Senior🎓
Top SchoolLaurent Dong is a Senior Software Engineer based in Richmond Hill, Ontario, with over 15 years of experience building enterprise applications across C/C++, C#/.NET, Java/Spring Boot and Angular, and a seven-year formal experience span in recent roles. He brings deep low-level expertise in multithreaded programming, performance tuning and RAM optimization alongside practical backend skills across SQL Server, PostgreSQL, MySQL and MongoDB. At Asigra and Proofpoint he implemented high-impact features from OAuth2 for Exchange Online backups to performance-tuned Office 365 restore components, often bridging C++/C# mixed-mode interfaces. He also contributes to open source IoT: his notable enhancements to the popular Tasmota firmware introduced expressions in rules, new time variables and memory optimizations now adopted by the project. Comfortable leading technical design and hands-on delivery, Laurent pairs a quick learning curve and adaptability with a disciplined, test-driven approach to complex systems.
