Full-Stack SaaS Developer

I build software that helps businesses automate, scale, and grow.

From idea to production — SaaS products, internal tools, and AI-powered applications built with Next.js, React, Firebase, and Node.js. Not demos. Software businesses actually run on.

I don't build demos. A demo works on my laptop, in a clean tab, with no real users pushing on it. Software I ship has to survive the messy version of that: real data, real edge cases, someone's business depending on it at 2am.

That's the bar — not "does it work," but "does it still work in six months, under load, when nobody's watching."

How I Work

A predictable process, not a black box

You always know what's happening, what's next, and why.

01

Discovery

Understand the business problem, users, and constraints before touching architecture.

02

Planning

Design a system that fits the actual scale needed — not over-engineered, not fragile.

03

Development

Ship in reviewable increments with working software at every stage, not one big bang.

04

Testing

Verify against real edge cases, not just the happy path — before it's ever a client's problem.

05

Deployment

Ship to production with monitoring in place from day one, not bolted on after something breaks.

06

Support

Stay reachable after launch — software is a relationship, not a handoff.

Tech Expertise

Tools chosen for reliability, not resume-padding

A focused stack I use in production — not a list of every framework I've ever touched.

Client Voices

What clients say

We needed a site that made a sophisticated investor stop scrolling and take us seriously. What we got structured our whole thesis clearly and read as established from the first screen — no back-and-forth needed to get there.

Karan M. · Managing Partner, Private equity firm

Guests kept commenting on how easy the site was to browse before booking. The gallery-first layout does the selling for us — we barely have to explain the property on calls anymore.

Priya S. · General Manager, Boutique hotel group

Delivered exactly the credibility-first tone we were after. One round of feedback on copy took a bit longer than expected, but the end result was worth the wait.

Devendra P. · Founder, Family office

Having the website and the ordering app built by the same person meant nothing fell through the cracks between them. Customers now find us and order without bouncing between two disconnected experiences.

Meera N. · Owner, Restaurant brand

International buyers judge you in the first ten seconds on a site like this. Ours finally looks like a company worth doing business with, not a brochure from a decade ago.

Rajesh K. · Export Director, Trading & import-export company

Field staff who'd never file a digital report before picked this up without training. That's the actual test for tools like this, and it passed — reports come in consistently now instead of on paper at month-end.
