- Resolved AOG-level mechanical defects by coordinating engineering, production, and airline stakeholders to deliver airworthy, cost-effective in-service fixes - Authored Anomaly Reports, Design Change Proposals, and Service Bulletins per EASA Part 21G and Part 145 - Primary coordination point across engineering, production, airworthiness, and test departments for customer case closure - Managed production and maintenance activities using ERP systems in compliance with aviation regulations

- Characterized a hypersonic wind tunnel (Ludwieg Tube) for scientific - Conducted over 120 wind tunnel test runs, gaining deep understanding of experimental aerothermodynamics - Data analysis of high-speed aerothermodynamic measurement (shockwave, heat flux, pitot pressure) relevant to UAV and reentry vehicles - Extended steady test time by 30% through research-driven aerodynamic shaping of a supersonic diffuser, validated with pressure tap instrumentation and Python-based data reduction

- Designed and manufactured a custom high-precision pressure sensor rake tailored to wind tunnel characteristic. - Calibrated sensors, integrated electronics, and selected measurement instruments along with respective Software. - Organized the Bill of Materials (BOM) for test models, ensuring manufacturability, quality compliance, and procurement efficiency - Documented test reports and the safety user manual of wind tunnel with 20MPa and 900K storage tank capacity

- Integrated, calibrated sensors and executed pressure, wind velocity measurement in Göttingen-style low-speed wind tunnel - Optimized costs in boundary layer investigations by redesigning sensor materials and built components
