Interested to offer me an opportunity? Want me to be your speaker? Care for a coffee talk? Send me an email at or visit my links below! If you want me as your developer, I can offer end-to-end consultation, advising, and/or implementation from client all the way to back-end.


I’m Kristian Guevara, a tech-savvy, full-stack developer, visionary, traveler, and an out-of-the-box person. Pretty much it I guess (but not really… lol what)? I love brainstorming, engaging on thought-provocative sessions, watching documentaries, reading books, writing code, solving problems, creating things, and changing the world with my passion. I’m currently the co-founder of Stack. Its grassroots are all from passion and I’ve been living the startup dream for years.

I’m also a co-founder of a non-profit movement that aims the youth to think outside of the box in order to change the world! Gave up a lot of opportunities to pursue my dreams and so far, all are worth it. Made a lot of risks yet the fun never stops as challenges go through along the way. I love giving talks to people about technopreneurship and motivation as it’s a way for me to express myself and contribute my knowledge to society. I blog whenever I have time as my laptop serves as my best friend. Most of what I post are based on my experiences.

I’m also a huge geek. Talk to me anything about Star Wars, Marvel, Kingdom Hearts, fan theories, or anything under the sun! As long as it’s interesting and educating!
