Software Development McLean, VA 201–500 employees Founded 2006 Privately Held

Harmonia (operating as Revolutional) is a systems integrator built around cloud-native transformation, data science, and cybersecurity for large organizations. The tech stack reveals a mature Java + Oracle backend with modern polyglot layers (Python, Node.js, React/Angular, Kafka) — suggesting they're actively migrating legacy monoliths to cloud. Active hiring across data (4 roles), engineering (4), and security (1) with a skew toward lead and senior positions points to scaling delivery capacity on large transformation programs, not early-stage product development.
