Yeyner Jesus A.

I bring over five years of end-to-end web development experience spanning frontend and backend. I've launched greenfield applications, crafting user interfaces with Angular, React, Next, Vue, Flutter, and React Native, while building secure APIs in .NET Core, Laravel, Express and Nest backed by PostgreSQL, MySQL, or MongoDB. I'm fluent in TypeScript and JavaScript, proficient in C#, and comfortable with modern UI frameworks including Tailwind CSS, styled-components, Bootstrap, and Material UI, as well as backend-as-a-service platforms such as Supabase. My work spans multiple sectors including healthcare, e-commerce, education, and communication platforms, involving complex integrations like payment gateways, real-time chat systems with WebSockets, third-party API integrations (including Twitter/X), and AWS cloud infrastructure. My work routinely involves multi-role authorization flows, secure handling of sensitive data, and close, proactive communication with stakeholders to capture requirements precisely. I'm passionate about programming, continual learning, and collaborative teamwork that delivers maintainable, well-tested solutions.
