Flavio Fogaça

I'm a Customer Support Engineer with a background in Technical Operations, infrastructure, data investigation, and automation.

I currently work at CloudWalk, where I bridge the gap between Support and Engineering by investigating complex production issues, analyzing payment flows, troubleshooting integrations and APIs, and performing SQL-based investigations across large-scale systems. My work focuses on identifying root causes, validating data consistency, documenting findings, and helping teams resolve customer-impacting incidents efficiently.

Over the years, I have developed strong experience in technical troubleshooting, operational analysis, and process improvement. I enjoy investigating problems, connecting information across systems, and transforming complex issues into clear and actionable solutions.

More recently, I have been expanding my expertise in AI-powered workflows, automation, and agent-based systems. I actively build personal projects using Python, FastAPI, local LLMs, and prompt engineering techniques, exploring how AI can improve operational efficiency, investigations, and customer experiences.

Core areas of expertise:

• Technical Operations
• Customer Support Engineering
• SQL & Data Investigation
• API Troubleshooting & Integrations
• Root Cause Analysis
• Workflow Automation
• AI Workflows & Generative AI
• Python & FastAPI
• Infrastructure & Networking
• Technical Documentation

I'm particularly interested in opportunities involving Technical Operations, Support Engineering, AI Operations, Investigation, Automation, and AI-enabled customer experiences.
