Software, apps, embedded systems and AI agents, built by one small studio that owns the whole stack.
We take projects that sit between disciplines: a backend that talks to firmware, an app with a retrieval agent inside it, a device that needs its own console. Fixed scope, a demo every week, and a handover you can run without us.
Five practice areas, one studio.
Each area has its own craft, tooling and track record. Pick the one closest to your problem, or start a conversation if it spans more than one.
AI systems
Agents that retrieve, reason and act inside your product: RAG over your documents, tool calling, multi-agent orchestration, and the tracing that shows what happened and why.

Products we ship ourselves.
Three products we design, build and run. They are the proof of the process below: real users, real uptime, real support tickets. Each has its own page on bunroo.in.
PiDesk
Managed thin-client fleet for the enterprise LAN — one server, dozens of fully-customized endpoints, zero per-seat licensing.

FinRoo
A personal finance companion that turns everyday money activity into a clear, actionable picture — built India-first.
UltraBike
A service-to-resale record for every vehicle you own. Calm over colourful. Data, not decoration.
Client and workshop projects
-
Travel agency websites with online payments
Booking sites for two agencies, built on Django and React with Razorpay and CCAvenue checkout.
-
ArmtronicLabs smart-home switches
Custom PCBs with embedded C firmware, MQTT to Alexa, and a Flutter app that controls the switches over the LAN. On Google Play.
-
AWS migrations and CI/CD for startups
Moving workloads onto AWS for cost and performance, with Terraform for the infrastructure and Jenkins or GitHub Actions for delivery.
Small team, fixed scope, weekly demos.
- // 01
A call to understand the problem
Thirty minutes, free. We ask what you are building, what already exists, and what has to be true when we are done. If we are not the right fit, we say so and point you elsewhere.
- // 02
A fixed-scope proposal
Scope, milestones, price and dates in writing within a week. Change is normal; it goes through the same document, not through surprise invoices.
- // 03
Working software every week
A demo of what changed, on an environment you can open yourself. Hardware work ships as photos, measurements and bench videos until the boards arrive.
- // 04
Handover you can run without us
Source, infrastructure as code, deployment runbooks and a written architecture note. We stay available afterwards on a retainer or per incident, your choice.
The stack we reach for.
Not exhaustive: the tools we actually use in production, grouped by what they do. We learn into whatever your problem needs.

Got a problem that sits between disciplines?
Software that talks to hardware. Apps people keep using. AI that does a job instead of a demo. Tell us what you are building; the first call is free, and you leave with at least one idea you did not have before.
