Engagements
Hire me for the layer nobody else wants to own
I've been independent since 2011 — fifty-plus shipped projects for startups through Fortune 500s, usually brought in for the problem the in-house team couldn't crack. Two engagement shapes cover most of what clients need from me now.
SDK build & rescue
surfaceFor platform companies whose native SDKs are missing, thin, or hurting integrations. I design and ship Swift, Kotlin, JavaScript, and WebAssembly surfaces over Rust and C++ cores — API design under semver, FFI correctness, binary size, ABI stability, and documentation your integrators actually read. Recent proof: three years as sole owner of a commercial iOS SDK over a 256KLOC C++ engine, and top-5 contribution to wasm-bindgen, the binding generator itself.
AI systems that hold up
coreAgent tooling, evaluation harnesses, and LLM integrations engineered like systems software: cost governance, streaming robustness, failure taxonomies, reproducible evals. Also: hardening the "almost right" code AI wrote for you — most developers now report debugging AI output takes longer than writing; I make that problem go away before it reaches customers. Proof: 104 model configurations in production at botmafia.games, and a published agent-tooling suite.
Start here
Start with a one-week assessment.
AI-Code Reliability Assessment
$10,000one week
A focused review of AI-written or AI-dependent production code: failure modes, eval coverage, streaming behavior, cost controls, and operational risk. You get written findings and a prioritized hardening roadmap.
SDK Integration Assessment
$10,000one week
An API, ABI, FFI, packaging, documentation, and integration audit for a missing or struggling SDK. You get written findings and a prioritized build-or-rescue roadmap.
Other ways to work together
Advisory retainer
$3,500per month
Asynchronous advice plus two calls each month. This is guidance and review, not code delivery or an on-call arrangement.
Office hour
$75060 minutes
One focused 60-minute working session for a gnarly SDK, Rust, WebAssembly, FFI, or AI-systems problem.
How it works
Assessment first, then fixed scope
1 — Assessment. I spend one week in your codebase and deliver written findings and a prioritized roadmap. You can hand that report to anyone — including someone cheaper than me — and it will still be worth it. The assessment is a defined investigation, not a promise to implement every recommendation.
2 — Fixed-scope build. The plan becomes a scoped engagement with a deliverable: an SDK, a subsystem, a hardened pipeline. Build engagements start at $10,000/week; follow-on work is scoped separately.
3 — Handoff that sticks. Documentation, tests, and CI are part of the deliverable, not an extra. I embed with your team during integration; the goal is that you don't need me afterward.
Code-delivery build engagements include a 30-day warranty for material defects attributable to my delivered work. It is not an SLA or on-call promise, and it does not cover new requirements, client modifications, or third-party platform changes.
A few honest constraints: I'm in Austin and work remote; I take one substantial engagement at a time; and if your problem is better solved by a framework, a hire, or nothing, I'll say so at the assessment stage. I'm also open to the right full-time staff/principal role in SDK or AI-infrastructure work.
Start with one paragraph.
What you're building, where it hurts, and what you've tried. I reply to every serious inquiry — usually with a question you haven't been asked yet.
