Message

At BIGDATA GHANA, I delivered real-time yield forecasting for West African farmers by orchestrating scikit-learn models, Google Earth Engine satellite data, and AWS serverless infrastructure. I also integrated Deepgram AI to automate voice-to-text workflows, replacing manual transcription.

At SASEKLABS, I built WhatsApp PayFlow to handle payment processing, receipts, and notifications within WhatsApp. I also deployed automation workflows and automated client onboarding, cutting manual data entry by 90%.

My projects include a RAG-based assistant in ArchiveApp that grounds responses in user-specific article content, and a maize analysis pipeline combining satellite data, machine learning, and a mobile interface. I work across software development and automation using Python, TypeScript, and tools such as AWS and n8n.
