How to Design an Event-Driven Analytics Pipeline — A System Design Deep Dive

Senior Backend Engineer with 11+ years building distributed systems in fintech and payments — across PayPal, Goldman Sachs, Amazon, and early-stage startups. My work has spanned real-time payment infrastructure (PIX Brazil), crypto wallet platforms, large-scale monitoring automation that cut MTTR by 78%, and event-driven analytics pipelines. I gravitate toward problems where correctness and scale are both non-negotiable — the kind of problems that break naive designs quickly. Outside of engineering, I mentor backend engineers on system design, interview strategy, and career navigation. I run a mentoring practice on Topmate (Top 1%, People's Choice) and believe the best investment you can make early in your career is learning to communicate your thinking as clearly as you execute it. I write about distributed systems, fintech engineering patterns, and what senior-level interviews actually test — drawing from real systems I've built and real mistakes I've made.
