Rockstar🎓
Top SchoolJianbo He is a Senior Software Engineer with over a decade of experience building scalable back-end systems and mobile clients, recently augmented by an MSc in Computer Vision from Queen Mary University of London. He is proficient in Python, Java, Kotlin and PyTorch, and has a strong track record of designing and deploying performant services in agile, cross-team environments at companies like ByteDance and Xiaomi. Jianbo is an active open-source contributor to the EMQX ecosystem—improving MQTT clients, brokers, benchmarks, and docs—where his work on protocol handling, API clients and performance fixes boosted reliability and flexibility for IoT deployments. He blends systems-level thinking with data-driven optimization, often focusing on test automation and API design to reduce production risk. Comfortable switching between mobile, backend and ML/vision domains, he brings a practical eye for refactoring and observability that keeps long-lived systems maintainable. Off-hours he’s as likely to be found exploring virtual worlds as he is debugging a distributed system—evident from his playful GitHub bio referencing Dwarf Fortress.
