Most AI agents fail in production. Not because the idea was wrong — but because very few people have actually mastered how to engineer production-grade AI agents. I design and build production-grade AI agents and automation systems with full architectural control. I take ownership of how systems behave once real users, real data, and real business constraints are involved. I’m Moamen Mohamed — an AI Agents Engineer with full-stack expertise. I’ve completed 22 jobs and 1,000+ hours of development work on Upwork, much of it built using AI coding assistants as part of my daily workflow. I’ve mastered tools like Cursor and Claude Code to accelerate delivery — while keeping judgment, system design, and architecture firmly under my control. I don’t treat AI as a feature. I treat it as a system that must be reliable, observable, and maintainable. What I build 🚀 • AI agents and chatbots engineered for production • RAG systems designed for accuracy and stability • Multi-agent workflows with clear orchestration • Internal AI tools teams actually use • Dashboards and operational interfaces • End-to-end AI SaaS products • Automations and integrations using n8n and no-code tools • Trading bots and financial-market automations built with the same discipline How I work 🎯 AI coding assistants and no-code tools are leverage — not authority. I move fast where appropriate, while staying fully responsible for architecture, agent behavior, and long-term maintainability. Speed comes from experience. Reliability comes from discipline. Why clients choose me 🔒 • 22 completed jobs and 1,000+ hours on Upwork • Deep experience across full-stack development, AI agents, and financial workflows • Selective engagement to protect quality and focus If you’re building the next great product — or want your business to operate faster and more efficiently by using AI properly — we’ll work well together.

I help companies design, build, and scale production-ready AI systems — LLM applications, RAG platforms, AI agents, NLP pipelines, machine learning models, workflow automations, and full-stack AI products. I’m an Expert-Vetted Upwork freelancer, ranked in the Top 1% of talent on the platform, with 12+ years of experience across AI, Data Science, Machine Learning, GenAI, NLP, MLOps, automation, and product engineering. On Upwork, I’ve delivered $400K+ in client work, 60+ jobs, and 8,600+ hours for startups, enterprises, and global clients. My strongest fit is with teams that need more than a prototype. I help clients move from idea to architecture, from architecture to implementation, and from implementation to reliable AI products that can be used in real business workflows. What I can help you build • LLM-powered applications, copilots, and AI assistants • Retrieval-Augmented Generation, or RAG systems • AI agents for research, automation, decision support, and internal operations • Chatbots connected to private company data, documents, and knowledge bases • NLP pipelines for classification, summarization, extraction, matching, and search • Semantic search and embedding-based recommendation systems • Fine-tuning, model evaluation, prompt engineering, and LLM workflow optimization • Machine learning models for prediction, forecasting, clustering, ranking, and anomaly detection • AI automations using Python, APIs, databases, cloud tools, vector databases, and orchestration layers • Technical architecture for AI SaaS products, internal tools, and AI operating systems Why clients work with me I combine senior AI leadership with hands-on technical execution. I can speak with executives about business value, work with product teams on scope and roadmap, and collaborate with engineers on architecture, implementation, deployment, and long-term maintainability. My background includes enterprise AI and Data Science work for companies such as HEINEKEN, Korn Ferry, and SKF, plus 60+ consulting projects across multiple industries and countries. I’ve led Data Science and AI initiatives, built production ML systems, designed GenAI and RAG solutions, and worked across both strategic AI adoption and hands-on engineering. I’m also a founder and full-stack product builder. As the founder, CEO, CTO, and solo developer of Vivai, I built a marketplace platform end to end, including mobile app, backend APIs, PostgreSQL database architecture, search, payments, authentication, partner workflows, cloud deployment, and production operations. Example projects I can support • Build a custom AI assistant over your company documents • Create a RAG system with retrieval quality, evaluation, monitoring, and guardrails • Automate business workflows using LLMs, APIs, scheduled jobs, and human-in-the-loop review • Improve an existing AI product for accuracy, reliability, speed, and cost • Develop NLP classification, extraction, summarization, or semantic search systems • Design the architecture for an AI SaaS product or internal AI platform • Turn a rough AI prototype into a stable, maintainable production system I’m a good fit if you need someone who can understand the business problem, recommend the right AI architecture, and build a practical solution with clean, maintainable implementation. If your goal is to build real AI products — not just demos — I can help you get there.
