How gRPC Works: Protocol Buffers, HTTP/2 Streaming, and Production Patterns in TypeScript
A deep dive into how gRPC actually works: Protocol Buffer encoding and schema evolution, the four RPC communication patterns, HTTP/2 multiplexing mechanics, interceptors, deadline propagation, load balancing with gRPC, the health checking protocol, and when to reach for gRPC over REST or GraphQL. TypeScript examples using @grpc/grpc-js and connect-es.
How the V8 JavaScript Engine Works: Parsing, Compilation, Garbage Collection, and Why Your Node.js Server Pauses
A deep dive into V8's internal architecture for senior Node.js engineers: the parsing pipeline, Ignition bytecode interpreter, TurboFan optimizing compiler, speculative optimization and deoptimization, hidden classes, inline caches, and the generational garbage collector behind every GC pause.
How HTTP/2 and HTTP/3 Work: Multiplexing, QUIC, and the Protocol Upgrades Behind Modern Web Performance
A deep dive into the protocol evolution from HTTP/1.1 to HTTP/2 to HTTP/3. Covers binary framing, multiplexed streams, HPACK compression, QUIC over UDP, 0-RTT handshakes, connection migration, and production deployment patterns for CDN and edge delivery.
How the Node.js Event Loop Actually Works: Phases, Microtasks, and Production Implications
A deep dive into the six phases of the Node.js event loop, the microtask queue, how I/O interacts with the poll phase, and what all of this means for production TypeScript applications.
Frontend Observability in Production: Real User Monitoring, Error Tracking, and Performance Instrumentation with OpenTelemetry
Most teams have solid backend observability but no visibility into what users actually experience in the browser. This guide covers Real User Monitoring with Core Web Vitals, client-side error tracking with source map resolution, distributed tracing via OpenTelemetry JS SDK, and a build-vs-buy comparison for frontend observability tooling.
Building AI-Powered User Interfaces in React: Streaming Responses, Tool Call Rendering, and Progressive Enhancement with the Vercel AI SDK
A production-focused guide to building AI chat and copilot interfaces in React. Covers streaming token rendering with useChat and useCompletion, real-time tool call rendering, message persistence, progressive enhancement when AI is unavailable, and performance patterns for high-frequency re-renders.
Designing APIs for AI Agent Consumption: Structured Actions, Self-Describing Responses, and Tool-Friendly Patterns in TypeScript
AI agents are now first-class API consumers. This guide covers the patterns that make APIs consumable by LLM-powered agents: structured action endpoints, self-describing responses, deterministic pagination, error messages that enable self-correction, and production considerations for rate limiting, auth, and observability when agents are your primary API consumer.
Testing Architecture for TypeScript Backends: Unit Tests, Integration Tests, and a Testing Strategy That Actually Scales
A practical guide to testing TypeScript backends at scale: revisiting the testing pyramid, unit testing with Vitest and dependency injection, real integration tests with Testcontainers, and the tradeoffs between mocking and integration approaches that shape a testing strategy that survives a growing codebase.
GDPR Engineering for SaaS Teams: Consent Management, Data Subject Requests, and Privacy-by-Design Architecture
The engineering patterns behind GDPR compliance for SaaS products: consent storage and versioning, DSAR automation pipelines, right-to-erasure cascades, Article 30 records, and privacy-by-design architecture in TypeScript.
Implementing Enterprise SSO for Your SaaS: SAML, OIDC, SCIM, and Directory Sync for Multi-Tenant Applications
A complete engineering guide to SAML 2.0 SP-initiated and IdP-initiated flows, OIDC for enterprise, SCIM 2.0 directory sync, multi-tenant identity routing, and production considerations including certificate rotation and just-in-time provisioning.
From No-Code to Production Code: A Technical Migration Guide for Founders Who've Outgrown Bubble, Webflow, and Glide
A practical guide for founders hitting the ceiling on Bubble, Webflow, or Glide. Covers the signals that tell you it's time to migrate, how to pick a production stack, how to move your data without downtime, and a realistic timeline and budget framework for the rewrite.
Why Your Vibe-Coded MVP Starts Breaking at 60 Days: Security Patterns, Architecture Fixes, and a Production Readiness Checklist
