Full stack developer building clean, functional and agentic AI products.

I'm Sandeep Singh - a full stack developer.

I design and ship end-to-end web and mobile applications, from the database to the pixel. I care about fast load times, clean interfaces, and code that's easy to live with.

About

I care about the code that matters and the user experience.

I've spent the last several months building products end to end — shaping the data model, wiring up the API, and obsessing over the last few pixels of the interface. I like working close to the whole stack because that's where the interesting trade-offs live.

Outside of my professional work I build small tools , projects to learn new technologies , Agentic AI to develop smart applications, write about what I learn, and keep a soft spot for fast, quiet software that respects the people using it.

Available for select projects

I am starting to take on select freelance projects. A few things I help with:

  • Web Application Development
  • Mobile App Development (React Native)
  • REST API & Backend Systems
  • Full-Stack Product Development

My process

  1. 01 Discovery — I scope the problem, the users, and what end product looks like.
  2. 02 Plan — I map the architecture, milestones, and a realistic timeline.
  3. 03 Build — I ship in tight iterations with regular previews you can try.
  4. 04 Launch & support — deployment, handover, and help once you're live.

Server-Sent Events (SSE)

A practical, hands-on tour of real-time on the web — what 'real time' actually means, how SSE is just a long-lived HTTP connection, how it differs from WebSockets, and how to build one end-to-end with Express and a plain HTML page.
