About me

Portrait of José Miguel Calvente

I'm a Full Stack Developer based in Barcelona, specializing in innovative digital solutions. With years of experience across international projects, I add value to multidisciplinary teams and build robust, scalable applications.

My core expertise is .NET Core backend development with C#, building efficient, secure and high-performance services. On the frontend I work with React.js to create dynamic, highly interactive user interfaces.

If you're looking for a dedicated engineer who ships high-quality technical solutions, I'd be glad to help bring your ideas to the next level.
