Siri Hansen is an experienced Erlang developer with over 25 years working with Erlang/OTP, including long tenure on the Ericsson Erlang/OTP team and later roles in banking and fintech. She combines deep systems-level expertise—kernel, sasl, disk_log and logger—with practical experience improving build and test infrastructure for widely used projects like rebar3. At Nordnet and Sharpfin she applies telecom-grade reliability practices to financial systems, bridging legacy runtime internals and modern CI-driven development. Her academic background in signal processing and electronics informs a methodical approach to low-level debugging and performance-sensitive code. Colleagues rely on her for tough edge-case fixes and for strengthening test coverage around compiler and filesystem behaviors. Based in Stockholm, she brings a steady, hands-on engineering presence to complex distributed and embedded systems.
