* Primary lead for DataFed a federated metadata management application.* Technical lead for Constellation a large data repository.* Technical lead for Dataflow a data gateway application.* Designed CI and CD pipelines, for deploying and backing up Constellation on OpenShift.* Implemented CI pipelines for DataFed, including automated test infrastructure provisioning using Terraform, Ansible and OpenStack followed by complete end to end testing.* Troubleshooted problems spanning distributed services.* Created Docker compose multiservice developer environments.* Mentored three interns.* Provided technical assistance to non-technical team members.

* Addressed security vulnerabilities.* Refactored middleware of DataFed to conform to OO design principles.* Researched and evaluated different technologies to include in the software stack.* Assisted in the development and design of Zambeze a distributed workflow management application written in Python.

* Setup build configuration infrastructure and dependencies (HDF5) with Spack and shell scripts on different architectures and with differnet compiler combinations.* Assisted in developing an experimental block adaptive mesh refinement framework.* Improved code quality by leveraging open source tools, such as Codacy and Deepcode.* Built a github application capable of running performance regression tests on internal testbed systems as part of the CI pipeline.* Conducted performance benchmarking with Darshan to identifying problematic io patterns.* Regularly, participated and facilitated biweekly meetings between collaborators and internal users.* Provided code review and refactoring to clarify and improve code quality. * Created a C++ library for efficiently exploring a multidimensional state space.

* Teamed up with student to visualize and animate physics simulations using PyQt and Matlab.* Analyzed data with statistical analysis techniques to verify trends (Student t analysis, regression line fitting).* Parallelized C code with MPI for modeling exciton diffusion in disordered materials. * Initiated collaboration with VOTCA development team: participated in code review and development, added unit testing framework, unit tests, integration tests and memory checks, practiced OOP design principles and best practices.* Created a simple Hartree Fock engine in Matlab.* Generated an efficient Monte Carlo Charge Transport algorithm, in some cases improved performance by an order of magnitude.
