Start a Project

Let's build it
together.

AI systems, web apps, SaaS, and business automation. From shaping the idea through build and operation — start with an email.

  • You can get in touch before the spec is settled.
  • Contract engineering and team augmentation go through this same form.
  • I read everything myself and reply within 1 business day.

Development inquiries & estimates

Fields marked * are required. Budget and timeline are optional — leaving them empty is fine.

Not sure what you want built yet? SUMI Smart Inquiry may be easier — it starts from one box where you describe the problem.

How It Works

One person,
start to production.

From shaping requirements to handling incidents after launch, the work does not change hands between stages. Taking on only part of it is fine too.

The form above is the fastest route for development work. These are here when they fit better.

FIVERR

Buy a fixed-scope gig

Secure payment, a stated delivery window, and a revision policy. Best when the scope is small and already clear. Larger builds are easier to start by email.

EMAIL

Write to me directly

If you already have a spec or a deck, attach it and send it over. Availability and rates for contract work are published on /work.
