## Services

- [Website development & custom CMS](https://mail.rscs.ae/services/website-development-custom-cms): Marketing sites that load in under a second, with an editor your team drives without raising a ticket. Typical timeline: 4–8 WEEKS.
- [E-commerce development](https://mail.rscs.ae/services/ecommerce-development): Storefronts where payments settle, stock reconciles and the checkout survives a campaign spike. Typical timeline: 6–12 WEEKS.
- [Web applications](https://mail.rscs.ae/services/web-applications): Dashboards, portals and internal platforms the business actually runs on, not another abandoned tool. Typical timeline: 8–16 WEEKS.
- [AI-based solutions](https://mail.rscs.ae/services/ai-based-solutions): Retrieval assistants, agent workflows and model plumbing with evals attached, so you can tell when it drifts. Typical timeline: 6–14 WEEKS.
- [Mobile app development](https://mail.rscs.ae/services/mobile-app-development): iOS and Android built once or built native — we'll say which one your budget and roadmap argue for. Typical timeline: 10–18 WEEKS.
- [SEO](https://mail.rscs.ae/services/seo): Technical debt cleared first, then content built around the queries that actually convert in your market. Typical timeline: RETAINER.
- [Social media marketing](https://mail.rscs.ae/services/social-media-marketing): Paid social and creative built around one number you agreed in advance — not a monthly deck of impressions.

## Technologies

Each page covers what the technology is, when we choose it, when we deliberately do not, what we build with it and what it costs you.

- [React](https://mail.rscs.ae/technologies/react): React is a JavaScript library for building user interfaces out of reusable components. We use it for dashboards, portals and any screen a person spends hours in — anywhere the interface has enough state that rebuilding the page on every click would feel wrong.
- [Next.js](https://mail.rscs.ae/technologies/nextjs): Next.js is a React framework that renders pages on the server before sending them to the browser. We use it for marketing sites and customer-facing applications where search ranking and first-load speed decide whether the project pays for itself — typically shipping in four to eight weeks.
- [Vue](https://mail.rscs.ae/technologies/vue): Vue is a JavaScript framework for building interfaces, comparable to React but easier to learn and simpler to add to a page that already exists. We reach for it when a client's own developers will maintain the front end, or when only part of a server-rendered page needs to be interactive.
- [Nuxt](https://mail.rscs.ae/technologies/nuxt): Nuxt is a framework built on Vue that renders pages on the server before sending them to the browser. It exists for the same reason Next.js does: a public page rendered only in the browser is slow for customers and close to invisible to crawlers.
- [TypeScript](https://mail.rscs.ae/technologies/typescript): TypeScript is JavaScript with a type system layered on top. It catches a whole category of bug — a missing field, a wrong shape, a value that can be null — while the code is being written rather than after a customer finds it. We use it on every JavaScript project without exception.
- [Tailwind](https://mail.rscs.ae/technologies/tailwind): Tailwind is a CSS framework where styles are applied through small utility classes rather than hand-written stylesheets. Its real value is that the available spacing, colours and type sizes come from your design tokens, so a developer in a hurry cannot invent a fourteenth shade of grey.
- [Angular](https://mail.rscs.ae/technologies/angular): Angular is a complete front-end framework from Google. Unlike React, it makes the architectural decisions for you — routing, forms, HTTP, testing all come as part of it. That is a liability on a small project and an asset on a large one with many developers.
- [Node.js](https://mail.rscs.ae/technologies/nodejs): Node.js runs JavaScript on the server. We use it when a system needs to hold many connections open at once — live tracking, chat, notifications — or when the team already writes JavaScript on the front end and one language across the stack is worth more than any framework difference.
- [Laravel](https://mail.rscs.ae/technologies/laravel): Laravel is a PHP framework for building web applications and custom content systems. We use it when a project needs an admin panel, real business rules and hosting that works anywhere PHP does — which in the GCC often means a cPanel plan the client already pays for.
- [Django](https://mail.rscs.ae/technologies/django): Django is a Python web framework built around the database. Define your data model and it generates the tables, the forms and a working admin interface. We use it for data-heavy internal systems and for anything that sits next to Python machine-learning work.
- [FastAPI](https://mail.rscs.ae/technologies/fastapi): FastAPI is a Python framework for building APIs. It validates every request against a typed schema and generates interactive documentation from that schema automatically. It is what we put in front of a machine-learning model when the rest of the application lives elsewhere.
- [.NET](https://mail.rscs.ae/technologies/dotnet): .NET is Microsoft's application platform, using C#. It is genuinely fast, strongly typed and has long-term support dates published years in advance. We use it where a client already runs Microsoft infrastructure, or where procurement requires a platform with a named vendor behind it.
- [Go](https://mail.rscs.ae/technologies/go): Go is a compiled language from Google designed for network services. It produces a single executable file with no runtime dependencies, starts in milliseconds and uses very little memory. We use it for focused, high-traffic services rather than for whole applications.
- [GraphQL](https://mail.rscs.ae/technologies/graphql): GraphQL is a query language for APIs. Instead of many endpoints each returning a fixed shape, there is one endpoint and the client describes exactly which fields it wants. It is worth the extra complexity when several very different clients consume the same data.
- [Swift](https://mail.rscs.ae/technologies/swift): Swift is Apple's language for iOS apps. Building natively costs more than cross-platform because Android needs its own codebase, and it is the right call when the app depends on Apple hardware features or when the interface has to be indistinguishable from a first-party app.
- [Kotlin](https://mail.rscs.ae/technologies/kotlin): Kotlin is Google's official language for Android. Building natively is the right call when Android dominates your audience — which across much of the GCC it does — and when the app has to work well on inexpensive devices as well as flagships.
- [React Native](https://mail.rscs.ae/technologies/react-native): React Native builds iOS and Android apps using React. Unlike Flutter it uses each platform's real native controls, so the app feels native on both. Its biggest advantage is organisational: a React web team can build and maintain it.
- [Flutter](https://mail.rscs.ae/technologies/flutter): Flutter is Google's toolkit for building iOS and Android apps from one codebase. It draws its own interface rather than using each platform's native controls, which means the app looks and behaves identically on both — and ships in roughly 60% of the time two native apps would take.
- [Python](https://mail.rscs.ae/technologies/python): Python is the language of data and machine learning. We use it for anything involving models, document processing or analysis — and generally as a service alongside the main application rather than as the application itself.
- [LangChain](https://mail.rscs.ae/technologies/langchain): LangChain is a Python framework for building applications around language models — chunking documents, storing embeddings, retrieving relevant passages and chaining steps together. We use its retrieval and evaluation pieces and deliberately avoid its heavier abstractions.
- [OpenAI](https://mail.rscs.ae/technologies/openai): OpenAI provides hosted language, vision and speech models over an API. We integrate them for classification, extraction, drafting and transcription — always behind a spend cap, always with an evaluation set, and always with a fallback for when the API is down.
- [Anthropic](https://mail.rscs.ae/technologies/anthropic): Anthropic's Claude models are hosted over an API like OpenAI's. We choose them when documents are long enough that context size decides the design, or when the assistant is better off declining to answer than guessing.
- [pgvector](https://mail.rscs.ae/technologies/pgvector): pgvector is a PostgreSQL extension that stores and searches embeddings. It means the vectors live in the same database as the records they describe, in the same transaction and the same backup — which removes the consistency problem a separate vector database introduces on day one.
- [Whisper](https://mail.rscs.ae/technologies/whisper): Whisper is OpenAI's speech-to-text model. It handles accented English, Gulf Arabic and switching between the two mid-sentence better than most alternatives, which is what makes it usable for voice features in this region.
- [Custom CMS](https://mail.rscs.ae/technologies/custom-cms): A custom CMS is an editing interface built for one site's content model rather than for every possible site. If you sell services, the editor has a service type with a timeline and a price band — not a blank page and a drag-and-drop toolbar.
- [WordPress](https://mail.rscs.ae/technologies/wordpress): WordPress runs a large share of the web and is genuinely good at publishing articles. We build custom themes on it with a deliberately short plugin list, because plugin weight is the reason most WordPress sites end up slow.
- [Shopify](https://mail.rscs.ae/technologies/shopify): Shopify is hosted e-commerce. It handles payments, PCI compliance, fraud screening and scaling, and charges a monthly fee plus a transaction cut. For most retailers that is a far better trade than owning a payment stack.
- [WooCommerce](https://mail.rscs.ae/technologies/woocommerce): WooCommerce turns WordPress into a shop. It charges no transaction fee and gives complete control over pricing and checkout, in exchange for you owning the hosting, the security and the PCI scope.
- [Strapi](https://mail.rscs.ae/technologies/strapi): Strapi is a self-hosted headless CMS: editors manage content in its admin, and it serves that content as an API to whatever consumes it. It earns its place when a website, a mobile app and possibly a partner all need the same content.
- [Sanity](https://mail.rscs.ae/technologies/sanity): Sanity is a hosted headless CMS with an unusually good editing interface — multiple people can work on the same document at once, and the editor is itself configurable. It suits editorial teams publishing continuously.
- [PostgreSQL](https://mail.rscs.ae/technologies/postgresql): PostgreSQL is a relational database with a reputation for correctness. It also handles JSON, full-text search, geospatial data and vector search natively, which regularly removes the need for a second datastore.
- [MySQL](https://mail.rscs.ae/technologies/mysql): MySQL is the database included with virtually every shared hosting plan. For content sites, shops and most business applications it is entirely sufficient, and its availability decides more architectures in this region than its features do.
- [MongoDB](https://mail.rscs.ae/technologies/mongodb): MongoDB stores documents rather than rows, with no fixed schema. It suits data whose shape genuinely varies between records — event logs, third-party payloads, product specifications that differ by category.
- [Redis](https://mail.rscs.ae/technologies/redis): Redis keeps data in memory, which makes reads dramatically faster than disk. We use it for caching, sessions, rate limiting and job queues — never as the permanent home for data that matters.
- [AWS](https://mail.rscs.ae/technologies/aws): AWS is the largest cloud platform, with regions in Bahrain and the UAE. We use it when data must stay in the region, when scale is genuinely variable, or when a client already runs there — not by default for a website.
- [Azure](https://mail.rscs.ae/technologies/azure): Azure is Microsoft's cloud, with a UAE region. Its advantage is integration: if your staff sign in with Microsoft accounts and your reporting is Power BI, an Azure-hosted application fits without an adapter layer.
- [Docker](https://mail.rscs.ae/technologies/docker): Docker packages an application together with everything it needs to run — the language version, the extensions, the system libraries — into a container that behaves identically on a laptop, in CI and in production.
- [Kubernetes](https://mail.rscs.ae/technologies/kubernetes): Kubernetes orchestrates containers across many machines — scheduling, scaling, restarting and networking them. It is genuinely powerful and genuinely heavy, and most projects that adopt it would have been better served by something simpler.
