I automated my job search. Here's what actually works.
Six months of building a job application pipeline with Claude and AWS. The architecture, the failure modes, the current state of the system.
Read →When the pool runs dry: scoring functions and the empty-pipeline problem
My auto-apply pipeline hit a wall: 971 job listings marked new, zero qualifying applications. Here's what the scoring distribution revealed and what to do about it.
Read →Why TicketScope is a Chrome extension first, not a Marketplace app
The ConnectWise Manage app marketplace would take 6-8 weeks to review. A Chrome extension takes 60 seconds to install. Here's why I started with the extension.
Read →The SQS FIFO queue that lets a Lambda run 50 overnight jobs without timing out
Lambda has a 15-minute execution limit. An overnight job that processes 50 items needs hours. The coordinator/worker/SQS FIFO pattern solves this — each item gets its own Lambda invocation and full timeout.
Read →The one wrapper that makes LLM tool calls production-ready
An LLM agent that lets exceptions propagate from tool calls will silently stop working at 2 AM. One wrapper function prevents this — and it changes how you design every tool.
Read →The OSS dependency that was unmaintained for two years before we noticed

Read →The DynamoDB memory that survived 6 months of production
How to give a personal AI agent durable memory using DynamoDB — the four-table schema that handles conversations, facts, preferences, and tools without ever running a migration.
Read →The Slack notification that would have posted 200 times on day one
How I learned that notification products have two failure modes: the day-one flood and the ongoing noise. A ConnectWise-to-Slack bridge built around both.
Read →The cert that expired at midnight and nobody knew until 9 AM
A production TLS cert expired while everyone was asleep. Nine hours of quiet downtime before the on-call engineer caught it. This is why I built CertWatch.
Read →The AWS bill that tripled (and how I didn't notice for six days)
How an EC2 instance I forgot to terminate ran for six days before I noticed — and the tool I built to make sure it doesn't happen again.
Read →The AI chief of staff is a job title waiting to be invented
Founders pay $8k/month for a human EA who does scheduling and email triage. The same workflow runs on $25 of Claude API calls. Here's what's missing.
