Why Every Dev Should Build a Pomodoro Timer

Every developer hits a point where they need a quick side project to sharpen their skills. The Pomodoro timer is one of the best beginner-to-intermediate projects you can build.

Why a Timer?

A timer seems trivial but it forces you to deal with:

• State management — tracking whether the timer is running, paused, or stopped
• Intervals — understanding setInterval and cleanup to avoid memory leaks
• UI updates — re-rendering efficiently as the clock ticks down
• User experience — notifications, sounds, visual cues

What I Built

I added a fully functional Pomodoro timer to my portfolio. It has three modes:

1. Pomodoro (25 minutes) — deep work sessions
2. Short Break (5 minutes) — quick rest
3. Long Break (15 minutes) — recharge after a few cycles

The whole thing is a single React component with useState and useEffect. No external libraries needed.

Takeaway

The simplest projects are often the most rewarding. You get a usable tool AND a portfolio piece. Go build one — you can find mine on my projects page.
