A typo in a URL, or a menu that changes weekly, otherwise means reprinting every code already in the world. Dynamic codes that store a short link instead of the destination, so the destination can be edited later and every scan can be counted. A companion Cloudflare Worker lets people self-host that redirect layer with signed lists and an allowlist. - [Transcend](https://abdurrahmanhassan.com/story/#transcend): People described what they wanted in ordinary language, but acting on it meant many separate steps in many separate tools. The gap between intent and a completed task was entirely manual. An agentic platform where natural-language intent is turned into automated multi-step tool execution over MCP servers, with dynamic state orchestration and a drag-and-drop canvas for arranging the work. - [BoxBuy](https://abdurrahmanhassan.com/story/#boxbuy): One platform had to serve caterers arranging meals, admins overseeing everything, and property partners managing rooms and guests. Each group needed different screens, permissions, and data, while sharing the same codebase and database. Four connected panels on one multi-tenant core. Container and CI/CD work cut infrastructure cost by 35% and deployment errors by 90%, while the team shipped releases five times faster. ## Skills - Languages: TypeScript, JavaScript, Python, SQL, HTML5, CSS3, C++, Java. - Frontend: Next.js, React, SvelteKit, Vue, Storyblok, Redux Toolkit, Tailwind CSS, Material UI, Framer Motion, Ionic, Capacitor. - Backend & APIs: Node.js, NestJS, Express, Fastify, REST APIs, GraphQL, MCP. - Databases & BaaS: PostgreSQL, Supabase, MongoDB, Firestore, Redis, MySQL, Appwrite. - Cloud & DevOps: GCP, AWS, Docker, GitHub Actions, Vercel, Cloudflare Workers, NGINX, Linux. - AI & agentic systems: MCP (Model Context Protocol), Intent-to-action pipelines, LangChain, LangGraph, Tool calling & orchestration, OpenAI API, Hugging Face, Gemma, Ollama, Scikit-learn, Whisper, ElevenLabs, OpenCV, PyTorch. - Payments & integrations: Stripe, PayU, Imoje, Twilio, WhatsApp Business API, Google Ads API, Notion API, Shopify. - Testing & tooling: Playwright, Jest, Postman, Git, GitHub, Ahrefs SEO. ## Contact - Email: abdurfreelance@gmail.com - Phone and WhatsApp: +92 311 2910773 - Résumé (PDF, opens in a new tab): https://abdurrahmanhassan.com/abdurrahman-hassan-resume.pdf - LinkedIn: https://www.linkedin.com/in/abdurrahman-hassan/ - GitHub: https://github.com/Abdurrahman-Hassan ## Optional - [Full text of this site](https://abdurrahmanhassan.com/llms-full.txt): every role, project, and case study in one plain-text document. - [Sitemap](https://abdurrahmanhassan.com/sitemap.xml): the canonical URL list.
