Hands-on notes about building software and writing on the AI-era web.

Contract Software Engineering

~/contract

Contract software engineering for AI-era web products.

I help founders and small teams ship practical AI-enabled web products, internal tools, and content-driven sites using TypeScript, React/Astro, and modern web infrastructure.

01

AI-enabled product features

Useful AI workflows inside real products — not demos for the sake of demos.

  • LLM API integrations
  • AI-assisted user workflows
  • internal copilots and automations
  • prototype-to-product implementation

02

Product engineering

Senior engineering capacity for small teams that need to ship polished product work.

  • React and TypeScript features
  • dashboards and admin tools
  • product polish and performance
  • API integrations and workflow improvements

03

Content-driven web systems

Fast, maintainable websites for founders, devtools companies, creators, and technical teams that publish.

  • Astro sites and technical blogs
  • landing pages and launch pages
  • content architecture
  • newsletter and site integrations

Who I work best with

  • founder-led startups
  • small SaaS teams
  • agencies that need senior engineering help
  • technical creators building products
  • teams that need shipping velocity before hiring full-time

How we can work together

  • short implementation sprints
  • part-time contracts
  • fixed-scope projects
  • agency subcontracting
  • technical product support for early-stage teams

Have a project where senior engineering help would move things forward?

Send me a short note with what you’re building, what you need help with, your rough timeline, and whether this is fixed-scope or ongoing.
