millions of calendars.
Designing a Real-Time Feed System: Fan-Out Strategies, Activity Streams, and Personalized Timelines at Scale
How to architect a feed and timeline system from first principles. Covers fan-out-on-write vs fan-out-on-read tradeoffs, hybrid approaches for high-follower accounts, activity stream storage with denormalization, ranking and personalization layers, real-time push with WebSockets and SSE, cursor-based pagination, and cache warming strategies with TypeScript examples throughout.
Designing a WebRTC Backend: Signaling Servers, TURN Relays, and Scalable Peer Connection Management
WebRTC moves media between browsers without a server in the middle, but the backend infrastructure that makes it work reliably at scale is non-trivial. This covers signaling architecture, STUN/TURN deployment, SFU vs MCU topologies, room state machines, and fallback strategies.
Backend for Frontend Pattern: API Composition, Client-Specific Endpoints, and Reducing Frontend Complexity
A production guide to the BFF pattern: when to introduce a dedicated backend layer per client, how to implement one with Hono on Cloudflare Workers, where GraphQL fits versus REST, authentication forwarding, caching strategies, and the real operational cost of maintaining multiple BFFs.
Svelte 5 and SvelteKit in Production: Runes, Server Loading, and When to Choose Svelte Over React
Svelte 5 ships a new reactivity model built on runes, and SvelteKit's server-first loading story has matured. This is a practical guide for teams deciding whether SvelteKit belongs in production over Next.js App Router in 2026.
LangGraph in Production: Stateful Agent Graphs, Conditional Edges, and Checkpointing for Reliable Multi-Step AI Workflows
A deep dive into LangGraph for TypeScript: StateGraph concepts, conditional routing, checkpointing, persistence backends, streaming, error recovery, and honest tradeoffs versus simpler alternatives.
LLM Prompt Caching in Production: Prefix Caching, KV Cache Reuse, and Cost-Latency Optimization at Scale
Prompt caching and semantic caching are not the same thing. This guide covers inference-layer KV cache reuse: how it works in transformers, vendor-specific APIs (Anthropic, OpenAI, Gemini), stable prefix design, multi-tenant cache key composition, hit rate monitoring, and the real cost economics. TypeScript throughout.
Vector Search at the Edge: Building Low-Latency RAG with Cloudflare Vectorize, Workers AI, and D1
A practical guide to building a complete retrieval-augmented generation pipeline on Cloudflare's edge platform, covering document ingestion, vector index management with Vectorize, metadata storage in D1, embedding and inference with Workers AI, and the real latency and cost characteristics you should expect.
Automated TLS Certificate Management: ACME Protocol, Let's Encrypt, and Certificate Rotation in Production
A practical guide to automating TLS certificate lifecycle in production: ACME protocol flow, HTTP-01 vs DNS-01 challenges, cert-manager in Kubernetes, Caddy automatic HTTPS, Cloudflare edge certificates, rotation strategies, expiry monitoring, and the failure modes that will actually bite you.
Progressive Delivery with Argo Rollouts: Canary Analysis, Automated Blue-Green, and Metrics-Driven Deployment Gates in Kubernetes
A production playbook for Argo Rollouts: canary traffic shaping, blue-green automation, AnalysisTemplate wiring, rollback behavior, and when you need a service mesh versus simple weighted routing.
Wide Events and Observability 2.0: Why Structured Events Are Replacing the Three-Pillar Model
The metrics/logs/traces model is expensive, correlation-hostile, and cardinality-limited. Wide events, one rich structured event per unit of work, fix all three problems. This guide covers schema design, TypeScript emission with OpenTelemetry, column store analytics, and a practical migration strategy.
