Who I am

I care about the half-second between someone speaking and the screen answering.

I am a frontend engineer at SparkTG, on a cloud communication platform — cloud telephony, IVR and AI voice bots. My work sits where a person and a system meet: an embeddable WebRTC calling widget in production at Zomato Nugget and Eternal, and SparkChat, an AI chat widget embedded on more than 100 client websites.

Before that I built a fashion e-commerce platform end to end, and enterprise FinTech dashboards at Wipro with Java Spring Boot behind them. Four years, one through-line: interfaces that have to stay correct while data is moving underneath them.

What that means day to day

  • WebRTC media that survives a dropped connection
  • Optimistic UI over WebSockets, reconciled without flicker
  • Web Components that stay isolated inside someone else's page
  • Accessibility verified, not assumed — WCAG AA
  • Bundles split, measured, and kept under budget

How I work

Four rules I actually follow.

  1. 01

    Latency is a feature

    The half-second between someone speaking and the screen answering is the product. I measure it, budget it, and defend it — reconnects, optimistic updates and skeletons are all in service of it.

  2. 02

    Accessible or unfinished

    WCAG AA is the floor, not the ceiling. Focus rings, labels, and a layout that holds from 320 to 2560px are part of done, because the interface is where people talk.

  3. 03

    Ship, then sharpen

    Production beats perfect. Get it correct and observable first, then take the second pass on polish — never the other way round. Nothing ships without tests and a way to see it fail.

  4. 04

    Own the whole path

    From the component to the CI to the incident channel. I would rather understand the entire route a request takes than hand off the parts I find uncomfortable.

The path

4+ years, three companies, one direction.
