About

Mechanical Engineering PhD candidate with experience in mechanical design support, CAD modelling, finite element analysis, materials research, experimental testing, and technical documentation. My background combines research and applied engineering work in nanofiber materials, polymer systems, mechanical characterization, prototype support, and simulation-based problem solving. Skilled in SolidWorks, AutoCAD, ANSYS Workbench, and ANSYS APDL. I can support clients in CAD modelling, engineering drawings, research-based technical work, simulation support, materials-related projects, report writing, and product development documentation.

Experience

Research Assistant Riga Technical University · Full-time Oct 2021 – Aug 2025 3 yrs 10 mos Riga, Latvia 1. Conducted research and development on polymer and nanofiber systems, including PA6/PVA core-shell nanofibers, PA6 hollow nanofibers, PAN nanofibers, and nanofiber-reinforced composites.
2. Planned and performed experimental work involving polymer solution preparation, coaxial electrospinning, nanofiber mat fabrication, annealing, thickness measurement, and sample preparation.
3. Performed tensile testing and mechanical characterization of nanofiber mats, polymer composite laminates, epoxy/nanofiber composites, and composite rope materials.
4. Generated and analyzed force-displacement and stress-strain curves; calculated tensile strength, elongation at break, Young’s modulus, mean values, and standard deviations.
5. Processed experimental data in Excel and prepared graphs, tables, technical summaries, reports, and presentation materials.
6. Conducted SEM/TEM-based morphology analysis to study fiber diameter, hollow structure, lumen formation, shell geometry, and structural defects.
7. Developed analytical and FEM-based interpretations for hollow-fiber geometry, stability, and structure-property relationships.
8. Created ANSYS Workbench and APDL models for fibers, composite laminates, representative fibrous networks, and hollow tube cross-sections.
9. Supported CAD and prototype-related engineering work using SolidWorks and AutoCAD, including 3D modelling, orthographic drawings, and technical documentation.
10. Contributed to a military medical backpack design project through CAD-based concept support, prototype documentation, and engineering recommendations.
11. Assisted composite rope research by preparing samples, supporting tensile testing, and contributing to technical abstracts and conference activities.
12. Prepared scientific manuscripts, conference abstracts, posters, PowerPoint presentations, thesis documents, and publication-quality figures.
13. Supported teaching activities for bachelor’s and master’s courses, including practical sessions, consultations, exam assistance, and assignment evaluation.
14. Collaborated with international research partners, including TalTech in Estonia and Rouen University in France, for characterization and professional development activities.
