Backend & Cloud Engineer · Python · AWS Serverless · Event-Driven Architecture
Building production-grade distributed systems and the developer platforms that make them easier to work with.
A production-grade, event-driven order processing platform on AWS serverless — and a developer platform layered on top of it.
- Event schema layer — 9 Pydantic v2 event models, field validators, StrEnum constraints, correlation ID threading for distributed tracing
- Service layer — OrderService, InventoryService, PaymentService, NotificationService wired through an in-memory event bus (in progress)
- AWS infrastructure — EventBridge, SQS, Lambda, DynamoDB via AWS CDK (TypeScript) (coming Sprint 3)
- Developer platform — CLI scaffolding tools and CDK L3 constructs (coming Phase 3)

Five years of backend and cloud engineering across AWS, Bloomberg Industry Group, and Cognizant. Partner Solutions Architect at AWS. Before that, 15 years in education — which is why I can explain a distributed system on a whiteboard in a way that actually lands.
Currently building EventFlow as a portfolio project while preparing for a full-time backend/cloud engineering role (available summer 2026).
