Writing about development and technology.
A practical guide to building streaming AI chat in Next.js with the Vercel AI SDK. Covers useChat, Server Actions, switching providers, tool integration, and handling loading and error states with real code.
Three core patterns that show up repeatedly in AI agent systems—Tool Use, ReAct, and Chain of Thought—explained with real TypeScript code. Understanding these patterns makes agent design significantly clearer.
Integrating Stripe for my SaaS was nerve-wracking. Code that handles money feels different. From Checkout Sessions to Webhooks—lessons from the trenches.
Beyond basic prompting — how to get reliably structured output from LLMs. System/user/assistant role design, few-shot examples, chain-of-thought, JSON mode, function calling, and building type-safe LLM responses with Zod and the AI SDK.
I needed real-time notifications and dove into WebSockets. From HTTP polling to Supabase Realtime—practical patterns for real-time communication.
LLMs don't know what they weren't trained on. Here's how RAG fixes that — walking through the complete pipeline from document ingestion to chunking, embedding, vector storage, retrieval, and generation with real Python and TypeScript examples.
Once you ship a public API, you can't change it freely. Compare four versioning strategies for evolving APIs without breaking clients, plus analysis of real-world choices by GitHub, Stripe, and Twilio.
I was manually cleaning data every day. How I set up cron jobs and background tasks in a serverless environment to automate the boring stuff.
I was running a service with zero insight into user behavior. Setting up PostHog changed how I make product decisions—from guessing to knowing.
As a single model grows complex, reads and writes start tripping each other up. Here's how CQRS solves that problem — from simple separation to full event sourcing, with TypeScript examples throughout.
Managing payment flow state with if-statements and boolean flags led to bug hell. XState's state machines made impossible states truly impossible.
Why does 'tech debt' make non-developer managers glaze over? Learn how to translate technical debt into business language, frame refactoring as investment, present to stakeholders with real metrics, and use prioritization frameworks that actually get buy-in.
I needed to send signup confirmation emails but HTML email development is hell. React Email lets you build emails like components, and Resend handles delivery.
Explore how Zod schema validation and tRPC solve the pain of REST APIs with manual types. Covers router setup, client-side type inference, error handling with Zod, migrating from REST, and when tRPC is and isn't the right tool.
Explore why synchronous request-response communication breaks down in microservices and how Event-Driven Architecture solves it. Covers Kafka vs RabbitMQ vs SQS, domain events vs integration events, event sourcing basics, eventual consistency, and practical Node.js examples.
I couldn't understand my own API after 3 months. Practical REST API design patterns for naming, versioning, pagination, and error handling.
Hexagonal Architecture isolates your business logic from the outside world using Ports and Adapters. Learn how to invert dependency direction so your core domain stays untouched regardless of what database, framework, or external service you swap in — with TypeScript examples throughout.
Every REST API I built had type mismatches between frontend and backend. tRPC eliminated the gap entirely—no API specs, no codegen, just types that flow.
I tried navigating my own service with just a keyboard and tab focus jumped everywhere. What I learned fixing accessibility issues in practice.
Applying Uncle Bob's Clean Architecture directly to frontend creates unnecessary complexity. Here's a practical, frontend-adapted layering strategy that actually works in production.
