Full Stack AI Developer | AI Agent Developer | AI Automation Expert

Grow your business without letting manual work grow with it. I build AI agents, AI automation, and full-stack applications that help your team handle more clients, respond faster, and spend less time on repetitive tasks. Whether you want to automate operations, integrate AI into existing software, or launch a complete web application, I turn your requirements into practical, working systems. I’m Karim, a Full Stack AI Developer focused on AI Agent Development, Workflow Automation, API Integration, and custom business software. My background includes internal tools, operational dashboards, SaaS applications, and software supporting HR and e-learning processes at Continental. 🎯 WHAT WE CAN ACHIEVE • More capacity for clients and projects by reducing repetitive administrative work. • Faster responses and more consistent follow-up through connected workflows. • Less copying between spreadsheets, emails, CRMs, and business tools. • Clearer visibility into operations through centralized dashboards and reporting. • A working application that turns your idea into something customers or employees can use. 🛠️ WHAT I CAN BUILD FOR YOU ◆ AI Agents & Business Assistants Custom AI assistants that summarize information, draft responses, process documents, and perform defined tasks through connected tools and APIs. Human review and approval can be built into steps that need your team’s judgment. ◆ AI Automation | n8n, Make & Zapier Automated workflows for client onboarding, CRM updates, task assignment, follow-ups, notifications, and reporting. I use n8n, Make, Zapier, and custom code to connect your applications and reduce manual coordination. ◆ AI Integration & Generative AI Applications Integrate OpenAI and Claude into your existing software or a new application. Add document analysis, text generation, classification, summarization, and structured data extraction. ◆ MCP Integration & AI Tool Connections Connect AI assistants to business tools, APIs, and data sources through the Model Context Protocol (MCP). Build MCP integrations and servers that let assistants retrieve information and perform defined actions with appropriate permissions. ◆ CRM Automation & API Integration Connect website forms, CRM records, databases, and third-party services. Capture enquiries, synchronize information, assign tasks, and trigger follow-up actions through REST APIs and webhooks. ◆ Custom Internal Tools & Dashboards Build tools for managing clients, projects, KPIs, reporting, and internal processes. Give your team a shared workspace with the permissions, views, and functionality their roles require. ◆ Full-Stack Development & SaaS MVPs Develop SaaS products, web applications, client portals, and admin dashboards using React, Next.js, TypeScript, and Supabase. I handle frontend, backend logic, databases, integrations, and deployment—with or without AI features. 💡 WHAT YOUR SYSTEM COULD DO → Turn a new enquiry into a CRM record, an assigned task, and a follow-up reminder. → Extract information from incoming documents for your team to review. → Prepare a draft response using the context of an incoming message. → Bring operational data into one dashboard for easier reporting. → Replace a spreadsheet-based process with a custom application. → Connect an AI assistant to your business tools through MCP. 🤝 WHY CHOOSE ME? ◆ Full-stack engineering behind your AI implementation I build the interface, database, application logic, and integrations around your AI features, giving you a complete system your team can use. ◆ Experience with business operations My background in internal tools and business applications helps me understand reporting, permissions, team workflows, and everyday usability. ◆ Development guided by your goals We define what you want to improve—manual steps, turnaround time, visibility, or capacity—and use that to guide the scope. ◆ Direct communication and clear milestones You work directly with me, with agreed deliverables and progress updates throughout the project. ◆ Practical testing and handover I test real scenarios and provide documentation, walkthroughs, and team training so you can use the system confidently. ⚙️ TECHNOLOGIES & TOOLS • AI: OpenAI API, ChatGPT, Claude • Automation: n8n, Make, Zapier • AI Tool Connections: MCP, Model Context Protocol, MCP Servers • Frontend: React, Next.js, JavaScript, TypeScript, Tailwind CSS • Database & Backend: Supabase, PostgreSQL, application APIs • Integrations: REST APIs, Webhooks, Stripe, Twilio, Resend • Deployment: Vercel 🚀 LET’S DISCUSS YOUR PROJECT Send me a message with what you want to build, the process you want to improve, and the tools you currently use.
