Leonardo Rocha
Senior AI Engineer with 12+ years in R&D and 6+ years building and deploying production AI systems.
Specialized in Generative AI and Agentic Systems — including RAG architectures and robust evaluation frameworks.
Hands-on experience delivering cloud-native AI architectures for real-world workflow automation across on-premises and cloud environments.
Key Highlights
Led the full-cycle design and deployment of an AWS-based agentic system automating legal workflows across 10,000+ monthly cases. Ran containerized, long-running workers on Amazon EKS, consumed demand via Amazon SQS, used Amazon RDS as system-of-record, stored & searched embeddings in Amazon OpenSearch, and monitored operations with Amazon CloudWatch. Achieved >95% success rate with human validation.
Designed and implemented adaptive learning and recommendation engines using semantic embeddings and graph-based modeling, powering a national ICT training platform and improving learner engagement and completion rates.
Built a multi-agent conversational platform that simulates expert panels (CTO, PM, VC) to mentor startup founders. Agents collaborate through LangGraph orchestration and RAG-based contextual grounding, ensuring coherent, knowledge-driven dialogue. Deployed with FastAPI and Google Cloud Run for scalable interaction.
Consulted a US fintech startup on RL-based customer personalization and feasibility assessment. Participated in joint technical and strategic discussions with stakeholders from Stone and C6 Bank to define architecture options, data requirements, risk profile, and cost structure.
Developed an intelligent cybersecurity module using graph-based machine learning to detect malicious websites through relational analysis of URLs, domains, and host networks. Results were peer-reviewed and published at the 37th International Conference on Advanced Information Networking and Applications (AINA 2023).
Founded SofIA Tech, bridging state-of-the-art AI research with market applications through consulting, automation projects, and enterprise AI training. Delivered solutions using LLMs, RAG, and intelligent automation frameworks.
Founded the Graph and Computational Intelligence Lab (LAGIC) and coordinated the IncubaUECE incubator, fostering applied AI research, technology transfer, and entrepreneurship in deep-tech ventures across Ceará.
