Key Contributions

• High-Concurrency Engineering — Architected and optimized backend services to ingest real-time data from thousands of GPS and telematics devices via TCP/UDP socket servers, focusing on low-latency processing and data integrity.
• Protocol Engineering — Developed custom telemetry protocol parsers in .NET, supporting complex binary, hexadecimal, and ASCII formats with extensible decoding logic for multi-vendor hardware compatibility.
• Simulation & Tooling — Built Python-based diagnostic tools to emulate device communication, allowing injection of test payloads and validation of end-to-end message flows under heavy load.
• Technical Forensics — Utilized SSH tunneling and traffic redirection to capture raw data streams, performing deep log analysis and protocol reverse-engineering to debug hardware-to-cloud communication issues.
• System Reliability — Improved platform stability with robust error-handling and diagnostic logging for edge-case device behaviors in the field.
