About Marco Henalu

Full stack web developer with a background in technical consulting and training, focused on creating modern websites, landing pages, and sites for small businesses, service brands, and personal projects.

I am particularly interested in building clear, visually appealing, and well-executed web solutions, with a focus on structure, user experience, responsive design, and technical reliability. I combine technical thinking, business acumen, and a practical approach to transform specific needs into useful, up-to-date, and maintainable web products.

I also have professional experience in integrations, automation, debugging, and delivering technical solutions in demanding environments, which allows me to approach projects with a structured, results-oriented vision.
