Hello, we are Harpy Division

A compact team of engineers building reliable backends, web services and infrastructure — and then trying to break them ourselves. We ship Go, Python, JavaScript and Elixir, deploy to Kubernetes and bake security in from the very first commit.

// SKILLS

Our Core Skills

Hands-on practice, not theory: we build fast APIs and realtime services, find vulnerabilities before attackers do and watch threats in real time. For analysis and monitoring we rely on Wireshark, Burp Suite, Metasploit and Splunk.
