About Ed
I’m Ed Henderson. I am SharperTool. Electrical engineer and software developer in Boise, Idaho. Hands-on in the code most days.
Path
Navy electronics first. Then semiconductor test hardware — imaging and test systems in the Micron-era orbit — where hardware and software had to agree or nothing shipped. After that, full-stack and cloud. Same person: make the system reliable, keep the feedback loop short.
I grabbed sharpertool.com the day the name became available. The public site sat too long as a leftover sales page. This version is about the work.
How I work
I run engineering and I still write the code. Architecture, delivery, growing engineers. Calm systems over heroics. Prefer clear ownership and small diffs that land.
At Landlord Tech I’m the hands-on Senior Engineering Manager with a distributed team across the US and the Philippines. Core product is Java/Spring Boot, PostgreSQL, and React/TypeScript. The Health Professionals app is Django 5, PostgreSQL, and OpenSearch. Remote is normal. Time zones are a design constraint, not an excuse.
AI tooling
Claude Code lives in the repo — same place the engineers do. My workflow is AI-first: I design the system, set the architecture and intent, and direct agents through the build. For review, AI gives me an overview of each PR — what it does, the key parts, where the risk is — and I go deep on the parts that matter and add what I know. I stood up an AI builder that can take a task through to a pull request, and harnesses that let agents run, test, and fix their own work. Projects →
Grok Bot handles the orbit around the work: notes, drafts, the scaffolding so I can stay on the actual problem. Tools, not a slide deck.
