• As one of Qiskit's primary open source maintainers, shaped general technical direction, managed releases, and performed code reviews.

• Rewrote Qiskit's core data structures in Rust with highly efficient representations, reducing our compiler's memory footprint by up to 70\% for large quantum circuits.

• Designed and implemented features in support of dynamic circuits in Qiskit's transpiler.

• Led the design and development of a native WebRTC video client (C++) for a cloud-rendered in-vehicle HUD.

• Architected several big data processing solutions for prominent partner companies.

• Designed, implemented, and supported storage-related features in Azure Stack and System Center VM Manager (C\#.NET).

– Implemented indexing hints for Microsoft Azure DocumentDB using C++. This feature gives the user the ability to preconfigure storage structures with lists of specific queries that should be treated with more precision in the index. As a result, these queries are faster.

– Augmented our project’s test library to support complex parameter passing for individual tests.

– Co-lead a team to port an existing embedded system to a new Linux distribution.

– Created Bash scripts for writing the new distribution to flash media and for system initialization logic.
