How we work
Most of our clients are in a different country from us, so we've learned to work the way you already do: your repositories, your tracker, your chat, and a daily overlap in hours agreed before the first sprint. You get a short written update every week, a demo every sprint, and a founder on the call when it matters.
Web platforms, APIs, mobile apps and the integrations between them, on Java, .NET, Node and React, with Kafka for events and Keycloak or Entra ID for sign-in. Built to your standards, reviewed before it ships.
Cloud and DevOps on AWS, Azure or Google Cloud, with Kubernetes, Terraform and pipelines your team can read. QA wired into CI. Support and upgrades for the software you can't let age.
Security is part of every project, not a separate quote. Identity and access, hardening, and the tools you already run, from Palo Alto and Fortinet to CrowdStrike, Intune and Okta.
We don't start with a model, we start with one workflow that costs your people time: answering from your documents, reading invoices and contracts, handling tickets and email. Then we build an assistant or agent for that one job, on OpenAI, Claude or Azure OpenAI, or on a local model if your data can't leave the building.
Every agent we ship answers with sources, works only with the access its user has, and asks a person before doing anything that's hard to undo. We measure it against real cases before it goes live, and keep measuring after.
Your ERP, CRM, core banking and internal tools don't get rewritten. We connect through APIs, queues or the database, in Salesforce, SAP, Dynamics or ServiceNow, and the same team that built it keeps it monitored and maintained.
Engagement
Switch models as your project changes. No lock-in beyond notice periods.
A stable team that works only for you, managed by your product owner.
Fits when you run a long-lived product and want capacity that stays.
A defined deliverable with a fixed price and milestones.
Fits when you need an MVP or a migration delivered without running the project yourself.
One or two specialists added to the team you already have.
Fits when you have a team and a process and are missing a skill or need extra hands for a peak.
Process
Each step has a clear exit if it is not a fit.
We learn your product, stack and the roles you need.
You review engineers and interview the ones you like.
The team starts on a real task, with no long-term commitment yet.
Weekly demos, shared dashboards and a named delivery manager.
