I build intelligent, human-centered products.

I'm Marvelous Eromonsele, a First Class Computer Science graduate from the University of Hertfordshire and a Full-Stack & AI Engineer who builds real, deployed digital products rather than just prototypes. I specialise in scalable web and mobile applications using Next.js, React Native (Expo), and NestJS, combined with applied AI systems powered by OpenAI and Anthropic.

I've been developing at Eroslab since 2024 and have since independently shipped four live products. FocusMateApp is an AI-powered productivity platform built as my final-year project, with real-time focus rooms and personalised AI coaching. BandCheck AI processes real UK government property data to help homeowners identify council tax overpayments, addressing a problem affecting an estimated 400,000+ UK households. FoodSave Local connects businesses with local charities to redistribute surplus food in real time, and was selected as a finalist for the Best Positive Impact Award at the University of Hertfordshire's Flare Enterprise Awards 2026. HertsMarketplace is a campus-focused buying and selling platform enabling students to trade securely.

I'm drawn to problems where getting the data right actually matters, where "looks correct" and "is reliable" are genuinely different bars, and I hold myself to the second one. I'm passionate about building technology that creates measurable, real-world impact rather than just technical novelty.
