AI Agent Developer and AI engineer building AI RAG systems and AI integration for production, not demos — AI Agent Developer work is what I do daily. Senior Full Stack Developer working full-time as an AI Agent Developer, AI engineer, and AI integration specialist, with AI RAG pipelines and AI integration into real SaaS products as my core focus. Looking for an AI Agent Developer, AI engineer, or AI RAG specialist for AI integration work? Let's talk. What I do as an AI Agent Developer and AI engineer: As an AI Agent Developer, I build agentic workflows (LangChain, LangGraph) — from single-task bots to autonomous multi-step assistants; this is the core of my AI Agent Developer practice. AI RAG systems on Pinecone / pgvector, tuned for retrieval accuracy — AI RAG is not a side skill, it's a primary focus alongside AI engineer work. AI integration and api integration connecting AI machine learning features into existing products — OpenAI API, Claude API, WhatsApp Business API, automation via n8n; AI integration is where most of my recent work sits. Full-stack delivery when the ai feature needs a real product around it: React, Next.js, Node.js/NestJS, PostgreSQL. AI integration extends into mobile and location-aware features — gps, gps app, and gps tracking logic on React Native, with Swift interop for native iOS handling when a project needs it. Selected work as an AI Agent Developer and AI RAG / AI engineer: DrWally — AI automation platform for e-commerce: as an AI Agent Developer I built the AI bot creator, plus official WhatsApp Business campaigns and webhook-driven order/shipping automation — a direct AI integration case. Opesync (AI Onboarding Buddy) — AI workforce platform where an autonomous agent, built using AI Agent Developer methods and ai machine learning techniques, handles onboarding; another clear AI RAG and AI integration deliverable, with a real-time dashboard for teams of 100-1000+. Background as a software engineer and data scientist-adjacent developer, now focused on AI engineer work: Before specializing as an AI Agent Developer and AI engineer, I spent years as a software engineer delivering 30+ SaaS platforms. That foundation now supports my AI RAG and AI integration work, including some computer vision experimentation for e-commerce image pipelines. Tech stack for AI Agent Developer / AI engineer / AI RAG / AI integration work: TypeScript, JavaScript, Python, Next.js, React, Node.js, NestJS, PostgreSQL, LangChain, LangGraph, Pinecone, pgvector, n8n, OpenAI API, Claude API, WhatsApp Business API. Track record: 100% Job Success Score. As an AI Agent Developer and AI engineer, I treat AI RAG and AI integration as production engineering, not a demo — that's the standard for every AI Agent Developer engagement I take on. How I work as your AI Agent Developer / AI engineer: 1. Scope call — data, current stack, what "working" means for your AI RAG or AI integration use case 2. Technical proposal with a concrete AI engineer plan, not a generic SOW 3. Build in milestones with visibility at each step 4. Handoff with documentation, not just working code Message me with what you're building — as an AI Agent Developer, AI engineer, or AI integration partner, I'll give you a quick, honest read on feasibility before you commit to anything.
