Web Developer Philippines - Janndel Mark Rosario

I develop and optimize stuff.

Who is Janndel?

Passion-Driven Developer with proven full-stack knowledge and experience in various frameworks both for Frontend and Backend Development

Hello, my name is Janndel Mark Rosario. I specialize in creating websites. Optimizing websites and making them SEO-friendly is also my expertise. I acknowledge how important my client's digital presence is so I always make sure that the projects I handle are carefully and neatly coded. Hanabishi and Megaworld Manila's websites are just some of the prominent brands I have managed and developed.

When I'm not typing codes or integrating systems, I spend my time playing video games. Or just simply thinking what video game to play next. I currently reside at Parañaque City, Philippines.

I've always seek opportunities and challenges that are meaningful for me. Before taking the Web Development Path, I was once a College Instructor in a University here in the Philippines, which I've handled and managed several courses from Computer Fundamentals, Object-Oriented Programming to Network Administration and Data Communication that help transition from teaching to development easier.

Now as a Web Developer, I enjoy using my corrective mindset in creating solutions and generating ideas. My love and dedication in coding and well-driven work ethic can help other fellow developers and expand my knowledge even more in Web Development.
