# Websites, apps and the systems behind them. > Marketing sites, web apps, native iOS and Android apps in React Native, backends and data pipelines. Fast, measured, and handed over with the code. Page: https://adjltechnology.com/services/software/ Updated: 2026-11-12 Websites & Apps Marketing sites, web apps, native iOS and Android apps, APIs and data pipelines. We build them fast to load, strict about security and easy for the next developer to read. Then we hand over the repository. [See this page measured](https://adjltechnology.com/services/software/#telemetry) [Talk to Daniel](https://adjltechnology.com/services/software/#contact) - **Inputs:** A problem, a brand and whatever already exists - **Builds:** Sites, web apps, native apps, APIs, pipelines - **Measures:** Speed budgets, security headers, tests that pin outputs - **Hands over:** The repository, the tests and the build guards People read the top layer, crawlers follow the middle one and machines parse the bottom one. What we ship ## From the page to the pipeline. ### Marketing sites Static HTML that renders before any script runs, a strict content policy and structured data on every page. This site is one. ### Web apps Customer portals, internal tools and dashboards. Quick to open, honest about loading, and clear about where every number came from. ### Native apps iOS and Android from one Expo and React Native codebase. Logic that matters is shared with the web version and pinned by tests, so the phone and the website can’t disagree. ### Backends and APIs Serverless and edge functions, scheduled jobs and the APIs your front ends call. Every function checks who’s asking before it spends anything. ### Data pipelines Daily jobs that fetch, check and store data. They record when each fact was true, and they fail loudly when a source changes shape. Live readout ## This page, measured. The readout below comes from your browser’s own performance APIs. We didn’t type any of the numbers. If your browser doesn’t report a metric, the field says so instead of guessing. Shared logic ## One engine, two platforms. The investor app we built for ADJL Capital runs its underwriting engine on the phone. The engine files are the same ones the website runs, byte for byte, and tests hold both to the same answers. 1. The website and the app run the same engine files. 2. Each module is copied byte for byte. None of them is ported. 3. Golden scenarios run against both copies, so any drift fails a test. 4. The phone needs no network to compute. Take it offline and it still recomputes. - [How the app works](https://adjltechnology.com/work/mobile-app/) Build guards ## Checks your team inherits. Every site we ship comes with checks that fail the build. Dead CSS, broken links, missing structured data, pages over budget and copy that claims what it can’t back up. Your team gets the checks along with the code. Handover ## What you get at the end. Everything needed to run it without us. - The repository, with its history - Tests that pin the outputs that matter - The build guards, already wired in - Deployment config and security headers - A runbook for when something breaks - Design tokens, so the next page matches Proof ## Software that’s running now. Each of these runs today. - [How the app works](https://adjltechnology.com/work/mobile-app/) - [How the private site’s lock works](https://adjltechnology.com/work/private-site/) - [How this site is built](https://adjltechnology.com/work/this-site/) Fair questions ## Questions about software builds. ### Which stack do you use? Whatever fits the job. This site is Vite and plain TypeScript with no framework. The investor app is Expo and React Native. Backends run as serverless and edge functions. The scope explains each choice. ### Can you work with our existing site? Yes. Most of the time the cheapest fix lives inside what you already have. We work in your repository, to your conventions, and leave it easier to change than we found it. ### Do you maintain what you build? The handover is built so your own team can take it over. If you’d like us to stay on, that’s a separate written agreement with its own scope. Start here ## Tell us what’s slow, or what can’t be found. One paragraph is plenty. Tell us what you want built, the step that costs the most, or the page that should rank and doesn’t. If you know why the obvious fix hasn’t worked, say that too.
