# Dani Ezzeddine > Software Engineer Location: San Francisco, California, United States Profile: https://flows.cv/daniezzeddine Full stack software engineer with over 5 years of experience building and scaling distributed systems in fast-paced startups. Throughout my career, I've worked mostly on the fullstack with more focus on backend - Python, Golang, PostgreSQL, MongoDB, ClickHouse, Redis, Apache Kafka, React, and TypeScript. I developed expertise in building products from concept to scale, working closely with cross-functional teams to deliver features that drive growth throughout my journey in three innovative startups. My current role involves building distributed systems that process millions of requests and terabytes of data daily, performance optimization, data pipeline design, and system reliability. I've successfully implemented real-time data processing solutions, optimized database architectures, and built highly available microservices aimed to maintain uptime under heavy loads.
