Expertise / Engineering services

Engineering expertise for existing and evolving software.

I provide direct senior engineering involvement in backend development, application architecture, integrations, cloud infrastructure and production AI. I work with software companies and engineering teams on defined responsibilities inside real products.

Five primary areas of work

Who this is for

I work with small and medium-sized software companies, SaaS teams, CTOs and engineering leaders who need senior engineering responsibility without adding another permanent role. Boutique consultancies can also bring me into a bounded client workstream.

An existing codebase or architecture is welcome. A rewrite is not a prerequisite; we can work within the current system and agree where a change is warranted.

Ways to engage

  • Weekly capacity for ongoing work in an existing team.
  • A fixed-scope project with defined deliverables and acceptance criteria.
  • An optional paid technical assessment when the project boundary is unclear.

Direct contact

Weekly and project work depends on current capacity and mutual agreement. You do not need a complete specification to start a conversation.
