Ajayi Adeboye Samuel

I’m a Full-Stack Developer and Backend Engineer focused on building secure, scalable, real-world systems using Node.js, Express, MongoDB, PostgreSQL, and Python/Django. I approach software development with a product-driven mindset, designing systems that solve real operational problems, not just technical ones. With over a decade of experience in business management, I understand how technology supports decision-making, efficiency, and growth. This background allows me to bridge the gap between business needs and technical execution. My core expertise lies in backend architecture, including authentication and authorization, role-based access control, email verification workflows, payment integrations (Paystack), and RESTful API design. I prioritize security, clarity, and maintainability in every system I build. One of my recent projects is a Dental Clinic Appointment System backend, where I implemented secure JWT authentication, user onboarding, appointment scheduling, payment processing, and transactional email notifications. Beyond backend development, I work comfortably across the frontend with React and Next.js. This enables me to deliver complete end-to-end solutions and collaborate effectively across the stack. I’m also expanding into AI and NLP engineering, building a foundation in machine learning to support intelligent, data-driven applications in future systems.
