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.

Top Rated · 100% Job Success · 26 jobs, every single review 5 stars. I build AI agents and LLM automations that run in production: agentic workflows that classify, act, and notify, RAG systems grounded in your data, web scraping pipelines, and the Python backends that power them (FastAPI, LangChain, Docker). What clients hired me for recently (all 5.0): • Autonomous AI outreach agent — "All was perfect!" • YouTube analysis pipeline (transcription → LLM → Notion CRM), delivered in 4 days — "quickly and with all the requested details" • Audit and improvement of a custom AI system on a VPS — "professional, responsive... communicated clearly" • E-commerce web scraping (Python, BeautifulSoup, Playwright) • API integrations — "I've rehired Ben several times" What I can build for you: • RAG systems / chat-with-your-data: LangChain, ChromaDB, vector search over your docs, FAQs and reports. Built a RAG chatbot for an administrative firm that cut document search time by 60%. • AI agents and automation: scraping → decision logic → API actions. OpenAI, Claude, local LLMs. • Chatbots and assistants: built an admin support chatbot for a logistics company that reduced response time by 40%. • AI-powered OCR: fine-tuned Microsoft TrOCR on 10,000+ samples for handwritten math recognition, 98% accuracy, PDF and image to LaTeX. Saved a university research team 15+ hours per week. • Web scraping and data extraction: Playwright, Selenium, Scrapy, BeautifulSoup. Secured sites, anti-bot handling, 1,000+ records per month pipelines, clean structured output. • Python backends: FastAPI, Django REST, PostgreSQL, MongoDB, Stripe payments, Redis/Celery background jobs, Dockerized deployment. Why clients come back: • Day job since 2023: AI engineer shipping production systems at a software company. Your project gets production standards, not prototype shortcuts. • No black boxes: clean code, documentation, and a handover your team can maintain without me. • Fast communication (0-4h average response), fluent English and French.
