Independent technical product engineer

You have a technical or product problem that isn't fully defined yet.

I help you figure out what it actually is — and what to do about it.

Bring me in when…

  1. The problem isn't fully defined yet

    You know something is wrong or something needs to be built, but you're not sure what exactly. I help you figure that out before making decisions.

  2. You need a second opinion on a technical direction

    Architecture, stack decisions, infrastructure choices — you want someone who can evaluate the tradeoffs with both technical depth and product context.

  3. AI-generated code needs a real review

    You shipped fast with AI assistance. Now you need a human to assess what actually holds and what doesn't.

  4. You're stuck between options

    The path forward isn't obvious and you need an experienced perspective to break the deadlock.

  5. The answer might involve building something

    If the problem calls for a prototype or implementation, I can do that too — not just advise.

Focus areas

  • systems

    Software Architecture & Product Engineering

    From first prototype to production systems: pragmatic structure that supports the product, not the other way around.

  • infrastructure

    Infrastructure & DevOps

    Self-hosted systems, CI/CD pipelines, cloud infrastructure, and Linux environments that are reliable and maintainable.

  • prototyping

    Technical Prototyping

    When the answer to a problem is a working thing, I can build it — from quick proof-of-concept to functional MVP.

  • custody

    Bitcoin & Self-Custody

    Hardware wallets, key management, and custody setups that match your actual threat model.
