Message

At OceanHub Africa, I built the OceanCompass Platform from scratch, bringing enterprise assessments, financial records, programme operations, coaching, and funder reporting into a role-secured system. As the organisation’s sole software and AI developer, I also consolidated three product surfaces and reduced one LLM workflow from 48k–160k tokens to 2,375 tokens.

I built meeting and knowledge infrastructure for OceanHub Africa’s team, including permission-scoped summaries, a knowledge graph, and internal tools. My work also covered venture sourcing and programme delivery, as well as a CAD-to-results simulation platform validated against a velocity-profile error of 0.134%.

Through Studio Majiet, I support security remediation for YC-backed companies with root-cause analysis, fix guidance, and independent retesting. I also founded HealthHarmony, where I led product architecture and business modelling, and I’m completing a Master of Science in Artificial Intelligence and Machine Learning at Walsh College.
