About

I’m a systems-focused Software Engineer who builds resilient, high-performance, cloud-native systems. My engineering identity sits at the intersection of distributed systems, backend engineering, and large-scale reliability. Across Walmart, NCR, IQIT, and Geophysical Tech, I’ve delivered: -> Cloud-native systems running across 4,600+ clusters -> Kernel-level performance optimization for high-throughput workloads -> Transaction-critical microservices for retail & financial systems -> Progressive delivery and autonomous rollbacks at scale My expertise spans Java, C++, distributed systems, Kubernetes, performance engineering, and cloud platforms, supported by certifications in CKAD and AWS SA Associate. My engineering philosophy: Build for scale. Measure everything. Automate what breaks. Deliver reliably.

Senior Software Engineer

Sep 2024 – Dec 2024 · 3 mos · Houston, Texas, United States · Hybrid

Architected a high-throughput, multithreaded data acquisition pipeline in C and Java, interfacing directly with low-level kernel drivers on resource-constrained Linux SBCs to ensure nanosecond-precision data integrity from seismic sensors to storage.
Profiled and diagnosed system-wide performance bottlenecks at the hardware level, resolving USB controller contention, tuning kernel network stacks, and optimizing interrupt handling (IRQ) to increase data capture reliability by >99.9% in harsh field environments.
Engineered a polyglot IPC bridge (C, Java, .NET) using shared memory and message queues for high-speed, low-latency communication between real-time data collectors and user-facing analysis applications, collaborating with data science teams to set interchange standards.
