Summary
👤
Senior🎓
Top SchoolAlexey Lapshin is a Senior Software Engineer with a decade of hands-on experience building embedded systems for telecommunications, specializing in EPON/GPON access and complex L2/L3 traffic datapaths. He blends low-level C/C++ networking expertise with multithreaded optimization and pragmatic debugging skills, having designed datapath components for optical line terminals and aggregation nodes. At Espressif he contributed to the widely used esp-idf framework—adding FreeRTOS debugger integration, backtraces for memory faults and hardware stack guards—demonstrating a focus on reliability and developer tooling. Alexey’s open-source fixes to packet-processing libraries show attention to protocol edge cases (e.g., VLAN ID handling) and portable endian correctness. Based in Chiang Mai, he pairs telecom domain depth with embedded IoT craftsmanship and a security engineering background from NSTU.
