Turning Data & AI into Production-Ready Systems That Actually Work Hi, I’m Lucas Cabral, a Senior AI & Data Engineer with 8+ years in Machine Learning and 6+ years building LLM-based systems in production. I help companies move beyond prototypes and demos by designing scalable, secure, and observable AI systems that deliver real business impact. I specialize in end-to-end AI delivery — from data pipelines and model training to deployment, monitoring, and long-term reliability. What I Do Best 🧠 Machine Learning & Predictive Analytics Regression, classification, forecasting, anomaly detection Feature engineering, data validation, model evaluation Tools: PyTorch, TensorFlow, scikit-learn, XGBoost, Spark 🤖 Generative AI & LLM Systems Chatbots, copilots, and production-grade RAG pipelines Agentic workflows with guardrails and human-in-the-loop Prompt versioning, retrieval evaluation, cost & latency control Tools: LangChain, LangGraph, LlamaIndex, OpenAI, Claude ⚙️ MLOps & LLMOps (Production Focus) Training pipelines, experiment tracking (MLflow) Real-time & batch inference via FastAPI Model/version rollouts, drift detection, observability Dockerized deployments with CI/CD ☁️ Cloud & Backend Engineering AWS (EC2, RDS, S3, Lambda), Docker, PostgreSQL Secure, scalable APIs and data services Strong focus on reliability, auditability, and cost control How I Work (Why Clients Hire Me) Production-first mindset — no throwaway demos Clear ownership: I design systems that teams can operate safely Simple > clever: boring, maintainable solutions that scale Business-aligned AI: models tied to measurable outcomes I’ve worked on AI systems across fintech, SaaS, analytics, and automation, where data quality, trust, and uptime matter. Typical Projects I Deliver RAG-based internal knowledge assistants ML-driven decision or ranking systems AI automation pipelines with approval workflows Data platforms and predictive dashboards AI MVPs that are ready to scale (not rewrite) Let’s Build Something That Lasts If you’re looking for someone who can own AI systems end to end, reduce risk, and deliver production-quality results — let’s talk. 📩 Message me to discuss your project.
