Harshit
Gupta.

Senior software engineer
— apps, web, cloud DevOps

Six-plus years building scalable web and mobile products with React Native, React, Next.js, Node and Java Spring Boot on AWS. I lead engineering teams, architect products from scratch, put CI/CD under them and make slow systems fast.

Fintech, ed-tech, healthcare, sustainability and enterprise SaaS — delivered for clients in India, Australia, Japan, the UK and the United States.

What I'm hired to do

Full stack,
ops included.

Most engagements pull two or three lanes at once — a React Native release that also needs its pipeline rebuilt, or a Next.js front end with the Node services behind it.

Product front ends and the APIs under them — dynamic dashboards, charts, data-heavy tables.

How I work remotely

No timezone tax.

I've delivered remotely for teams in Georgia (US), Australia, Japan and the UK from an IST base — four hours with US East, a full day with EU and APAC.

Overlap, not silence
Standups, reviews and pairing inside your working day. Six years of it across US, UK, Australian and Japanese teams.
Written by default
Decisions land in the PR, the ticket or a short doc — so the team keeps moving while I am offline.
Your tools, your process
Slack, Jira, Linear, GitHub, whatever you run. I adopt the workflow instead of importing mine.
Handover is the deliverable
Pipelines, dashboards and runbooks documented, so nothing depends on me staying.
