mordcole/README.md

Hi there πŸ‘‹, I'm Mordecai!

I'm a full-stack software engineer with experience in the JavaScript, TypeScript, and Python ecosystems. Recently I've been applying that foundation to AI, building and shipping systems for running and observing agents.

πŸš€ Amber

Amber is an open-source, self-hosted runtime that adds durable execution and observability to AI agent workflows. It is built on DBOS and Postgres and targets developers using the OpenAI Agents SDK.

Technologies: Python, TypeScript, FastAPI, DBOS, OpenAI Agents SDK, React, Astro, Docker, Terraform, AWS (ECS Fargate, RDS, RDS Proxy, ALB, CloudFront, S3, ECR, VPC, IAM)

🧩 Other Projects

Infinite Context: a personal RAG application that ingests notes, commits, and transcripts into Pinecone and synthesizes answers with GPT-4o. It surfaces a coverage signal so you can tell when the retrieved context is thin rather than getting a confident answer built on nothing.

RequestBin: a real-time webhook inspection tool. It gives you a unique URL to point a webhook at, then captures and displays each incoming request so you can see exactly what a service is sending.
