Hi, I'm Mario

About Me

My immigrant journey: from Peru to entrepreneur

I grew up in Peru and moved to the States with my family when I was a kid in search of a better life in America.

My career has been deeply rooted in the travel and technology space, working with big companies like American Express and Microsoft.

In 2021, I launched my own web design business where I get to use my knowledge, network, and skills to help Black, Indigenous, and Brown entrepreneurs launch and optimize their websites so they can thrive.

What People Say About Working With Me

My organizations experience with Mario and his team has been simply amazing. Everything you all promised was delivered on time or ahead of schedule. GloverEmpowerMentoring-GEM 2.0 would not be complete without the excellent website design, logo rebranding, and email account creation. Finally, being provided with all the necessary tools for website maintenance and care really shows your level of commitment to your craft. Thank you.

I've had the pleasure of working with Mario for years at American Express. Mario is laser-focused on providing technical solutions to the business. He communicates well, shows understanding of issues, and works quickly to troubleshoot in a timely and professional manner. Obviously you can see how these traits translate into a powerful, productive employee, co-worker, or business partner.

Mario is an asset to any organization he joins. He is a true team player and strong client advocate. He has excellent communication skills and a quiet determination to get the job done. He is thoughtful and understands all voices need to be heard to drive an initiative to a successful completion. He successfully managed complex global technical implementations for one of the world's largest corporate travel program and understands the travel and technology space very well.

Mario is a rare blend of a creative website developer and an astute designer. His ability to translate complex concepts into user-friendly digital experiences is nothing short of remarkable. Our large project under Mario’s lead has not only met but exceeded our expectations. His designs are not just visually appealing; they are functional, intuitive, and contribute significantly to our clients' digital presence.

Mario is an extraordinary web developer and designer, and any organization would be fortunate to have him as a business partner. I wholeheartedly recommend Mario Seijo for any endeavor he chooses to pursue. He is not just a contractor; he is a vital part of Vault89’s extended family.
