I build and scale real production systems using Ruby on Rails, Node.js, Laravel, React, Next.js, MERN, PostgreSQL, MySQL, MongoDB, and AWS. Over fifteen years and more than thirty Upwork projects, I’ve delivered SaaS platforms, API architectures, e commerce systems, marketplace engines, cloud migrations, DevOps pipelines, and full stack applications that power real businesses, not prototypes. Rails apps struggling with performance. Node.js APIs breaking under traffic. Laravel backends falling apart during payment flows. React and Next.js front ends slowing down user activation. AWS setups missing DevOps structure. These are the systems I fix, redesign, and scale. I work as a system architect, not a “feature developer”. My experience spans Ruby on Rails, MERN stack, Node.js, Laravel, React, Next.js, AWS architecture, Docker, Kubernetes, CI/CD, and everything required to turn a fragile product into a stable, scalable platform. 🧠 𝐂𝐎𝐑𝐄 𝐄𝐍𝐆𝐈𝐍𝐄𝐄𝐑𝐈𝐍𝐆 𝐄𝐗𝐏𝐄𝐑𝐓𝐈𝐒𝐄 (𝐊𝐞𝐲𝐰𝐨𝐫𝐝 𝐎𝐩𝐭𝐢𝐦𝐢𝐳𝐞𝐝) 𝐅𝐮𝐥𝐥 𝐒𝐭𝐚𝐜𝐤 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭 React, Next.js, Vue, Node.js, Ruby on Rails, Laravel, MERN stack SPA architecture, component systems, REST APIs, GraphQL, micro front ends, modular monoliths, multi tenant SaaS.

Greetings! Alex here - a London-based UX/UI Designer, Full Stack Developer, and AI-focused product builder. I design, build, and optimise digital products with AI embedded across the full lifecycle - from research, UX, and interface design to development, automation, project delivery, and internal tooling. I also build custom AI solutions for my own workflows and help businesses implement AI in ways that are practical, commercially useful, and technically sound. My work sits at the intersection of product thinking, full-stack execution, and applied AI. That includes everything from AI-assisted delivery and automation to more advanced AI development such as RAG systems, LLM integrations, fine-tuning workflows, machine learning implementation, and custom AI-powered product features. Why work with me: • Expert-vetted professional trusted to deliver high-impact work across design, development, and AI-led execution • Top-Rated Plus with a strong track record of shipping thoughtful user experiences and reliable technical solutions • Among the top 1% in design and development, with AI deeply integrated into how I work and what I build • 99% of clients rate my work 5/5, reflecting consistent quality across strategy, execution, and communication What sets me apart: I combine design, engineering, and AI implementation in one end-to-end approach. 1. AI-enhanced design - I use AI to accelerate research, explore UX directions faster, test concepts, support content thinking, and improve design workflows without losing human judgement. 2. AI-supported development - I use AI across architecture, implementation, debugging, optimisation, QA thinking, and documentation to move faster while maintaining technical quality. 3. AI product development - I help build AI-native features and products, including chat experiences, AI assistants, internal copilots, recommendation flows, knowledge systems, and automation tools. 4. LLM and RAG expertise - I work with retrieval-augmented generation systems, document-aware AI workflows, vector-based search, prompt architecture, context pipelines, and knowledge-grounded assistants. 5.
