Engineering services

Reliable systems, from design to operation.

Backend and distributed systems, enterprise integration, cloud and AI engineering. Every engagement starts with a short call and a written scope.

  • 01

    Custom software development

    Backends, APIs and web applications built around your business processes.

    • Payment and banking integrations
    • Reports and management dashboards

    • Performance and scaling risks
    • Security review
    • 90-day improvement plan
  • 10

    Technical leadership and engineering consulting

    Interim technical leadership for your team and the engineering practices that last.

How an engagement starts

  1. 01

    Request

    A short note about the goal, context and timing.

  2. 02

    Intro call

    We clarify the problem, the scope and the success criteria.

  3. 03

    Written proposal

    Scope, stages, timeline and terms. A confidentiality agreement comes before any code access.

  4. 04

    Delivery

    Short iterations, regular demos and transparent status.

We are a new company and do not yet have a public client history. The founder's experience at previous employers is personal experience, not projects delivered by the company. Every engagement starts with a concrete scope whose terms and outcomes are agreed in writing.
