Shipped for enterprise & startup teams
[ What I do ]
An AI automation consultant and AI agent developer who also owns the product and the cloud it runs on — agents where they earn their keep, product where it matters.
As an AI automation consultant, I build agents that answer from your own data with citations, triage inboxes, and run the workflows your team repeats every week — wired into your systems through MCP, with guardrails and evaluation built in.
Includes
Web products built end to end — Next.js front ends, TypeScript back ends, PostgreSQL — shipped in weekly increments you can see and use.
Includes
AWS serverless architecture proven on fintech, insurance, and streaming platforms — event-driven, observable, and designed for the compliance you actually face.

[ How we work ]
Every engagement starts with a free call and a written scope, so you can hire a senior AI engineer without a full-time hire. Work happens in your repos and your cloud, with a demo every week.
A written proposal with scope, timeline, and price. Most projects run 4–12 weeks with weekly demos.
A standing weekly allocation for teams that need senior AI and full-stack capacity without a full-time hire.
Embedded in your team, your repo, and your rituals — shipping alongside your engineers and mentoring as I go.
[ Testimonials ]
Consistently delivered quality outputs. Highly skilled technically, mentors his teammates, and runs the extra mile to beat tight timelines.
A rock-solid teammate. Karl's straight-shooting honesty makes collaboration easy and refreshing.
I truly love the work you've done, and everyone I show it to is equally impressed. I'm really looking forward to collaborating on other platforms.
Karl understood our needs from day one. He didn't just build us a website — he built a platform that serves our community.
No. Ministry is a focus, not a boundary. Most of my engineering years were spent on enterprise fintech, insurance, and SaaS platforms, and I take on startups and businesses whose work I can stand behind.
Small automations and integrations typically start in the low four figures; custom agents and full products range from $10k to $50k+ depending on scope. Fractional and retainer arrangements are priced per week. Every engagement starts with a free call and a fixed written proposal.
Async by default, with a weekly demo of working software. Work happens in your repositories and your cloud accounts, so there is nothing to migrate when we finish.
You do. Code lives in your repos from day one, and I choose AI providers and configurations with appropriate data agreements — and document exactly what goes where.
Yes. I have shipped as an embedded engineer on enterprise teams and mentored as I went. If you have a team, I fit into its rituals rather than replacing them.
