Summary
👤
Senior🎓
Top SchoolRocky Dunlap is a System Development Engineer with 13 years of experience building high-performance developer tools and infrastructure, currently improving operational excellence for AWS CloudFormation. He designs and implements performance-focused solutions—code generators, static analyzers, profilers, and test automation—that have reduced provisioning latency spikes by 90% and cut developer toil by hours each week. Previously he led a distributed team at NCAR, architecting an esmf-profiler that helped shave 10% off national-scale weather model runtimes and managing a $3M portfolio of mission-critical projects. Rocky’s work spans deep scientific computing and cloud operations, including contributions to widely used Earth System Modeling projects like MOM6 and CIME where he implemented NUOPC integrations and restart-handling logic. He’s known for reworking algorithms and data structures for tangible speedups, advocating conceptually clean designs, and building cross-organizational technical trust. Outside of work he channels the same discipline into piano performance and ambitious home renovation projects.

Modular Ocean Model
Role in this project:Back-end Developer
Back-end DeveloperContributions:14 commits in 1 year 4 months
Contributions summary:Rocky primarily contributed to the MOM6 NUOPC cap, a Fortran module interfacing the MOM ocean model with NUOPC-based coupled systems. Their commits focused on modifying the MOM6 cap, specifically adding functionality for writing history files and incorporating updates to align with the EMC (Environmental Modeling Center) standards. The changes involve modifying the core Fortran code, particularly within the `mom_cap.F90` file, to set up scalar variables, potentially for enhanced data output and integration.
