What I'm looking for

I want a role where I can drive performance and reliability in complex systems, improve throughput without sacrificing correctness, and build automation that shortens debug cycles—collaborating closely with cross-functional teams to ship high-quality outcomes.

I’m a VMware R&D Engineer focused on building high-throughput, dependable software for data backup/recovery and virtualization environments. I’ve led performance upgrades and delivered large-scale stability improvements through deep log analysis and disciplined engineering.

At VMware, I reconstructed single-threaded synchronous data writing into a multi-threaded concurrent architecture—maintaining the bottom line of data consistency while increasing write throughput from 500MB/s to 1700MB/s. I also rebuilt the customer behavior recording module to resolve vCenter upgrade compatibility issues, restoring functionality quickly with cross-version support.

Earlier, I developed core autonomous driving capabilities, including multi-sensor data fusion perception (roads, obstacles, surrounding vehicles, drivable boundaries) and trajectory prediction in high-speed scenarios. I applied the Bang Bang algorithm for horizontal motion and DFS/A* for vertical path planning, producing accurate intention-aware trajectory outputs.

I’ve also built distributed, high-concurrency video systems using ZooKeeper, created automated testing frameworks with OpenStack and REST API, and implemented CI/CD automated testing platforms to speed up defect localization. Across domains, I bring exceptional adaptability and a proven track record of rapid skill acquisition, strengthened by efficient communication and strong teamwork.

VMware R&D Engineer

Vmware

Jun 2021 - Apr 2026 (4 years 10 months)

Led a performance upgrade for data writing by redesigning synchronous single-threaded writes into multi-threaded concurrent writing, increasing throughput from 500MB/s to 1700MB/s while preserving data consistency. Rebuilt a customer behavior recording module for vCenter upgrade compatibility and implemented a disk-path local caching scheme to eliminate repeated ESXi-to-disk lookups.
