  • Structural Engineer at RusDrevStroy
    Jun 2020 - Aug 2021 · 1 yr 3 mos

    Duties: · Designed and analysed steel frame structures in SolidWorks, including domes, frames, canopies and related steel elements. · Prepared fabrication and assembly drawings for workshop production. · Worked on the production floor on a daily basis, coordinating closely with fabricators and workshop staff throughout design and manufacturing stages. · Prepared material take-offs and calculated stock length requirements and cutting layouts for steel sections to support procurement and reduce fabrication waste. · Carried out site measurements and contributed to customer-facing technical work. Selected projects: · Internal steel structure for a church dome, approximately 4 t, 8 m diameter and 8 m high. · Self-supporting steel frame carrying approximately 2.4 t of church bells, designed to imitate a brick masonry arch after cladding and plastering. · Steel spiral staircase with decorative wrought-iron balustrade, including 3D modelling in SolidWorks and preparation of fabrication and assembly drawings. · Open steel-frame hay storage structure with snow load of approximately 57.5 t.

  • Design Engineer at Tech-Aero
    Sep 2019 - May 2020 · 9 mos

    Duties: · Created CNC plasma cutting programs for a 2-axis cutting table in SheetCam. · Prepared assembly drawings for production. · Supported workshop engineering activities. Selected projects: · Stainless-steel sluice gates, approximately 2 m high and 5 m wide. · Stainless-steel sluice gates designed for approximately 10 m water depth. Achievements: · Created a technical instruction manual for work in SheetCam. · Identified that the standard lifting screw used for typical sluice gates would be critically undersized for a new design (approximately 4 m² gate at 10 m water depth) based on basic force calculations. Raised the issue with senior engineers, which led to a complete redesign of the lifting mechanism (stronger stainless steel grade and doubled screw diameter, increasing capacity by roughly eight times) and prevented a potentially unsafe and inoperable gate.
