Hire a AI Integration Developer in United Kingdom
AI features only matter if they make your product measurably more useful. We add LLM chatbots, semantic search, document Q&A, and AI-assisted workflows into your existing React, Next.js, or SaaS app — with prompt caching, streaming, per-workspace quotas, and proper evals so you can ship without runaway costs or hallucinations.
UK founders and London-based scale-ups get senior React, Next.js, Shopify, and SaaS engineering at roughly half the rate of a London senior contractor (London senior devs average £500–£800/day). Full GMT afternoon overlap and a direct line to the engineer building your product.
Why founders in United Kingdom hire us for ai integration developer work

- Prompt caching + streaming-first architecture to keep costs and latency down.
- Per-workspace quotas, rate limits, and cost dashboards so AI never bankrupts your unit economics.
- Eval harness (golden sets + LLM-as-judge) so you can iterate on prompts without breaking prod.

Trusted by founders in India, USA & Australia
Average rating 5/5 from 6 clients shipping SaaS, Shopify, and custom web app builds.
“Sadik rebuilt our dispatch dashboard from a 6-second LCP to under 400ms and shipped a new driver mobile web app in four weeks. Most importantly, he understood the business logic — we did not have to explain it twice.”
“We needed a Next.js 14 App Router specialist for a 12-week retainer. Sadik stepped in on day one, owned the full auth + billing slice, and wrote the cleanest code our team has shipped all year. Fully remote from India with morning EST overlap.”
“Our Shopify store was averaging a 38 mobile PageSpeed score. Sadik rebuilt it as a headless Hydrogen storefront — 94 PageSpeed, 3× faster checkout, and revenue up 22% in the first month. Handled AEST mornings without complaint.”
Frequently asked questions — AI in UK
How does timezone work with UK clients?
We overlap with GMT/BST afternoons (your 1pm-6pm is our 6:30pm-11:30pm IST) for live standups, reviews, and pairing. Async work continues outside that window so progress never stalls overnight.
What currency and payment method do you accept from UK clients?
GBP via Wise (recommended) or USD via Stripe / direct bank transfer. Standard terms: 30% to start, 40% at milestone, 30% on delivery. UK-compliant invoicing with VAT notes where relevant.
Can you sign NDAs / MSAs with UK companies?
Yes. We sign standard UK-jurisdiction NDAs and MSAs before any code is written. IP assigns to the client on final payment.
Do you work with UK e-commerce brands on Shopify?
Yes. We build Shopify 2.0 themes and Hydrogen storefronts with multi-currency Shopify Markets (GBP / EUR / USD), Klarna / Clearpay integration, and Klaviyo flows tuned for UK retail.
Do you work with clients in India, the USA, and Australia?
Yes. I work with clients globally and have served teams across India, the USA, Australia, the UK, and Singapore. Indian clients are billed in INR; international clients are billed in USD (AUD on request).
How much does a custom SaaS or web app cost?
Custom web apps start at $10,000 for a focused MVP and scale with the feature set you choose on the quote estimator. Each additional feature (auth, payments, admin dashboard, real-time, etc.) adds $100. You get a full fixed quote before any work begins.
