About

Engineering and
making things.

I'm a senior aerospace engineering student at Georgia Tech with a habit of building things that shouldn't necessarily exist yet — from custom hardware for factory floors to one-of-one keyboards for my brother.

I care about the intersection of engineering rigor and good design. Work that holds up technically and feels considered. Two co-op rotations at Delta TechOps in propulsion engineering — engine teardowns, test cell operations, and fleet-level risk systems — taught me what it means to build things that actually matter.

Outside of coursework I lead the creative and communications team at SHPE Georgia Tech, and I applied CFD methods across aerospace and biomedical domains during a research summer in Limerick, Ireland.

Currently

Experience

Where I've worked.

Delta TechOps
Aug 2024 – Dec 2024
Atlanta, GA
Propulsion Engineering Co-Op — Engine On-Wing Support
+
  • Performed PW4000 engine teardowns, borescope inspections, and system-level assessments across active fleet units, developing hands-on fluency in turbofan architecture, wear patterns, and failure signatures.
  • Built a fleet-wide risk-tracking dashboard across 40+ PW4000 engine inspection programs, embedding severity and likelihood indicators to surface high-risk units and drive preemptive maintenance decisions aligned with FAA and OEM timelines.
  • Conducted structured failure mode analysis on a critical component, analyzing 5 key failure events across 10 years of data; built a risk matrix and presented findings to engineering leadership and compliance teams.
  • Authored 7 technical documents and revised 5 maintenance procedures — identified improvements projected to reduce repair turnaround time by up to 60%.
Delta TechOps
Jan 2024 – May 2024
Atlanta, GA
Propulsion Engineering Co-Op — Test Cell Operations
+
  • Supported reliability and trend investigations across engine test cell runs, analyzing performance data against baseline parameters to identify anomalies and surface degradation signatures.
  • Designed and deployed an automated engine performance trending tool after end-to-end workflow interviews with test cell engineers — cutting time-to-insight from 30 minutes to 2, standardizing analysis across all weekly runs.
  • Led two R&D initiatives targeting off-wing test capability expansion: reverse engineered an adapter to integrate incompatible OEM hardware, and designed a fully custom portable test bench from scratch.
  • Managed first-response diagnostics during live test cell operations across 13+ weekly engine runs, coordinating cross-functional fault isolation to maintain testing continuity and safety.
GT Research
Jun 2025 – Aug 2025
Limerick, Ireland
Research Contributor — Applied CFD
+
  • Applied ANSYS Workbench and Fluent to model airflow in human arteries under plaque buildup and through engine components under varying boundary conditions.
  • Compared findings across both domains to communicate how solver and meshing choices produce materially different design conclusions.
Hytech Racing
Aug 2023 – Dec 2023
Atlanta, GA
Aerodynamics Engineer — Formula SAE
+
  • Designed and validated a nosecone vortex generator through a full development cycle from concept through real-world on-car testing, achieving an anticipated 10.1% aerodynamic performance improvement.
SHPE Georgia Tech
Aug 2023 – Present
Atlanta, GA
Public Relations Officer — Board of Directors
+
  • Elected to lead a 14-person creative and IT team for a 400+ member organization; drove 20% engagement growth in 90 days through structured outreach strategy and cross-functional execution.
  • Designed internal automation systems including a graphics request dashboard and reporting pipeline, improving delivery reliability and reducing manual coordination overhead.
