Hi, I’m Jeremiah Okoroma, a product-focused data analyst and engineer with a foundation in petroleum engineering. I blend analytical rigor with hands-on software development to turn ideas into value-driven products. I founded Neritic Labs and launched MantaForge, an AI-powered fitness and nutrition app live on the Apple App Store and Google Play Store with paying subscribers in multiple countries. Originally trained in reservoir geoscience and petroleum engineering, I bring advanced skills in technical modelling, problem-solving, and systematic analysis to software development. I’m proficient in SQL, Excel, Power BI, Tableau, Flutter, and Firebase, and I’ve driven projects end-to-end from concept through deployment, app store submission, subscription management, and user acquisition.
