TOP RATED | 100% Job Success | 5+ Years in AI & Automation & Data analysis If you need an AI solution that actually ships and works in production — not just a proof of concept — you're in the right place. I specialize in building AI agents, intelligent automation pipelines, and data-driven systems using the latest tools: GPT-5, LangChain, LlamaIndex, OpenAI Codex, and Make. Whether you need a fully autonomous AI agent, a smart scraping pipeline, or a machine learning model deployed into your workflow, I handle it end to end. What I work on: AI Agents & multi-agent systems (LangChain, LlamaIndex, GPT-5) Workflow automation (Make, n8n, API integrations) Web scraping & data extraction at scale ML model building, training, and deployment Data analysis, dashboards, and visualization (Python, Power BI, SQL) Results I've delivered for clients: Automated a client's entire lead qualification process using a GPT-5 agent — cutting manual work by over 20 hours a week. Built a LlamaIndex-powered document assistant for a legal firm that searched 10,000+ files in seconds. Developed and deployed predictive ML models for e-commerce and finance clients with measurable accuracy improvements. I hold an engineering degree in Data Science and AI, and I've maintained a 100% Job Success Score across every engagement. I don't disappear after delivery — I make sure it works for your specific use case. If that sounds like what you need, send me a message and let's talk through your project.

I build production-ready LLM systems and agentic AI pipelines that automate complex workflows. Top Rated on Upwork | 20+ projects in multi-agent AI, generative models & data engineering with PyTorch. Clients come to me when they need AI systems that actually ship — not prototypes. Whether it's a multi-agent orchestration layer, a custom RAG pipeline, a diffusion model for audio/image generation, or a data engineering workflow at scale, I handle the full cycle from architecture to deployment. What I work on: → Agentic AI & Multi-Agent Systems (LangChain, LangGraph, Groq, tool-use agents) → LLM Integration & RAG (retrieval pipelines, fine-tuning, prompt engineering) → Generative AI — Audio & Image (diffusion models, voice synthesis, latent space modeling) → ML Model Development (PyTorch, TensorFlow, classification, NLP, CV) → Data Engineering & Pipelines (PySpark, AWS SageMaker, ETL, 100GB+ datasets) Recent work includes a 7-layer multi-agent data processing engine, a latent diffusion model for synthetic medical audio generation (reduced FAD from 18.82 → 14.71), and a natural language chatbot interface for Grafana dashboards. I communicate clearly, deliver on time, and document everything. I don't disappear mid-project and I don't overpromise scope. If something's not feasible, I'll tell you upfront. If you're building something serious in AI — let's talk. Send me a message and I'll usually reply within a few hours.
