Examples
Where this shows up
Public examples and pages that connect the skill to code, decisions, or delivery work.
Can lead and explain
There is enough structure, tradeoff reasoning, and explanation to evaluate leadership depth.
- Approval workflow API walkthrough
Covers the TypeScript path through workflow rules, REST-shaped boundaries, structured errors, and mapped tests.
- CDK construct library for durable serverless workflows
Shows TypeScript used for reusable AWS CDK construct design, generated infrastructure, and assertion tests.
- Operating an event-driven workflow under failure
TypeScript workflow engine logic and tests covering retry, DLQ, backlog signals, idempotency, and correlation continuity.
- Trunk-based delivery modernization
Covers the same delivery-gate policy implemented in TypeScript with vitest coverage.
Project implementation
There is working implementation behind the example, with source and tests.
- Redis/ElastiCache platform caching across serverless apps
Uses a public companion repository with deterministic TypeScript modules and tests to model the platform pattern without employer code.
Professional context
Where I have used it
My current backend and cloud work uses TypeScript and Node.js for AWS serverless services, integrations, and infrastructure tooling. I use it where typed boundaries and fast tests help keep cloud pieces understandable.
