Systems engineer building reliable distributed infrastructure at scale. Currently designing and operating the global loyalty platform backend for a major hospitality brand — serverless AWS services handling millions of customers across rewards programs, digital wallets, and promotional campaigns.Published research on memory management and distributed systems convergence. Proved when coarse-grained allocators produce bounded vs unbounded memory retention, and built libdrainprof, a C profiler detecting structural leaks invisible to Valgrind with <2ns overhead. Separately, proved that event-driven systems with automatic repair logic converge without coordination under normalization confluence, and built gsm, a Go library that verifies convergence at build time and reduces runtime event processing to O(1) table lookup.doi.org/10.5281/zenodo.18••••76 doi.org/10.5281/zenodo.18••••00Author of \"You Don\'t Know JSON\"(107K words).
