I build the boring, unglamorous systems companies actually run on.

My work sits at the seam between product and infrastructure: fund administration software handling millions in distributions, CRM and ERP rollouts for regulated teams, and an evolving cast of agentic systems that do the work nobody at a fifty-person startup has time to do themselves.

I am the co-founder and CPO of Homebase, a Techstars ’23 proptech building fund management for real-estate sponsors. Outside of Homebase I take on a small number of consulting engagements under AKBUILDS. Usually 1 to 2 at a time, usually agents in production, always with real deliverables that hold up and continue to improve long after I move on.

I write code in TypeScript and Python and ship on AWS, Cloudflare, Vercel, and Fly.io. I prefer flowcharts to powerpoints and short meetings to long ones. I am always curious and love working with great people.

What I take on
  • Agentic systems with real production guardrails
  • Full-stack platforms in regulated industries
  • ERP / CRM rollouts and change management
  • Product engineer or fractional-CAO work
Not the right fit
  • Pure design-only engagements
  • Static marketing brochure sites
  • Hourly maintenance retainers
  • Siloed engineering engagements

I build systems that
are self-improving
and resilient.

Most of my work now runs as supervised agents - I research best practices, plan it, dispatch it across parallel sessions, and gate anything that touches production. The point isn't speed; it's that the result is stable, repeatable, and still working long after I move on.

i

Research, plan, build, test, deploy, verify - in one pass.

A feature goes from an idea to a spec to a deployed, health-checked endpoint in a single engagement, not a half-finished draft thrown over a wall. Shipped means it runs in production and stays up.

ii

Agents in parallel, with a human at the gate.

I fan out Claude agents across git worktrees and codebases - one spec becomes dependency-ordered issues, parallel implementations, and reviewed PRs. The orchestration is autonomous; the approval gates on anything irreversible are not.

iii

Verify against reality, not the compiler.

End-to-end checks over static ones, because passing types don't mean a thing works. This is how I have caught canonical-URL regressions, duplicate-send bugs, and a dead-weight timestamp change - each invisible to the compiler, each found by exercising the real system. The result holds up on the hundredth run, not just the first.

agents supervised, not trusted

Selected work.
Six deep, nine short.

The first six are flagship engagements I can speak to at length. Tap any of them for the full case study. The others are smaller but still mine end-to-end.

What I'm
actually doing
right now.

A small public log. Updated by hand, not by a script. If something here looks like a fit for what you're building, that's a good moment to reach out.

SidenoteThe "Now" page is a Derek Sivers idea. He calls it a way to make a website feel like it was written by a person rather than a press release. I agree.

This month
  • Building a custom agent for a Series B digital health startup so their team can run ERP operations (records, SuiteQL, inventory status, lot tracing) autonomously instead of clicking through screens.
  • Standing up SEO and AIO (AI-answer optimization) improvement loops for the Homebase marketing site: measure what search engines and LLMs surface, fix the gaps, repeat.

Two ways to
work together.

Hire AKBUILDS for a focused engagement, or bring me in-house. Either way, the work is production software with a real deliverable, not a deck.

Hire AKBUILDS

What I build

  • Production AI agents with real guardrails, evals, and human-in-the-loop
  • Full-stack platforms for startups and regulated industries
  • ERP / CRM integration and automation (NetSuite, HubSpot, Salesforce, Attio)
  • Custom MCP servers and internal tooling that compounds

How I work

  1. 01
    DiscoveryA short paid sprint to map the problem, the systems, and the riskiest assumptions before anyone commits to a build.
  2. 02
    Build in productionI ship into your real stack in tight increments, with tests and evals from day one, so you see working software early and often.
  3. 03
    Clean handoffDocumentation written for your team, not for me. The goal is a system you can run and extend without me in the loop.
Or bring me in-house

What I'm looking for

Roles
Chief Product Officer, Chief Agent Officer, product engineer, or forward deployed engineer
Stage
Series A to Growth, AI-native or regulated-industry teams
Where
New York, NY or remote
What gets me in
Hard production problems where AI is core to everything + the opportunity to work with great people
