• Communicated in Spanish with assembly personnel to identify potential continuous improvement (CI) efforts, tooling needs, or work instruction (WI) updates, and receive feedback on prior implementations. • Designed precision tooling and fixtures in SOLIDWORKS—applying DFM/DFA & GD&T principles—uploaded drawings into IFS, and tracked fabrication via tooling request (TRs) o Successfully implemented thermocycling test fixture, resolver pancake grinding clamps, winding cheeks, and optical comparator fixture. o Supported AIM-9X tooling ramp-up by reverse-engineering legacy fixtures, modeling replacements in SOLIDWORKS, and issuing Tool Requests (TRs) for duplicate fabrication. • Led continuous improvement (CI) efforts and delivered technical presentations to the Lean Steering Committee and senior engineers o Researched replacement tube-cutting machines to improve process capability (Cpk) and reduce operator-dependent variation during motor insertion. o Conducted Root Cause Analysis (RCA) identifying oven temperature inconsistencies in the JASM cell, enabling corrective action planning. • Performed Root Cause Analysis (RCA) on Non-Conformance Reports (NCRs) to identify manufacturing or design nonconformities o Reviewed CAD drawings in IFS and provided technical dispositions for salvage, rework, or disposal of failed components. • Authored work instructions (WI) for the Oryx Additive sca1200ht and Stratasys F170 3D printing systems. o Collaborated with Oryx engineers to mitigate fume hazards from Stratasys’s NaOH-based Waterworks solution using Safety Data Sheets (SDS) and manufacturer documentation. o Streamlined additive manufacturing workflows by standardizing support removal and printer maintenance protocols.

• Modeled shroud, backface, and leakage paths in AxCent to evaluate and validate TurboLink as an integrated CFD interface o Collaborated directly with Concepts NREC engineers to debug geometry definition, leakage-path implementation, and software behavior within AxCent. o Generated structured turbomachinery meshes using NUMECA AutoGrid5, both internally via TurboLink and externally when required; collaborating with Cadence engineers to refine meshing strategies, improve grid quality, and resolve meshing-related convergence and robustness issues. o Executed steady CFD analyses in Fine/Turbo across multiple operating points to perform verification & validation (V&V) by comparing CFD results against 1D and 2D ATF GCER data, debugging geometry, meshing, solver setup, and post-processing to ensure end-to-end workflow fidelity. o Reviewed engineering drawings and Creo assemblies to tabulate compressor geometries required for AxCent input, enabling the TurboLink workflow to be emulated and validated across multiple compressor stages rather than a single configuration. • Modeled centrifugal compressor impellers excluding leakage paths to enable CFD-based extraction of Two-Zone impeller exit flow parameters within AxCent. o Leveraged TurboLink to automatically generate meshes and execute CFD analyses in Fine/Turbo. o Reproduced GCER plots and performance trends to establish CFD credibility prior to data extraction. o Developed Python script to automate post-processing in CFView to reproduce selected GCER plots and two-zone parameters based on ASME GT2024-129356. o Established a closed-loop CFD→meanline workflow, reducing reliance on rule-of-thumb Two-Zone assumptions and improving design-specific performance prediction. • Shadowed manufacturing engineers in Cold/CAM and RotorCAM to gain exposure to fabrication, assembly, and tooling processes for compressor components. • Received hands-on exposure to ANSYS MAPDL and Mechanical through compressor casing FEA training exercises

I specialized in tutoring students and guiding them through their educational journey, ensuring they are well-prepared for their next steps.

• Aided in the design of the team’s first turbopump subsystem (e-pump) by modeling impeller and volute geometries in SOLIDWORKS and developing a Google Sheet to calculate LOx, ethanol, and water impeller dimensions. • Set up and ran water flow tests on a custom pintle injector to evaluate orifice geometries and identify optimal flow characteristics. • Applied Rocket Propulsion Analysis (RPA) and MATLAB to support propulsion design and trade studies.

• Managed Bambu Lab X1C operations by creating a Google Form/Sheet system to centralize intake of part requests (.3mf files, descriptions, intended use). • Sliced files in Bambu Studio and set print parameters: infill, geometry, support type, layer height, material selection (PLA vs ASA), and plate type (PEI vs Engineering).

I discussed customers’ dietary needs and recommended what studies had shown to be the most optimal supplements for their goals. Most of the supplements I sold to people were ones I had tried myself to ensure the effectiveness of the product. I also educated people on fitness and nutrition to ensure I was giving an all-encompassing customer service.
