I build the apps your business runs on.

I’m Dheeraj, a full stack developer. I build web apps, mobile apps and desktop apps for businesses, from the first idea to launch day and long after.

From front-end to full stack to building on my own.

I started as a front-end developer, obsessed with how screens look, feel and respond. Then I wanted to know what happens after someone taps the button, so I grew into a full stack developer: APIs, servers and databases, with six years building and supporting live apps.

Keeping those apps running in production taught me the most: software only matters when it works for the person using it. In December 2025 I went freelance, so I could build directly for the businesses and people who use what I make.

Pinned above my desk · what I care about
Works on a cheap phone and a slow connection.
Your staff get it on day one.
You see progress every week.
You own the code and the data.
Built so it can grow with you.
When it breaks, I pick up.

What I can build for you.

Most projects start with the same sentence: “we do this by hand, and it’s slowing us down.” Here’s what I can turn that into.

01Business websitesFast, mobile-friendly sites that turn visitors into calls and enquiries.
02Booking & appointmentsCustomers pick a slot and get reminders; you see the whole day at a glance.
03Customer portalsSecure logins where customers see their own orders, records and invoices.
04Dashboards & internal toolsReplace messy spreadsheets with one tool, with the right access for each role.
05Mobile companion appsPut your service in your customers’ pockets on iPhone and Android.
06Upgrades & integrationsModernize an old app, speed up slow pages, or connect payment, video and messaging services.
07SaaS platformsSubscription software with sign-ups, plans, billing and a dashboard for every customer account.
08E-commerce storesProduct catalog, cart, secure payments and an order dashboard you run yourself.
09Real-time appsLive chat, notifications and tracking that update instantly, powered by Node.js.

How I build it: idea to launch in five steps.

Each step ends with something you can see and react to, so the app you get is the one you actually wanted.

  1. 01 · ideaListenA call about your business, your users and what success looks like.you get → a one-page scope
  2. 02 · sketchSketchWireframes of the key screens, plus how your data will be organized.you get → wireframes to review
  3. 03 · prototypeBuildA working version early, growing in small pieces with demos along the way.you get → a live preview link
  4. 04 · shipLaunchTested on real phones and browsers, deployed, and handed over properly.you get → your app, live
  5. 05 · iterateImproveFixes, new features and speed-ups as your business grows.you get → ongoing support ↓

After launch, I stay.

I spent years supporting live apps, so I know the real work starts once people use them. I keep your app healthy, fix what comes up quickly, and keep improving it as you learn what your customers need.

Example · when something breaks
“The contact form isn’t sending on some phones”
reportedYou send me one message. That’s all.
reproducedI find the exact phone and browser where it fails.
fixedPatched, tested, and deployed without taking the site down.
verifiedI confirm with you, and check that no enquiries were lost.

Web, mobile and desktop. One builder.

Whether your customers reach you in a browser, on their phone, or your team works at a desk all day, I build the app and the system behind it, so everything shares the same data and stays in sync.
