The App Router is more than nested folders. Below are lesser-known patterns I use in real projects to compose UX, keep code maintainable, and ship fast. Use these as bite-sized recipes; each has a minimal example you can paste into a new Next.js app (App Router enabled). 1) Parallel
When building modern web applications, user experience is everything. A single broken button, a misaligned layout, or a failing API interaction can frustrate users and drive them away. That’s why frontend testing is no longer optional—it’s essential. In this article, we’ll break down what frontend testing
Authentication in the JavaScript ecosystem has been a patchwork for years: you either wire up lots of library glue or outsource to a SaaS and give up control. Better Auth flips that script. It’s framework‑agnostic, runs inside your app, keeps data in your DB, and ships a plugin
Modern users don’t wait. Performance is the product: it shapes SEO, conversions, retention, and how people feel about your brand. This playbook is a practical, copy‑pasteable guide to ship perceptibly faster apps in 2025—without rewriting your stack. Why performance is a business feature * Higher conversions: every 100ms
Front End
Performance and UX live and die on the client. Two small utilities—throttle and debounce—solve a surprising number of real-world problems: from taming noisy scroll/resize events to making type-ahead search feel instantaneous without DDoS-ing your backend. This post goes beyond one-liners and covers when to use each, solid
Architecture
In the world of software engineering, we often strive for perfection—zero downtime, flawless deployments, and always-on services. But reality has other plans. Networks fail, APIs go down, and sometimes, the unexpected happens. The question isn’t if your system will fail, but how it will behave when it does.
Infrastructure
Modern systems are like black boxes—complex, distributed, and full of moving parts. When something goes wrong, how do you know where and why? That’s where observability comes in. It’s not just about collecting logs; it’s about gaining real insight into your system’s behavior, so you
Architecture
In the world of distributed systems, failures are inevitable. Whether it's a network glitch, a slow downstream service, or a complete outage, resilient systems are designed to handle these failures gracefully. In this post, we'll explore three key patterns for building resilient systems: Circuit Breakers, Retries,
Understanding algorithm efficiency and performance analysis What is Big O Notation? Big O notation is a mathematical way to describe how the performance of an algorithm changes as the input size grows. Think of it as a report card for your code's efficiency - it tells you how
Front End
As a front-end developer, finding the right tools can make the difference between a good project and an exceptional one. Over time, I've discovered an incredible collection of resources that have transformed how I approach web development. Here's my curated list of 10 must-have front-end tools
Infrastructure
Terraform has become the go-to tool for infrastructure as code, allowing teams to define, provision, and manage cloud resources efficiently. In this tutorial, we’ll walk through configuring Terraform for AWS, covering workspaces, remote backends, modules, variables with validations, and .tfvars management. Prerequisites Before starting, ensure you have: * Terraform installed
Dev
Going from a junior developer to a senior isn’t just about writing more code — it’s about leveling up your skills, mindset, and perspective. Let’s break it down into a dynamic, easy-to-follow roadmap for 2025. 1. Nail the Basics Before anything else, your foundation has to be rock-solid:
