I served as a drone pilot to capture high-resolution aerial imagery over large areas, notably for the demarcation of a 1,000-hectare mining quarry, while adhering to aviation safety protocols and precise georeferencing standards.

I processed the collected digital data (photogrammetry and lightweight LiDAR) to produce high-precision deliverables: orthophotos, digital elevation models (DEMs), digital surface models (DSMs), and spaced contour lines.

I oversaw the quality validation of the 3D models and final plans, ensuring compliance with topographic standards and client requirements.

I maintained regular communication via WhatsApp calls with the French client to review progress, adjust priorities, and present interim results.

This experience enabled me to effectively manage complex topographic projects in a mining environment, master the workflow from drone data collection to photogrammetric processing to certified deliverables, and deliver reliable orthophotos, DTMs, DSMs, and reliable contour lines that served as the basis for the quarry’s planning and legal demarcation.

Digitization Project Manager

February 2024–December 2025 • BIGTOPO • Madagascar

I served as a project manager at a land surveying firm, where I led a competitive project to digitize cadastral documents and critical geographic maps.

I coordinated the technical teams (data entry operators, GIS technicians, quality control specialists) and managed resource allocation (high-resolution scanners, workstations, georeferencing software) to ensure a smooth workflow and adherence to deadlines.

I oversaw the entire digitization process: scanning paper documents, image cleanup, precise georeferencing, partial or complete vectorization, and integration into an accessible geographic information system.

I ensured strict adherence to defined templates and quality standards (geometric accuracy, cadastral nomenclature, attribute integrity, and traceability of changes) by implementing cross-checks at each stage to prevent any loss or alteration of sensitive data.

I managed bottlenecks (damaged documents, cadastral inconsistencies) by making decisions and adjusting priorities to keep the project on schedule. I led the final validation process, ensuring a perfect match between each digitized map and its associated cadastral title block, making the data reliable and immediately usable.

This experience allowed me to demonstrate a proven ability to lead a sensitive heritage digitization project, delivering fully reliable, accessible, and compliant digital archives that enhanced the quality of cadastral services and facilitated subsequent processing.

3D Image and Satellite Data Processing Manager

March 2023–December 2023 • Business Process Outsourcing (BPO) Company – Madagascar • Madagascar

Clients: French companies

As part of a mapping project in France, in my role as Manager of 3D Image and Satellite Data Processing, I contributed to the production of detailed geographic information for infrastructure projects. I processed point clouds from laser scans (aerial and ground-based LiDAR) to generate accurate 3D models, performing data cleaning, classification (soil, vegetation, buildings, infrastructure), noise reduction, and the creation of mesh surfaces.

I was responsible for the complete creation of the final cartographic maps from these point clouds, integrating high-resolution satellite data to enrich the thematic layers (roads, utility networks, land rights). I strictly adhered to the required DWT template, applying the rules for symbology, nomenclature, geometric accuracy, and attribute structuring to ensure consistency and a level of quality suitable for use by engineers and urban planners.

I produced compliant cartographic deliverables (vector maps, orthophotos, digital elevation models) and prepared the associated technical progress reports.

I participated in regular video conferences with colleagues based in France to present progress, validate technical decisions, and adjust priorities based on feedback.

This experience allowed me to master the complete 3D and satellite data processing workflow within a demanding, standardized context, delivering reliable, high-precision geographic information that served as a solid foundation for infrastructure studies and mapping projects.

Field Topographic Data Operator

February 2022–February 2023 • Business Process Outsourcing (BPO) Company – Madagascar

I worked as a data operator at a land surveyor’s firm, responsible for processing and managing topographic data collected for the Talatavolonondry highway project—as part of a large-scale land administration program.

I received, cleaned, and structured data from field surveys (GNSS, total stations, drones), performing georeferencing, point classification, surface creation, and the generation of site plans in accordance with required standards.

I integrated existing cadastral and land data to produce accurate right-of-way maps, identify affected parcels, and calculate the areas impacted by the highway’s alignment.

I strictly adhered to the templates and quality standards defined for site plans, ensuring geometric consistency, rigorous cadastral nomenclature, and complete traceability of the processing performed.

I prepared and presented technical progress reports during regular videoconferences with colleagues based in Egypt, outlining progress, identified discrepancies, and proposed adjustments.

This experience allowed me to contribute effectively to the preparatory phase of a major infrastructure project by delivering reliable and actionable topographic data for land valuation and expropriation, despite the project’s subsequent suspension due to external funding issues.

Validation and Quality Control Manager

February 2020–August 2022 • Atsimondrano Topographic District • Madagascar
