Freelancer Overview

Hydraulic Measurement and Plastics Monitoring Field Assessment — Odaw River (Field Data Collector). Brings 5+ years of professional experience across complex professional workflows, research, and quality-focused execution. Core strengths include Don't disclose, PostgreSQL, and Other. Education includes Bachelor of Science, University of Energy and Natural Resources (UENR) (2022) and N/A, Adisadel College (2018). AI-training focus includes data types such as Image, Geospatial, and Tiled Imagery and labeling workflows including Land Cover Classification, Mapping, and Classification.

Labeling Experience

Trainee, Water Resources Commission of Ghana (Structured inspection reporting)

OtherDocumentClassification

Produced structured dam safety inspection reports that required category-based assessment of site conditions and compliance status. Followed standardized inspection guidelines to ensure consistent labeling of findings across multiple dam sites. Compiled compliance-oriented outputs suitable for regulatory review and post-monitoring follow-up. • Completed structured inspection reports for 23+ dams including condition and operational performance. • Ensured consistent category labeling aligned with compliance monitoring needs. • Drafted regulatory correspondence and compliance notices based on inspection outputs. • Contributed to a dam safety unit Compliance Monitoring Framework.

2025 - Present

Trainee, Water Resources Commission of Ghana (Digitisation, classification, and QA of structured records)

Mapping

Digitized, classified, and cleaned historical water-user records into a structured PostgreSQL database requiring consistent field-level accuracy and category assignment. Built automated data-cleaning workflows to enforce standardized categories across thousands of entries. Supported GIS-based spatial analyses and generation of monitoring maps that depend on consistent attribute labeling. • Digitisation of 2,700+ water-user records with classification and data cleaning. • Development of automated workflows and structured database for consistent category assignment. • GIS-based analyses including preparation of site investigation and monitoring maps. • QA focus on compliance-relevant fields and category consistency across the dataset.

2025 - Present

Volunteer — Community-Driven Freshwater Plastics Monitoring (UNEP/Wageningen University)

OtherImageClassification

Conducted structured visual counting and category-based classification of floating macroplastics along the Odaw River using UNEP/Wageningen standardized field datasheets. Applied consistent material category labels across eight defined categories while operating from fixed bridge-based observation points. Captured complete metadata fields to ensure the resulting labeled dataset could be used for international environmental research and policy reporting. • Counted and labeled floating macroplastics using the UNEP/Wageningen protocol across eight material categories. • Performed timed observation windows from fixed bridge-based sites to maintain labeling consistency. • Recorded observer details, bridge name, observation duration, and per-category item counts. • Coordinated participatory monitoring with community members to support dataset collection and reporting.

Field Data Collector — Hydraulic Measurement and Plastics Monitoring (Odaw River)

OtherImageClassification

Performed structured visual counting and category-based classification of floating macroplastics using the UNEP/Wageningen simplified categorisation protocol. Labeled items across eight predefined material categories at fixed observation points during timed windows. Completed standardized field datasheets capturing per-category counts and required metadata. • Classified floating macroplastics into eight categories (EPS, PO soft, multilayer plastics, PS, PET, PO hard, other macroplastic, other macrolitter). • Conducted counts at fixed bridge-based observation points to support consistent labeling. • Recorded observer, location identifiers, and observation duration for dataset integrity. • Produced fully completed standardized datasheets suitable for PhD-level research.

Field Data Collector — Hydraulic Measurement and Plastics Monitoring (Odaw River)

Don't disclose3D SensorData Collection

Collected structured hydraulic measurement data at bridge and weir sites to support modeling and analysis. Recorded sensor-derived measurements with required metadata to maintain data integrity for downstream research. Captured associated debris volumes and sedimentation indicators as labeled fields for flood risk modeling. • Deployed ADCP and conventional flow meters for structured hydraulic measurements. • Recorded flow velocity, channel geometry, debris volumes, and sedimentation quantities. • Completed standardized field datasheets with full metadata for QA. • Prepared labeled measurement outputs for flood risk modeling datasets.
