About me

Hello, I am Joshua de Guzman, a software engineer with a passion for learning and teaching, based in the Philippines. A Google Developer Expert for Flutter and Dart. I work at Freelancer.com (ASX:FLN), world's largest freelancing and crowdsourcing marketplace by number of users and projects, where we connect over 43 million employers and freelancers globally.

Previously I worked at Xurpas (PSE:X), the largest publicly listed consumer technology company in Southeast Asia, where I developed Android and iOS apps as part of the company’s product line and worked with some of the country’s well-known companies.

Life outside work, I enjoy exploring and contributing to open-source projects, asking and answering questions on StackOverflow, and sharing my experiences and knowledge with the community.

In 2019, I founded Flutter Philippines where I am continuously learning how to build and grow an awesome community.

You may know me as @joshuamdeguzman on Twitter, @joshuadeguzman on Github, LinkedIn, and Keybase.
