What I do

Experience from critical, secure financial systems, now applied to data platforms, custom business applications and Odoo.

  • Data platform engineering

    Lakehouse design with medallion architecture, Spark pipelines, Delta Lake on S3-compatible storage, Airflow orchestration, Kubernetes/OpenShift, and Starburst/Trino for consumption. Testing, observability and clean data contracts.

  • Custom applications & software architecture

    Business applications built to your needs in Java (Spring), Python or C/C++. Architecture and design from scratch, security by design, automated unit, integration and end-to-end tests, maintainable code. Design reviews and technical advice.

  • Odoo integrations & tooling

    Python automation and integrations over the Odoo API, migration from legacy systems into Odoo, data-quality audit tools, and safe bulk updates: plan and validate before write.

About

Miguel Cruz

Real Bytes Consulting is the consultancy of Miguel Cruz. I started at SWIFT in 2001 as a web developer — back when that was still a rare profile — and have been building software for financial infrastructure ever since.

I work in C/C++, Java and Python on Unix/Linux, and I am comfortable as an individual contributor, team member or technical lead. I work in English, French and Portuguese, and I am based near Ghent.
