# Serigne Saliou Lo

> AI engineer in Dakar, Senegal. AI engineering these days. Before that, satellite data for farmers and banking systems. Builds production systems end to end (backend, data pipelines, AI features, infrastructure) and keeps going one layer deeper into each domain.

Path so far: 2018 Computer science (ESP Dakar) → 2020 Registry systems (NIC Sénégal) → 2023 Banking systems (Innov4Africa) → 2024 Geospatial & data (Tolbi) → 2025 Machine learning (production) → 2026 AI engineering (now) → next Robotics → after Neuroscience → … wherever it leads

Key facts:
- 1B+: rows of model training data generated from satellite pipelines
- 10k+: farmers reached by weather-driven voice advisories
- 137×: faster on the heaviest yield endpoint, measured on 10,000 parcels
- 2.08M: parcels in a single country-scale time-series extraction
- Main author of most backend services at Tolbi (agritech, satellite data) since 2024
- Ships and runs his own SaaS products (Dawah, Yégle, Ummah, Daara and others) and an autonomous coding-agent harness (Agency)
