Get To Know Me Better
I’m Segun Jr Agbetuyi, a full-stack engineer with a little over 5 years of experience building web products and AI-powered features. I enjoy working on things end-to-end, from shaping an idea to writing the code, to shipping and improving it based on real user feedback. Over the years, I’ve worked across frontend, backend, and cloud infrastructure, and I’m especially comfortable with JavaScript/TypeScript, React/Next.js, Node.js, and Python. I also hold an AWS Developer Associate certification and enjoy setting up solid CI/CD pipelines that make teams faster and more confident shipping changes.
I care a lot about writing clean, readable code and keeping things simple where possible. I like collaborating closely with designers and product teams, helping turn fuzzy requirements into practical solutions. Outside of work, I enjoy building side projects (often experimenting with AI integrations), contributing to open source when I can, and helping other developers grow. I’m always curious, always learning, and I genuinely enjoy building things that people find useful.
