I lead architecture across a few product lines and work with the teams that have to live with the calls. A large part of the current work is moving systems from AWS onto on-prem.

• AWS to on-prem migration, and Kubernetes as the runtime we adopted for that estate
• Leading AI adoption: showcases, and teaching teams agentic development with Claude Code and Cursor
• Step-up authentication for APIs and apps: an existing session can raise its access level after a second factor, instead of treating 2FA as a login-only gate
• Paid subscriptions we sell: the path that creates a plan, changes it, and decides what the caller is allowed to do
• Fraud prevention in Snowflake: features for scoring, which of those features actually moved the metric, backtests, and alerts. Snowflake Anomaly Detection on unusual patterns

Cross-team architecture across 6 scrum teams. This is where the remittance rewrite landed: the monolith came apart and the new services took the load.

• Led architecture of the remittance platform through more than 100× growth in monthly transaction volume, completing its multi-year decomposition from a monolith into services
• Helped teams design pricing, transaction processing, and notifications so the money path stayed correct across services
• Re-architected core financial services from Oracle onto MongoDB
• OIDC with AWS Cognito and Google federation
• Migrated enterprise services from AWS SNS/SQS to Kafka
• Financial Transaction Audit Trail for SOX
• Observability with Grafana, Prometheus, and OpenTelemetry

Started the remittance rewrite: decompose the monolith, give teams their own services, and stop treating infrastructure as a ticket to SysOps.

• IaC via AWS CDK so scrum teams owned infrastructure changes. 5x increase in change frequency, no more centralized SysOps bottleneck
• Decomposition roadmap for the remittance monolith, and the first services off it
• Replaced synchronous API calls with Kafka
• Pricing and Loyalty services with domain-driven design
