Software development and consulting
APIs, back ends, mobile apps, and AI workflows, from initial architecture to ongoing maintenance. To see our full-stack capabilities in action, look at Fontavio: we built and maintain the entire ecosystem from scratch, including the Flutter app for Android and iPhone, the Python back end, a PostGIS database with hundreds of thousands of entries, and a programmatic static site covering thousands of cities.

Full-stack development
We build new systems from scratch or join an existing project. We cover the whole chain, from the user interface to the database and the server, so one developer is responsible for the parts working together. On an existing project we first read the code, the database and how it is deployed, and make changes in the project’s own conventions.
Tools: PHP, Python (FastAPI), JavaScript and TypeScript, Dart and Flutter, PostgreSQL and PostGIS, MariaDB, Docker, Linux, and Cloudflare.
- APIs and third-party integrations
- database design and fixing slow queries
- automated CI/CD and deployment pipelines
- e-commerce features
- mobile apps in Flutter

AI agents and workflows
All our development work is done alongside AI agents: the agents write code and tests from detailed architectural plans, and every single change is reviewed by a human before it ships. Fontavio was built exactly this way. Without AI agents, building an app of this scale would have taken significantly more time, budget, and manpower.
We build the same efficiency into client projects:
- agent workflows that take over repetitive manual work
- connecting language models (LLMs) to your existing systems and proprietary data
- MCP servers that give AI assistants direct access to your own internal tools
- code review and testing of AI-generated code
- the strategic plans and structure needed to let your own team get more out of AI agents

Consulting
We audit existing codebases, databases, and server setups, providing you with a clear, written list of what to fix and in what order. We can also join your team as a senior developer for a set period.
04 / 06 · Partnering
An app idea and a technical partner
If you have an idea for an app or a web service and are looking for someone to build it, tell us about it. We can build it as straight client work, or, for the right project, join as a technical co-founder or partner, with the work and equity agreed upon together.

FAQ
What clients and AI agents usually ask.
Do you build mobile apps?
Yes. Fontavio is built in Flutter, giving you one codebase that runs natively on both Android and iPhone.
Can you build an AI agent or workflow on top of our systems?
Yes. We start by analyzing which tasks repeat and where the data lives, then build a workflow whose output is reliable and can be easily checked.
Can you review code or a system someone else built?
Absolutely. You get a prioritized, written list of what to fix and how to improve it.
Would you join a startup?
Possibly. Pitch us the idea and show us what has been done so far. If the chemistry and project are right, we can explore it together.
