Data processing, quality control and reporting for UAV survey projects: 2–3 projects a month at 50–200 ha, mostly topographic and shading data for photovoltaic (solar) site planning.   Led structured data processing, validation, quality control and reporting for complex technical datasets and client deliverables, through to documented sign-off. Built an automated Excel and Power Query workflow consolidating multiple CSV outputs into comparison tables, statistical summaries and dashboard-style views. P

Developed a CE marking and C0–C6 class classification implementation strategy for manufactured UAVs under EU Regulation 2019/945, documented implementation recommendations and coordinated cross-functional stakeholders across testing, procedures and implementation planning. Conducted UAV test flights on the AIR8 Medium Lifter (up to 10 kg payload) and AIR4 Rugged platforms to evaluate technical performance. Collaborated with the engineering team to assess hardware and software modifications for legal c
