Agentic systems
AI agents that act, not just answer
Agent pipelines that plan, decide and act across your tools, data and APIs. Built to be observable and safe to run in production, not just a demo.
Bluedev.in · Software & application development studio
We build the software behind the idea.
A small freelance studio designing and shipping agentic systems, web applications, mobile apps and custom software. We also maintain open-source packages developers already depend on.
Available for new projects
What we build
Four kinds of software, one small team.
We work as an extension of your team, from the first sketch on a whiteboard to what ends up running in production.
Web applications
Fast, accessible, built to last
Marketing sites, dashboards and full product builds, performant by default, easy to maintain, and never locked to a single vendor.
Mobile apps
Native-feeling, cross-platform
iOS and Android apps, most often shipped from a single Flutter codebase, built by the same team that maintains the packages that codebase relies on.
Custom software
Built around how your team works
Internal tools, integrations and systems shaped by your actual workflow, not a template. The source code is yours to keep.

Custom software, in the field.
One example of what "custom software" means in practice: a real system running at a real gate, not a demo.
Windows desktop · Computer vision
Parking ANPR
A desktop app for a gated parking area. It watches a camera feed, reads every plate that passes, and logs it with the time and a photo, automatically.
How a project runs
Four steps, start to finish.
There are no account managers and no lengthy sign-off chains. You talk directly to the people writing the code.
01 / Discover
Scope the real problem
A short call to understand the problem, the constraints, and what success actually looks like. From that we write a scope before any code gets written.
02 / Build
Iterate in the open
Focused, regular check-ins. You see working software early and often, not just a status report at the end of a sprint.
03 / Ship
Get it into production
We handle deployment ourselves, from app store submissions to production infrastructure, so launch day isn't a separate project.
04 / Support
Stay around after launch
Fixes, iteration and maintenance afterwards, on retainer or as-needed. The same team that built it sticks around to support it.
Open source
We publish what we build.
Alongside client work, we maintain open-source packages for the Flutter and Node.js ecosystems, published as bluedev.in on pub.dev and bluedev-in on GitHub.
From the blog
Notes on what we build.
Engineering write-ups, organised into categories, subcategories and subsubcategories as the list grows.
Open Source
Keeping Client Software Safe to Sell as Closed-Source
Before anything ships, we check that every component it's built on is actually allowed to sit inside closed-source software.

Building a Theme System for Flutter: Notes from cus_theme
A theme should feel like a normal part of the app, not extra ceremony.

Designing Tool Interfaces for Agents: What We've Learned
Most agent failures trace back to how a tool was described, not to the model behind it.
