The Boeing Company

Design Engineer, High Lift Systems April 2020 ~ July 2020

• Supported the design, manufacturing, and service of flight control and high lift control systems and components

• Mitigated production issues by responding to corrective action reports

• Investigated and proposed cost down ideas to leadership for 777-X high lift systems

• Acted as design authority for drawing update requests

• Performed tolerance analysis & stack-up within the 787 leading edge slat actuator which resulted in a design change The Boeing Company

Design Engineer, Primary Flight Controls January 2019 ~ March 2020

• Project lead for a new primary flight controls solenoid operated valve (SOV) specification control document (SCD) o Derived hydraulic and electrical requirements to ensure procured unit worked on all intended higher level assemblies

o Led requirement review board meetings with team to approve proposed SCD requirements within the engineering requirements repository (IBM Rational DOORs) o Devised a test plan for testing existing solenoid valves to develop a baseline of requirements o Drafted envelope drawing and authored specification control document defining performance requirements o Solicited supplier proposals by creating an RFP package in collaboration with supply chain

• Supported the 787 flaperon actuator re-design

o Utilized a range of lab equipment including but not limited to CMM and CT scans to gather dimensions and performance data to be used as base-line for new actuation components design o Utilized CATIA V5/Enovia to create as-built CAD models of components and develop a top level layout drawing for manufacturing cost evaluation

o Developed a BOM and part numbering scheme

o Supported development of the kinematic model and stiffness calculations

• Project lead for the 787 flaperon hold down check valve re-design o Developed dynamic analysis model using Easy5 to simulate valve performance to validate design requirements under simulated hydraulic scenarios

o Performed static analysis using MATHCAD for verification to design requirements o Supported a common valve design effort and reduced monthly overall production cost by 50%

$18,000/month $9,000/month from material procurement to final ATP testin

• Participated in a work rotation program at Boeing’s Portland, Oregon site o Gained an understanding in the design for manufacturing (DFM) techniques by shadowing manufacturing, liaison and quality engineers

o Introduced to various machines and manufacturing processes and created mock routers for hydraulic actuator components

o Witnessed the MRB process on shop floor and gained knowledge in managing non-conforming parts Tur-bo Jet Products Co. Inc.

Manufacturing Engineer January 2018 ~ December 2018

• Developed work instructions for production shop floor

• Collaborated with production, accounting, program management, quality, and final test lab

• Improved manufacturing method and cost by designing press tooling which allowed in-house manufacturing of metal washers vs. purchasing from an outside vendor

• Provided support for root cause and corrective actions assigned internally and externally from customers

• Participated in MRB activities by dispositioning parts for re-work, return-to-vendor, scrap, or use-as-is

• Reviewed engineering change requests (ECRs); verified and recorded disposition through change summary notices

(CSNs)

• Prototyped and designed a pressure test manifold to fulfill customer’s drawing requirement of testing braze joint integrity @1500psi using a mil-spec oil

• Specialized in solenoid valves, relief valves, and coils Tur-bo Jet Products Co. Inc.

Quality Engineer June 2016 ~ January 2018

• Assisted in customer quality support

• Direct hands-on inspection of parts

• Collaborated with customer service, purchasing, production, engineering, shipping, and final inspection

• Created FAIRs (First Article Inspection Reports) in accordance to AS9102

• Presented FAIRs and product during customer source inspection

• Participated as a Honeywell Self-Release Representative (SRR)

• Generated inspection plans for final and in-process inspection utilizing Inspection Xpert software

• Devised final product material and process certification packages for customers

• Assisted initiating ICARs (Internal Corrective Action Report)

• Performed internal audits to AS9100/ISO9001 and construct audit reports

• Participated in MRB as quality representative

• Reviewed customer contracts and flowed down quality requirements into MRP system Education
