LLM features that ship, with evals so they don't drift.

The local read
Why hiring a ai engineer in London is hard
London founders have access to deep fintech and gov-tech talent but the hiring cycle is brutal. Senior offers in the City clear £100K base plus equity that competes with Revolut and Wise. Local dev shops mostly serve enterprise — slow procurement, multi-quarter contracts, agency-of-record billing.
Different model: one senior engineer ships your build in two weeks, four-to-five-hour overlap with our working hours, billed in USD. Open Banking via TrueLayer or GoCardless for fintech. Next.js + NestJS + Postgres for SaaS. Flat-price quote in 24 hours. Code in your GitHub from commit one.
A senior ai engineer here is a ~$309K year-one outlay after benefits, payroll tax, and the 60–90 day search. We're a $8,000+ flat engagement that starts inside seven days.

Why this beats a hire
One AI-native engineer.
The output of a team.
One senior ai engineer plus AI agents now ships what four engineers used to. Same code quality, half the cost, three-week timelines instead of three months. Built for pre-seed to Series A founders in London who need to ship before the next round closes.

The work, concretely
What we'd own day to day
The same scope you'd hand to a salaried ai engineer, owned end to end on a flat-price engagement. No coordination overhead, no junior-on-the-bench, no estimation theatre.
- Chat / agent UI with streaming, interrupt, retry, citations done right
- RAG: chunking, embeddings, hybrid search, reranking, citation-required prompts
- Multi-provider routing via Vercel AI Gateway — primary + fallback + cost rules
- Evals as a CI gate, not a vibe check — held-out test set, regression alerts
- Cost observability — token spend per route, model tiering, caching
Stack we use
Defaults — we deviate when the project demands it, not because something is fashionable.
