Products
Web applications with accounts, permissions, and a workflow someone uses every day.
Custom software and AI
Custom software and AI development.
Web applications, APIs, distributed systems, data pipelines and cloud. LLM applications, agents, retrieval, automations, MCP servers and forecasting.
Software, close up
A desk, a data center, and the hardware under the software.
A screen someone can use
Custom software is an interface and the system behind it: a queue, an API, and the jobs that keep running after the screen is closed.
The work
Two lines of work, quoted per project. Scope and price are agreed in writing, in US dollars, before anything starts.
Web apps, APIs, distributed systems, data, cloud.

What gets built
Named plainly. Each line opens the page that describes it.
Software
- Web applicationsProduct interfaces and the application behind them.
- APIsContracts other software can call without guessing.
- Backend & distributed systemsServices, workers, and the coordination between them.
- Data engineering & pipelinesFrom an event to a number someone can trust.
- CloudAWS, GCP and Azure.
AI
- LLM applicationsA model doing a defined job inside a product.
- AI agentsA sequence of steps, with tools and limits set up front.
- RAG & knowledge assistantsAnswers from material you actually have.
- Automations & integrationsA repeated task, connected, and still stoppable.
- MCP serversOne system, exposed to AI clients on purpose.
- ML forecastingA model of a series you already measure.
Process
How an engagement goes. This is the working method, not a wall of reviews. The longer version is on the approach page.
- 01
You email us
Tell us what you need. We confirm scope and price in writing before any work starts.
- 02
You share what the work needs
Code, data, or the least access required. We don’t ask for your passwords.
- 03
We build, you review
Where AI tools are used, a person checks the work before you are asked to approve it.
- 04
You approve
Nothing is published or changed in your accounts without your approval.
Where this kind of system fits
Products, operations, and knowledge systems.
Operations
The software behind a repeated job: queues, workers, and a record of what already happened.
Knowledge
Assistants that answer from material you already have, with the source still visible.
