Senior🎓
Top SchoolHongjae Cho is a backend-focused software engineer with eight years of experience building scalable APIs and data pipelines across consumer-facing platforms. Currently at Tinder and previously at HYPERCONNECT, he has driven backend services for real-time communication and VPaaS, combining Java (Spring Boot/WebFlux) and Python (Django) expertise. His track record includes migrating legacy Python chatbot systems to Spring Boot, building SNS ad-data crawlers and automation pipelines, and integrating Redis, MySQL, RabbitMQ and AWS to improve performance and reliability. Based in Seoul, he favors pragmatic, production-ready designs and has moved between startups and high-growth products where iteration speed and system robustness matter. He maintains a public GitHub and technical blog, signaling continuous learning and an appetite for sharing engineering insights. A less obvious strength is his cross-stack fluency—he routinely bridges API, data ingestion, and automation work, making him effective at end-to-end backend ownership.
