What I'm looking for

I seek remote roles building cloud-native, scalable backend systems and identity or AI-enabled products where I can own architecture, drive performance gains, mentor engineers, and deliver measurable reliability and cost improvements.

I am a software engineer focused on building secure, scalable backend systems and developer tools, with experience delivering production features across cloud-native environments. I have led schema and endpoint design, implemented consistent hashing and notification systems, and shipped daily product improvements for remote teams.

I have driven performance and reliability gains — reducing memory-related downtime by 65%, improving search load times by 45%, and cutting page loads by 40% — while contributing to SSI identity tooling, DIDComm integrations, export systems, SDKs, and robust testing practices. I enjoy mentoring engineers, owning architecture, and solving distributed-systems and cloud challenges.
