I'm a Full-Stack Web Developer with over 4 years of experience crafting interactive, data-driven, and scalable web applications.
I’ve worked with global teams to deliver digital products that blend great user experience, robust architecture, and clean code — using technologies like Next.js, React, TypeScript, Firebase, Node.js, and NestJS.

• 💼 Full-Stack Developer at Skibble — Rebuilt the company’s landing page and developed a full-stack kitchen dashboard using Next.js, TypeScript & Firebase.
• ⚙️ Frontend Developer at Dantown — Led a frontend team to build internal admin systems that provided comprehensive overviews of key data, reports, and KPIs for efficient day-to-day operations.
• 🌍 Software Developer Intern at Hackernoon — Worked on interactive UIs used by 4M+ monthly users and improved API performance.
• 🧠 Developed Sedot — A full-stack pharmaceutical care platform with Next.js + Node.js, offering telemedicine consultation and online medication purchase.
• 🧑‍💻 Built EaseLab Africa — Corporate healthcare website for a startup specializing in healthcare systems.
• 🧾 Created The Diabetes Care Network — A web platform for a health tech company dedicated to helping Nigerians manage and potentially reverse Type 2 diabetes.
• 🔗 Collaborated and built NFTicket during the Base Buildathon, an NFT-based ticketing system for blockchain-powered events.
• 🎓 Earned a Chainlink Blockchain Certification and graduated Cum Laude (Distinction) from Cairo Bootcamp III, gaining hands-on experience in Cairo, StarkNet, and smart contract development.

I love solving complex problems through thoughtful design and clean code, and I aim to build products that truly make a difference.
When I’m not coding, you’ll find me watching football ⚽.
