DEVARUN Digital products, built end to end.

Digital products, built end to end.

We build full-stack web and mobile products, end to end.

We're a small team that takes products from first sketch to a live release — web apps, real-time features and Android apps, designed, built, deployed and handed over properly.

Services

What we build

  • Full-Stack Web Development

    We build complete web applications: React and Vite frontends, Node.js or Python Flask backends, and PostgreSQL databases — structured cleanly so they're easy to maintain and extend.

    • React
    • Vite
    • Node.js
    • Flask
    • PostgreSQL

  • Real-Time Application Features

    We add live features with WebSockets and Socket.io — chat, live location tracking, and dashboards that update the moment your data changes.

    • WebSockets
    • Socket.io
    • Live location
    • Chat

  • Android App Development

    We turn existing web apps into hybrid Android apps with Capacitor, and take them all the way through to a Google Play release.

    • Capacitor
    • Android
    • Google Play

  • E-Commerce Development

    We build custom online stores and customize Shopify themes, with payment gateway integration through Stripe or Razorpay — from catalogue and cart to checkout.

    • Custom stores
    • Shopify themes
    • Stripe
    • Razorpay

  • AI Chatbot & LLM Integration

    We build chatbot and LLM-powered features into products — like the AI assistant in AlgoViz, built on the Google Gemini API.

Case study

Life Link: finding blood donors, fast.

A real-time, GPS-powered Android app that connects blood donors with people who urgently need them — designed and built end to end by our team.

  1. The problem

    When someone urgently needs blood, time matters — and the hardest part is finding donors who are available and close enough to help, quickly.

  2. The solution

    Real-time GPS matching. Life Link uses live location to connect people who need blood with nearby donors, with updates pushed over Socket.io so matches stay current instead of going stale.

  3. The outcome

    A working Android app, built end to end — frontend, backend, database, real-time layer and Android build — and shipped to Google Play, where it is currently in testing.

In testing on Google Play

  • React
  • Vite
  • Node.js
  • Express
  • PostgreSQL
  • Socket.io
  • Capacitor

Case study

Orbit — child safety without 24/7 tracking

A privacy-first child safety app: parents set a safe radius, and the app stays silent until a child steps outside it.

  1. The problem

    In crowded places like fairs, malls, temples and train stations, parents lose sight of their kids for just a few seconds and have no way to know immediately. Constant GPS tracking solves this but feels invasive and drains trust between parent and child.

  2. The solution

    Orbit lets a parent set a “safe radius” around their child. The app stays completely silent while the child is inside it, and sends an instant alert the moment they step outside it — privacy-first by design, not always-on surveillance. A panic button lets the child share live location temporarily if they need to, and that location data auto-expires and deletes itself afterward.

  3. The outcome

    A working prototype with real GPS tracking, real-time alerts, the auto-expiring panic button, and a separate parent/child registration flow across two phones — currently being hardened for a Google Play release.

In development

  • React
  • Vite
  • Leaflet.js
  • Socket.io

Case study

AlgoViz — algorithms you can actually watch run

Interactive, step-by-step visualizations of sorting, searching and graph algorithms, with a built-in AI chatbot that explains each step.

  1. The problem

    Algorithms are usually taught as static pseudocode or a wall of text, which makes it hard to build real intuition for how sorting, searching, and graph algorithms actually behave step by step.

  2. The solution

    AlgoViz turns algorithms into step-by-step interactive visualizations, with a built-in AI chatbot (powered by the Google Gemini API) that explains what's happening and why at each step — plus a quiz mode and leaderboard to test what you've learned.

  3. The outcome

    A fully live, deployed product covering sorting, searching and graph algorithms, with JWT-authenticated accounts and a working quiz/leaderboard system.

FAQ

Good questions, straight answers.

Don't see yours? Get in touch and we'll answer it directly.

How does pricing work?

We don't publish fixed prices, because every project is different. After an initial conversation about what you need, we put together a quote for your specific project, based on its scope.

Scope and milestones are agreed together, so you know exactly what the quote covers.

What's your typical timeline?

Timelines depend on scope. We'll give you a clear estimate after an initial call.

Work is split into milestones, so you can see real progress along the way.

Do you work with international clients?

Yes. We work remotely and collaborate with clients wherever they are, using written updates and scheduled calls that we plan around your time zone.

What's your process?

One team owns the whole journey, in four steps:

  1. Design. We turn your goals into flows, screens and a plan you can react to before any code is written.
  2. Build. Milestone-based development, with working builds you can try along the way.
  3. Deploy. We ship to production — web hosting, or Google Play for Android — and verify it works.
  4. Handoff. You receive the code, documentation and a walkthrough, ready to run and extend.

Throughout, you get regular updates in plain language and a single point of contact.
