Mobile Apps • Web Development • Backend • AI Integrations
Samuel Ukpai (also known as Samuel Surf, Sam Surf, or Nasurf) is a Full Stack Software Developer building production mobile apps with Flutter, modern web applications with React/Next.js, and AI-powered backends deployed on Cloudflare's edge infrastructure.
From pixel-perfect Flutter mobile apps and React/Next.js web interfaces to Python backends and AI-integrated experiences on Cloudflare's edge, I design and ship full-stack products end to end.
These aren't just logos on a page, they represent real projects, real challenges solved, and real value delivered.

A clear, searchable academic portal that helped the department present the information required during its successful COREN accreditation review.
I built the College of Engineering portal to turn dense accreditation and programme records into an accessible digital experience. Department profiles, programme outcomes, course learning outcomes, curriculum mappings, handbooks, lecture plans, and supporting media are organised in one responsive interface. Dr A.O. Ojo used the portal while presenting to the COREN accreditation team, who were impressed by how quickly they could find what they needed.
AI learning platform that turns engineering course materials into quizzes, feedback, and study progress.
Engineering Hub helps engineering students study from the materials they already use. The app organizes courses by department and level, serves large PDFs through a fast Cloudflare-backed delivery layer, and uses Gemini to generate practice questions, evaluate theory answers, and give targeted feedback. I built it across Flutter, Firebase, Cloudflare, and Google Cloud with a Clean Architecture structure that keeps the learning, storage, and AI flows maintainable.
AI-Powered Productivity Coach that Aligns Your Phone Usage with Your Goals
Hawk Buddy is a goal-aligned productivity companion that helps users reclaim control over their digital habits. Unlike traditional screen-time apps that simply block or limit usage, Hawk Buddy takes an intelligent approach: it understands why you use certain apps and determines whether that usage aligns with your personal goals. The app features an AI-powered conversational coach that provides encouragement, feedback, and personalized progress summaries.
Client project for a student career conference, designed to help attendees understand the event, trust the brand, and buy tickets.
For Campus to Career 2.0, a student career conference in Nigeria, I built the public event platform end-to-end. The site gives attendees a clear picture of what the event is about, builds trust around the program, and moves them from interest to ticket purchase. It was built to drive sales.
Tools and products I have shipped alongside client work.
Website for DACTION Initiative, a youth-led environmental nonprofit in Lekki, Lagos: programs, team, gallery, and a full SEO pipeline with static prerendering, IndexNow, and JSON-LD.
Native Linux speech-to-text that transcribes audio and types into any focused app, powered by Groq and OpenRouter. Shipped as an AppImage and RPM.
Case studies, practical engineering lessons, and honest notes from taking software from an idea to production.
