Technical Decision Records: How to Make Decisions That Stick
Most engineering teams make important technical decisions in Slack threads or someone's head. When that context disappears, the same debates repeat. This covers what ADRs are, a practical template, when to write one vs when it's overhead, and how they change team dynamics around disagreement and ownership.
Distributed Cron Jobs at Scale: Designing Reliable Schedulers for Multi-Region Systems
A practical system design guide to building distributed cron infrastructure, covering clock skew, leader election, sharding strategies, exactly-once versus at-least-once execution, idempotency, retries, backpressure, and multi-region failover.
Distributed Locks with Redis: Preventing Double Processing in Job Workers
A practical guide to designing distributed locks with Redis for background jobs, including failure modes, lock renewal, fencing tokens, and production-ready TypeScript implementation patterns.
Event-Driven SaaS with the Outbox Pattern: Reliable Events Without Dual Writes
Publishing domain events directly from app code often causes lost messages and inconsistent state. Learn how to implement the outbox pattern in a SaaS architecture with practical TypeScript examples, delivery workers, retries, and observability.
How Caching Works: Strategies, Patterns, and Pitfalls for Production Systems
Cache-aside, read-through, write-behind, stampede prevention, TTL tuning, and the invalidation problem explained with TypeScript examples and honest tradeoffs. A practical guide to distributed caching in production.
Pragmatic Service Decomposition: When and How to Split Your Monolith
A senior engineer's guide to service decomposition that starts with the real question: should you split at all? Covers concrete extraction signals, boundary identification techniques, data ownership strategies, and incremental migration patterns with TypeScript examples.
The Service Decomposition Playbook: Extracting Services Without Breaking Production
A step-by-step execution guide for extracting services from a running monolith. Covers dependency mapping, API contract design, dual-write migration, traffic cutover patterns, rollback planning, and operational readiness checklists with TypeScript examples.
Authentication Patterns for Modern Web Apps: Sessions, JWTs, and When to Use Each
Most tutorials pick JWTs or sessions without explaining the tradeoffs. This covers stateful sessions with Redis, stateless JWTs, refresh token rotation, OAuth 2.0 integration, CSRF and XSS attack surfaces per approach, httpOnly cookie handling in Next.js and Hono, and a decision framework based on real architecture constraints.
AWS Lambda vs Cloudflare Workers: Architecture, Cost, and When to Migrate
A deep technical comparison of AWS Lambda and Cloudflare Workers covering execution models, cold start characteristics, real-world pricing at scale, ecosystem differences, and concrete migration patterns with TypeScript code and a decision framework.
Designing Webhooks That Scale: Delivery Guarantees, Retry Logic, and Security
Fire-and-forget HTTP POSTs break under real load. This guide covers the full architecture of a production webhook system, from event generation through fan-out delivery, with TypeScript examples for HMAC signing, exponential backoff, idempotency, and thundering-herd mitigation.
How to Evaluate LLM Output Quality in Production
A practical framework for evaluating LLM output quality in production, including offline test sets, online metrics, LLM-as-judge caveats, human review loops, guardrails, and release gates that prevent silent regressions.
Vector Databases Compared: What to Use and When
Choosing a vector database is less about benchmark charts and more about retrieval quality, metadata filtering, operations overhead, and cost predictability. This guide compares Pinecone, Weaviate, Qdrant, pgvector, and Milvus with concrete decision rules for real production workloads.
