Backend engineer · identity for humans & AI agents · safe agent runtimes

I build the backend systems people trust with their identity — and, increasingly, the identity of the AI agents acting on their behalf. Ten years of designing, scaling, and quietly keeping alive the infrastructure underneath identity, verification, and safe agent execution.

what_i_do

// identity_systems

Digital identity, for humans and agents

Verifiable credentials and open standards like OID4VP/OID4VCI — and the delegation model AI agents need to act on someone’s behalf without becoming the new attack surface.

// backend_architecture

Systems that stay boring

Designing, modernizing, and scaling cloud-native services on AWS — including the sandboxed runtimes that let AI agents execute safely, not just quickly.

// technical_leadership

Teams that ship with confidence

Leading system design across product, infra and security teams — and mentoring engineers to own architecture, not just tickets.

open_source

// dart_package

aws_xray_sdk — AWS X-Ray distributed tracing for Dart

Auto-traces dart:io HTTP and Smithy SDK clients, propagates X-Amzn-Trace-Id, and sends segments via UDP. First-class Lambda support. Verified publisher on pub.dev.
