Software Developer

I build web products end to end — the interface, the API, and the data underneath them.

About

I build software end to end — interface, API, data — and I care about the parts nobody sees as much as the parts they do.

My approach:

I'm a software developer who enjoys building things end-to-end. From UI to backend, I like writing clean readable code and solving real problems. Always learning, always improving. Day to day that means React and Next.js on the front, Node and Postgres behind it, and a bias toward code the next person can read. I test the flows that matter, document the components other people reuse, and keep an eye on what the bundle costs.

Why React Context and State Stores Behave Differently When Rendering Components

If you’ve spent time in React, you’ve probably noticed a recurring claim: Context causes unnecessary re-renders, while libraries like Redux, Zustand, Jotai, or MobX feel more optimized.

Understanding SSR, CSR, Server Components, and Client Components in Next.js (The Right Way)

Modern Next.js has fundamentally changed how we build React applications. If you learned React through traditional single-page apps (SPAs), concepts like Server Components, hydration, “use client”, and the mix of SSR and CSR can feel confusing and overlapping.
