Milan katira About Projects Testimonials Contact

I'm a full-stack engineer with a passion for building performant, scalable, and elegant digital products. With 4+ years of experience, I specialize in creating AI-driven SaaS platforms, responsive user interfaces, and modern backend systems.

I work with React, TypeScript, Node.js, and scalable design systems to architect frontends and collaborate closely with backend and product teams. I've contributed to platforms serving 20,000+ active users weekly.

Outside of engineering, I mentor junior developers, contribute to open-source, and share my learnings through articles and tech talks.

Currently focused on DX with React 18+, internal tooling, and scaling UI systems across teams with clean code and modern frameworks.

Technical Knowledge Hub

Insights, tutorials, and experiences from my journey in software development. Sharing knowledge one post at a time.

cluster module in node js

The Cluster module in Node.js allows developers to create child processes, known as workers, that share the same server port. Each worker can handle incoming requests independently, taking advantage of multiple CPU cores. This distribution of tasks across workers ensures that the application can handle a larger number of concurrent requests, enhancing its performance and responsiveness.

Top 10 Common ReactJS Mistakes

Top 10 Common ReactJS Mistakes Every Web Developer Should Avoid

Typescript first Zod validation

Zod is a TypeScript-first schema declaration and validation library. It allows you to define schemas for your data and validate them against those schemas.

React Redux Toolkit

Redux Toolkit is the official, opinionated, batteries-included toolset for efficient Redux development. It provides utilities to simplify common Redux use cases, such as store setup, reducer creation, and asynchronous logic handling.

Next.Js authentication using Lucia

Handling authentication is a complicated yet crucial task. Recognizing the importance of a robust and secure authentication system, Lucia be an excellent solution for your next project. As a lightweight auth library specifically designed for TypeScript, Lucia abstracts the intricacies of managing users and sessions, making the developer’s job significantly easier.

Caching in React

Caching is a technique used to store data in a temporary memory area for faster access. In React applications, caching can significantly improve performance by reducing the time required to recompute values that do not change frequently. Two essential hooks for implementing caching in React are useMemo and useCallback.
