01About

Product-minded engineering, not just pixels.

Portrait of Nirmal Kumar G sitting at a seaside café

I’ve spent my career on high-traffic web apps, SaaS products and enterprise platforms, working closely with product owners, designers and backend teams.

My focus is code a team can live with: clear frontend architecture, predictable state, sensible APIs and pages that stay fast as features pile up. A quicker checkout or a cleaner dashboard is what actually moves the numbers, so I care about the business side too.

Alongside hands-on development, I lead and mentor engineers, review code and help teams make architecture calls they won’t regret six months later.

05Approach

How I build.

Working principles, each one tied to something I’ve actually done.

  1. 01

    Components a team can reuse

    Shared building blocks beat one-off screens. Typed props and modular styling keep them predictable to change.

    Reusable UI shared across the Trade Brains products; typed components at Videonetics.

  2. 02

    Render what search needs on the server

    Pages that depend on organic traffic are server-rendered, so content is in the HTML before any script runs.

    FinGrad course pages built on Next.js.

  3. 03

    Measure performance, then fix it

    Profile first with Lighthouse, DevTools and WebPageTest, so effort goes where the time is actually lost.

    Load time improved by 30% on Videonetics interfaces.

  4. 04

    Tests around the flows that matter

    Critical user journeys get unit tests, so a refactor or a defect fix doesn't quietly break them.

    Jest and React Testing Library on enterprise banking workflows.

  5. 05

    Clean seams with the backend

    Interfaces integrate with REST services through clear contracts, and I can work on both sides when needed.

    REST integrations across products; Node.js, Express and MongoDB experience.

  6. 06

    Leadership through review

    Code reviews, mentoring and written technical decisions that a team can revisit months later.

    Technical lead at HCLTech.
