--- Headless CMS Fullstack Developer | 11 CMS Platforms | React, Vue, Next.js, Nuxt I build production-ready websites and web applications on top of headless CMS systems — and I've done it across more platforms than most developers will touch in a career. My core project is a CMS-agnostic frontend generator that supports 11 platforms: Contentful, Sanity, Storyblok, DatoCMS, Strapi, Directus, Payload, Prismic, Hygraph, WordPress, and TYPO3. Switch your CMS by changing one environment variable — the frontend adapts automatically. Every generated project ships with full test coverage, type safety, and CI/CD out of the box. What that means for you: I don't just connect a CMS to a template. I understand content modeling, API design (REST + GraphQL), preview workflows, webhook integrations, and how to structure a frontend so your editors can actually work with it — regardless of which CMS you're on. Tech stack: - Frontend: React, Vue 3, Next.js, Nuxt 4, React Native - Backend: Node.js, Express, PostgreSQL, Supabase, Docker - Languages: TypeScript (strict), JavaScript — Top 1% on Codewars - Shopify Storefront API for content-commerce setups Beyond CMS — products I've shipped: - A Gantt-based project management platform (client project → SaaS, 90+ API endpoints, 23 pages, Docker deployment) - A cross-platform fitness app with AI-powered photo verification (React Native, Supabase, 65 screens, 3 languages) - An iOS/watchOS cold exposure app published on the App Store (Swift, MDX marketing site, Vercel) - A voice AI companion across 5 apps and 4 platforms (Swift, Kotlin, React Native, Node.js) Headless CMS integration is my sweet spot, but my project history speaks for itself: SaaS platforms, cross-platform mobile apps, AI-powered features, App Store products. If it runs on JavaScript/TypeScript, I can build it — and ship it with the same quality standards. M.Sc. in Communication and Information Sciences. Based in Berlin.

Hi, I’m Mohannad — a Full-Stack Developer and QA Automation Engineer focused on one thing: helping teams ship fast without breaking things in production. Most teams either build fast and deal with bugs later, or move slow trying to avoid them. I solve both problems by combining development and QA into a single, scalable workflow. I’ve worked on enterprise and government systems where quality, reliability, and compliance are non-negotiable. What I do Build Develop scalable SaaS applications using React, Node.js, and Firebase Design systems that support real users, multi-role access, and growth Implement authentication, dashboards, and Stripe billing (subscriptions & trials) Test & Protect Build automation frameworks using Playwright, Cypress, and Selenium End-to-end, API, and regression testing that catches issues early CI/CD integration so every release is validated before it goes live Automate UiPath workflows to eliminate repetitive manual processes Data extraction, validation, and reporting (PDFs, Excel, APIs) Ensure Compliance WCAG & Section 508 accessibility testing (JAWS, Axe, WAVE) Experience with compliance-heavy systems where standards matter Why clients hire me I don’t just “test” — I prevent production issues before they happen I build systems that are scalable, testable, and maintainable I think like an engineer, not just a tester Clear communication, fast execution, no hand-holding needed Recent Work Built a SaaS dashboard with authentication, Stripe billing, and real-time data Developed a Playwright automation framework with CI/CD integration Automated business workflows using UiPath, reducing manual effort Tech Stack React, Next.js, Node.js, Express, Firebase Playwright, Cypress, Selenium, Appium Postman, REST Assured, SoapUI UiPath, SQL, GitHub, Jenkins, Azure DevOps Let’s work If you need someone who can build your product and ensure it works correctly at scale, I can help.

I write the code that ships. Ten years of production software, about half of it now spent building LLM features and agents into real products, the other half building the products themselves. Where I usually get called in: - The prototype that impressed everyone six months ago is still a prototype. Nobody had time to close the gap to production. - You have a working web app and no mobile presence, and a native rebuild costs more than the app is worth. - You hired an AI advisor and got a strategy deck when you needed a pull request. - Your engineers know the product but have never shipped against an LLM API, so the AI work keeps sliding down the roadmap. Every project is run by the person writing the code. What I build: - Cross-platform mobile. Capacitor and Ionic apps built on top of an existing web codebase, taken through iOS App Store review and out the other side. Push, deep links, native device APIs, persistent auth, offline states, and the review notes that stop Apple calling it a wrapper. - AI agents for research, support, internal ops, and customer-facing workflows. Tool use, retrieval, memory, guardrails, and the plumbing that keeps them alive when the API times out at 3am. - LLM features inside your existing product: generation, classification, extraction, summarization, search. Production prompts, caching, retries, fallbacks, cost controls, and evals so you can tell when a change made things worse. - Web apps end to end. Next.js and Vue front ends, Node and Python back ends, Postgres and Supabase underneath. Auth, queues, webhooks, background jobs, CI, deploys. Most "AI projects" are 80% normal backend work, and that is usually where they break. - MVPs from nothing to launched. Backend, frontend, prompts, infrastructure, app store, shipped in weeks. Why me: - Engineer first. I read your codebase and work inside your conventions instead of dropping a parallel system next to it. - Two and a half years on the same Capacitor app, built from zero, live on the App Store and still shipping to it. I have been building hybrid mobile since the Cordova days, so I know which parts of this approach are fine and which ones bite. - Deep on the Anthropic and OpenAI SDKs: tool use, agent loops, MCP servers, prompt caching, batch APIs, structured outputs, citations. I have already hit the failure modes you would find in production. - You own everything at the end. Your repo, your keys, your infrastructure, with tests and a README your team can pick up. No black box, no monthly lock-in. Tech I use: TypeScript, Python, Node, Next.js, React, Vue/Nuxt, Capacitor, Ionic, PostgreSQL, Supabase, Docker. Anthropic API, Claude Agent SDK, OpenAI API, MCP, n8n. I adapt to your stack instead of forcing mine. How it works: Smaller integrations and features ship in 1 to 3 weeks. App builds, agent work, and MVPs usually run 4 to 8 weeks. You get a fixed scope, timeline, and price after a short discovery call, not a rolling estimate. Tell me what you want to build and what done looks like. I'll tell you whether it's a fit and roughly what it takes to ship it.
