Building telecom infrastructure, queue systems, and production backend tools.

I build practical backend systems, VoIP/telecom infrastructure, real-time platforms, and internal tools that need to run reliably in production.

My strongest areas are SIP/VoIP systems, high-concurrency services, queue and worker architectures, Linux operations, and full-stack product delivery when the backend needs to be tightly connected to the user workflow.

Currently focused on:

• VoIP monitoring, SIP infrastructure, and telecom testing workflows
• Queue systems, retries, background workers, and storage abstraction design
• Production backend platforms with clear deployment and operational paths
• Open-source contributions in telecom, observability, identity, and developer tooling

I contribute to open-source projects where I can improve backend behavior, developer experience, protocol tooling, or system reliability.

• SIPp: configurable Call-ID generation, startup workflow improvements, and SIP traffic generation usability.
• Keycloak: account console locale handling via kc_locale.
• Grafana: DataSourcePicker correctness around filtered current data sources.
• Prometheus: proposal and implementation work for preserving PromQL parser comments.
• Asynq: exploring a lightweight pluggable backend/storage abstraction while keeping core dependencies small.

• tools: add DTLS-SRTP diagnostic handshake probe — merged
• tools: add ICE connectivity, STUN and TURN probes — open
• tools: add RTCP/SRTCP QoS analysis and MOS estimation — open
• tools: add RTP/RTCP media impairment proxy — open
• tools: add CI-native threshold reports and machine-readable results — merged

• sync master into X-Call-ID filter branch — merged
• sync master into tls statistics branch — merged
• sync master into json boolean branch — merged
• tools: add DTLS-SRTP diagnostic handshake probe — merged
• tools: add ICE connectivity, STUN and TURN probes — open
