ABOUT ME


Mechanical engineer currently designing turbomachinery rotating parts for GE Aviation. Both my professional career and after hours activities orbit around technology which allows me to explore the world in a way previously reserved for only a few. Currently my focus drifts toward applying computer science to mechanical engineering as it already plays a huge role in design process but tomorrow it would be a must have.

WORK EXPERIENCE


2022 - Now

Data Analyst (Schneider Electric)

    Responsibility: ETL for Finance digital transformation.
  • Creating and updating automated pipelines on Databricks to transform Financial data based on requirements from stakeholders.
  • Translating stakeholders requirements into set of stories clear for developers to implement requested features.
  • Programming technologies: Python, Spark, SQL.
  • Using Git to update existing code in parallel to other developers.
  • Optimizing Spark code for performance improvement.
  • Exploring a data to identify and report inconsistencies or faulty logic.
  • Creating automated and data match tests for delivered Data Objects.
  • Present released product in front of the stakeholders.

2022

Staff Design Engineer (EDC / GE Aviation)

    Responsibility: Rotating parts design and technical mentoring.
  • Technical mentorship to other team members and junior staff in support of enlarging the team.
  • Participating in hiring process - interviewing candidates for employment.
  • Supporting other engine lines with QEM closures providing expertise in creep analysis.

2016 - 2022

Advanced Lead Design Engineer (EDC / GE Aviation)

    Responsibility: Rotating parts design for GE Catalyst compressor (NPI).
  • Design owner for various compressor rotor parts from conceptual stage to product introduction (FEM analysis, calcs and getting approval from CCE),
  • Working with suppliers, CCE and program leadership to work out the best solutions from program deliverables perspective to execute on time hardware delivery in support of engine test,
  • Designing module interfaces,
  • Modifying existing design based on test engines requirements allowing to lead and install required instrumentation.
  • String focus on cooperation with MFG sources to refine existing processes, inspection methods and design definition to ease the manufacturability.
  • Providing continuous on site support for manufacturing, assembly, instrumentation and engine tests.
  • Proposed improvements to design practices and became co-author of best practice for Compressor Airfoil Creep analysis
  • Created a tool which supports balancing process (automate balancing weights placement and selection),
  • Defining Engine Service Manual limits for rotating parts of compressor based on series of fracture analysis required by the design practice,
  • Created a tool which allowed to identify if high order excitation can appear as a low order forward/backward travelling wave and cause resonance with low order modes.
  • Providing continuous support to less experienced engineers and new team members.

2015 - 2016

Design Engineer (EDC / GE Aviation)

    Responsibility: Rotating parts design for CT7-2E1/2F1 compressor (NPI).
  • Coordinating efforts to execute NPI milestones.
  • All aspects of design including managing analysis resources, design reviews with CCE, working with suppliers for on time hardware delivery in support of engine test and production engine builds.
  • Creating FEM models, performing analyses, documenting results and presenting all aspects of new design in front of CCE.
  • Deep dive into bolted joint design: 2D and 3D FEM modeling for compressor rotor joint behavior under both axisymmetric and asymmetric loads.

2013 - 2015

Junior Design Engineer (EDC / GE Aviation)

    Responsibility: MFG support and rotating parts design for CT7-2E1/2F1 compressor.
  • Design owner for CT7 Impeller re-design NPI program,
  • Establishing scope, schedule and cost to meet program requirements.
  • Presenting deliverables on tech reviews, engine systems tech reviews, product control board business reviews,
  • Design calcs & 2D/3D FE analyses (static stress, burst, LCF/HCF, sub-modeling, mesh morphing),
  • Product definition & CAD modeling
  • Manufacturing support (non-conforming material dispositions (MRB) including repair authorization, hardware requirement refinements for cost reduction)
  • Engineering documentation (tech reports, component drawings, engineering parts lists, engine shop/maintenance manuals)
