Haysam B.

I’m a Top Rated Plus Full-Stack & AI Engineer with 100% Job Success and $100K+ in Upwork earnings. I specialize in AI integration, AI agents, RAG, LLM applications, and AI-powered SaaS products. I work with startups, SaaS companies, and established businesses that want to build AI products or add AI to an existing application. I can take an AI feature from architecture and API integration through development, testing, deployment, and production. What I Build * AI-powered SaaS applications * AI agents and agentic workflows * RAG systems and knowledge bases * AI chatbots and conversational applications * LLM-powered features and assistants * AI-powered search and recommendations * Document AI and intelligent data extraction * AI workflow and business automation * OpenAI, Anthropic Claude, Gemini and other LLM integrations * Custom AI integrations for existing SaaS products My Technical Strength My advantage is that I’m not only an AI developer. I’m a senior full-stack engineer who can build the entire product around the AI. My core stack includes Next.js, React, TypeScript, Node.js, NestJS, PostgreSQL, Supabase, REST APIs, vector databases, LLM APIs and cloud infrastructure. That means I can handle everything from the AI layer to the surrounding application: databases, authentication, APIs, third-party integrations, subscriptions, performance, and production deployment. Projects I Work On * Adding AI capabilities to existing SaaS products * Building AI-powered products from scratch * Developing AI agents that interact with APIs, tools and business data * Building RAG systems over private company data * Integrating LLMs into existing applications and workflows * Building AI automation and intelligent business workflows * Architecting and scaling production AI applications Why Clients Hire Me I bring 6+ years of professional software engineering experience and have worked on complex SaaS products, multi-tenant platforms, integrations, analytics systems, and AI applications. I focus on writing maintainable code, making sensible architecture decisions, and building AI features that work reliably in a real production environment rather than stopping at a prototype. If you’re building an AI product, adding AI to an existing SaaS, or need an experienced engineer to integrate AI into your business, send me a message and tell me what you’re building.
