How I Built a Programmatic Video Engine for SaaS Product Demos
Every SaaS product needs a demo video. The standard options are screen recording, which looks amateur and breaks every time the UI changes, or hiring a motion designer, which costs thousands of dollars and takes weeks. Both produce a static artifact that is outdated the moment you ship a new feature.I needed a product walkthrough for SampleHQ. Instead of choosing between those two bad options, I built a third: a React-based framework that generates cinematic demo videos programmatically. The res

5 JavaScript Mistakes Beginners Still Make in 2026
The Persistent Perils: 5 JavaScript Mistakes Beginners (Still) Make in 2026Alright, grab a coffee. We need to talk.It’s 2026. We've got async/await, Optional Chaining, Nullish Coalescing, Top-level await, even Stage 3 Record & Tuple proposals potentially landing soon. Our tooling is slick, frameworks are mature, and TypeScript has become the undisputed champion of type safety. Yet, I've found, working with teams both big and small, that some fundamental JavaScript mistakes still sneak
Is practical React + TypeScript still a realistic path for 2026/2027?

Stop Prop Drilling: Why I’m Moving Towards Atomic Component Design in React
Lessons learned on keeping React components clean, reusable, and maintainable in 2026. tags: react, javascript, webdev, architectureAs developers, we often start projects by throwing everything into one big component. It works at first, but as the app grows, you find yourself passing props down 5 levels deep. This is Prop Drilling, and it's a productivity killer. Here is how I’ve started restructuring my React apps for better scalability. 🏗️ The "Atomic" ApproachI’ve started breaking m
I built Mimik: an open-source Chrome extension that auto-captures browser workflows into step-by-step guides

You get a clean guide with one stepper action and an annotated screenshot per step. ✨ Features🎥 Auto-capture clicks, typing, and SPA navigation - one step per intent🤖 Optional AI step descriptio

BentoS3: a lightweight S3-compatible server for local development and tests
I recently published the first stable version of BentoS3, a lightweight S3-compatible server for local development, automated tests, and CI environments.The project came from a practical need. In our local environment, we were using MinIO as an S3 replacement. It worked, but we were still pinned to an old version, before the project direction changed and several features were removed from the free version UI and now the project is no longer maintained. That made the local setup feel more fragile
Building Simple Tabs with Vanilla JavaScript
Tabs are one of those UI patterns you see everywhere — dashboards, settings pages, pricing sections, docs, etc.In this post, we’ll build a fully working tab system using only HTML, CSS, and JavaScript. HTML StructureThe HTML Structure is minimalistic:<div class="tabbed-content"> <ul class="tabs" role="tablist"> <li role="tab" aria-selected="true" class="active">Tab 1</li> <li role="tab" aria-selected="false">Tab 2</li> <li role="tab" aria-sel
The Real Cost of UI Components in 2026
# The Real Cost of UI Components in 2026Modern frontend apps are far more component-heavy than they used to be.Dashboards, grids, charts, design systems, modals, nested layouts — everything is a component now.The problem is that not all JavaScript frameworks scale the same way as component counts grow.Virtual DOM systems improved UI development massively, but large component trees can still introduce rendering overhead, memory pressure, and unnecessary execution in complex applications.That’s wh

Let me be upfront about something, I made every single mistake on this list. Some of them multiple times. One of them I made in a codebase that was actually live and serving real users, which was a fun afternoon of emergency debugging.This isn't a "beginners are bad" post. It's more of a "here's the stuff that tripped me up and still trips people up, even when they feel like they should know better" post.
