Engineering services that ship.
Eleven disciplines under one roof. We handle the work from backends and mobile through QA, AI, games, AR/VR, and blockchain on whichever stack your problem needs.
- Custom Software DevelopmentNode · Go · .NET · PythonWe build backends, data platforms, and integrations that fit your stack. Same engineers from kickoff to launch.
- Staff AugmentationContract · FTE · Senior+Senior engineers who join your standup on week one. We vet them, you keep them.
- E-commerce DevelopmentShopify · Headless · MagentoHeadless storefronts and checkout rails that hold up when traffic hits 10x.
- Cloud & DevOpsAWS · K8s · TerraformIaC, observability, CI/CD, cost guardrails. Your on-call rotation gets a quieter pager.
- UI/UX DesignFigma · Motion · SystemsDesigners embedded inside the engineering pod. Figma files match what ships.
- Mobile ApplicationsSwift · Kotlin · RNNative iOS and Android, React Native, Flutter. Plus the release engineering most shops skip.
- QA ServicesPlaywright · Cypress · AppiumExploratory, regression, API contract, device-lab, and performance testing. QA sits in your dev pod, not at the end of the line.
- Agentic AILangGraph · Claude · RAGAgents, RAG pipelines, tool-using LLM stacks. We wire in evals, guardrails, and cost caps before you ask.
- GamesUnity · Unreal · LiveOpsMobile F2P, hyper-casual, multiplayer, and LiveOps backends. We build for week four, when most launches stall.
- AR / VRVision Pro · Quest · WebXRVision Pro, Quest, HoloLens, and mobile AR for training, visualisation, and industrial twins. Built for production deployment.
- BlockchainSolidity · EVM · SolanaSmart contracts, L2 rollups, wallet and custody integrations. Audit-grade engineering, because on-chain bugs are forever.
AI development, built to run in production.
Agents, generative AI, LLM integration, chatbots and AI consulting, engineered with the same discipline as the rest of our work: evaluated before launch, guarded in use and costed per request.
Explore AI development- AI agent developmentAgents that plan, call your tools and hand off to people when unsure.
- Generative AI developmentText, image and document generation built into your product.
- LLM integration and RAGLanguage models wired into your systems and answering from your documents.
- AI chatbot developmentCustomer and internal assistants that answer from your own data.
- AI consultingUse-case selection, data readiness and governance before you build.

How we deliver
Engineer. Ship. Outlast.
Every Cloudini engagement runs through the same five phases, each with named artefacts and a concrete time estimate.
Discover
Discovery brief (what we will build, why, and for whom). Risk register with named owners and mitigations.
Design
Working clickable prototype of the critical flows. Architecture decision log (ADRs) with alternatives considered.
Build
Production deployments on a measurable release cadence. Automated test suite with coverage targets per module.
Run
Live SLO dashboard with error-budget burn tracking. Incident post-mortems with action items and owners.
Evolve
Quarterly outcome review vs the original business brief. Updated risk register, architecture log and roadmap.
Every sector, one way of working.
From a regulated bank to a community health programme, our method is the same. The rigor scales with the stakes. You get no surprises in week eight.
London.

Tools, chosen by the people who maintain them.
No framework ideology. We pick what fits the problem, write the decision down, and revisit it every year.

Clients
What partners tell us.
Client feedback on the engineering work behind these projects.
We are a mental health charity and not tech-minded. We needed to improve our patient registration system but wanted a company that we can relate to. Hassan took the time to meet with me and patiently went through our process to find a personalised solution for us. Hassan's team did a great job streamlining our process and connected our registration system to our patient management software. Whenever we have a glitch, they resolve this quickly.
Tien KueiCEO · Power to Live Foundation
Our journey with them has been nothing short of exemplary, far exceeding our initial expectations.
Robert McPhersonManaging Director · RBM Global Ltd
One of their strengths is quickly building out a multi-disciplinary team to work on the development and delivery of features with different technical requirements. Their support has allowed us to accelerate our development work without building an internal team. They have also worked seamlessly with other third parties both during the acquisition of Dragonfly and development of our mobile app.
Rebecca PalserCOO · Dragonfly
As well as being exceptional technically, they consistently invest the time to understand the product and suggest how it can be enhanced and improved.

We offer three engagement models. (1) Dedicated engineering teams: a cross-functional pod working long-running on your product, staffed in 72 hours. (2) Offshore development centre: a branded engineering function inside your company, operational in four weeks. (3) Staff augmentation: vetted senior engineers embedded in your existing team, on the keyboard within 72 hours.
Every sector we serve, including financial services, healthcare, retail, logistics, telecom, energy, public sector, education, manufacturing, real estate, travel, legal, and HR. The engineering discipline transfers across all of them. Regulatory and domain knowledge is what we specialise in per sector.
Polyglot by design. Go, Python, TypeScript, Java, Kotlin, C#, Rust, Swift on the application side. AWS, GCP, Azure on infrastructure. Postgres, Snowflake, Kafka, and the full AI/ML toolchain. We pick the stack to fit your problem and existing estate, not a vendor relationship on our side.
Send us a message through the contact form or book a 30-minute call. We reply within one working day with a real person, not a drip campaign. First call is discovery. Your problem, our fit, and whether we're the right partner. No sales pressure, no filler decks.
Let's build from here.
Thirty minutes with an engineer who builds. No sales, no drip campaign. If we're the wrong fit we'll tell you and point you somewhere better.
