Senior🎓
Top SchoolDejian X is a Staff Software Developer with 13 years of experience building scalable search, backend and data systems for large consumer and enterprise products. He has led teams and processes while architecting high-throughput search engines and SaaS platforms, from C/C++ indexing for 100M+ documents to Golang microservices, gRPC APIs, MySQL/Redis schemas and ElasticSearch-based search modules. His work spans web, mobile and embedded dealer systems—shipping crawl pipelines that processed hundreds of thousands of cars, dealers and images and a software distribution service used by 3000+ dealerships. Now at Fortinet, he brings proven operational rigor in CI, testing and agile workflows alongside hands-on design and implementation. With an MS in Cybersecurity and a BS in Information Engineering, he blends system-level performance engineering with security-minded architecture. A detail that often goes unnoticed: he has deep, end-to-end experience from low-level search engine internals to customer-facing marketing features, making him comfortable across the full product lifecycle.
