Node.js + TypeScript: Building a Production REST API from Scratch in 2026
A complete guide to building a production-ready REST API with Node.js and TypeScript - authentication, validation, error handling, rate limiting, logging, and deployment. No shortcuts.
PostgreSQL Performance Optimization: The Practical Guide for 2026
Slow queries, missing indexes, N+1 problems, and connection pool exhaustion account for 90% of PostgreSQL performance issues. Here's how to diagnose and fix each one with real queries.
Building a Multi-Tenant SaaS with Next.js and PostgreSQL in 2026
Multi-tenancy is the architecture decision that determines how your SaaS scales. Database-per-tenant, schema-per-tenant, or row-level isolation - here's when to use each and how to implement it.
Clean Architecture in Node.js: A Practical Guide Without the Academic Fluff
Clean Architecture sounds great in theory. In practice, most implementations add complexity without benefit. This guide shows the pattern that actually works in Node.js - dependency inversion, use cases, and repository pattern with real, runnable code.
Redis Data Structures in Production: Beyond SET and GET
Most teams use Redis as a glorified hash map. This guide covers the data structures that solve real production problems - sorted sets for leaderboards, streams for durable event queues, HyperLogLog for UV counting at scale, and Lua scripts for atomic operations you can't otherwise do safely.
tRPC + Zod: End-to-End Type Safety Without Code Generation
tRPC eliminates the REST+OpenAPI codegen ceremony by making your server the source of truth for types. Here's a complete, production-realistic implementation - auth middleware, CRUD procedures, React Query integration, and the edge cases nobody mentions.
The Architecture of Resilience: Why We Abandoned 2018's Best Practices for 2026's Performance
In 2018, the industry optimized for code consistency and global state. In 2026, professional agencies optimize for data locality and the 'Cost of Change'. Here is why we transitioned from building features to architecting long-term resilience.
Microservices vs Monolith: The Real Guide for 2026
When microservices actually make sense, when a monolith is the right call, and the hybrid approaches most successful products use. Based on real-world tradeoffs.
GraphQL vs REST API in 2026: A Practical Guide to Choosing the Right Approach
GraphQL has been 'the future of APIs' for almost a decade. REST has been 'dying' for just as long. Both are still widely used in 2026 - because they solve different problems. Here's a practical framework for choosing, with real tradeoffs from production systems.
15 Years in Tech: What Building Apps in 2010-2014 Still Teaches Us Today
We spent 2010-2014 navigating PhoneGap, Node.js 0.6, Backbone.js, Hadoop clusters, and Bootstrap grids. Most of that stack is gone. But the reasoning behind those choices - the tradeoffs, the failure modes, the architecture instincts - still shows up in every project we build in 2025.
Bun: SQLite and the Power of Zero-Overhead FFI (2023)
Bun isn't just a fast runtime; its native SQLite implementation and FFI are changing how we think about Node.js performance in 2023.
Bun: How Zig and JavaScriptCore are Changing the Runtime Game (2023)
Node.js and Deno have a new competitor. In 2023, Bun 1.0 is here, and it's fast. Let's dive into the internals of the Zig-powered runtime.
