David Chan

CTO / Founder

David has been working as a web developer professionally since 2008. However, he first discovered his passion for software development when he got his hands on a copy of FrontPage 97 and Flash. Since then, David continues to tinker with the latest trends in software technology and acquired a vast array of valuable experience.

David followed his love for software production, visual design and programming, with several teams, before eventually leaving his role as a Senior Director to start Lumen Software where he aims to take his craft to the next level with his crew.

Masato Takeda

Full Stack Web Developer

Masato is an experienced full-stack developer. His career is peculiar - he started to work as a translator. However, as it happens quite naturally to anyone, his interest turned to simple and elegant computer languages from complex and beautiful natural languages. After teaching programming for a few years in the previous job, impressed by David's philosophy of always challenging new things, he became a member of Lumen. He is pursuing the complete code that makes full use of the characteristics of the language, and loves the framework that can realize it.

Currently Typescript and Angular are his favorites.

Maral Mosayebi

Full Stack Web Developer

Maral started working as a software developer with C++ language back in 2007, working mainly on low level programming for ATM and point of services devices. However, after a while, she developed a passion for Web development and started as a front - end developer in 2013. After touching Nodejs more, she is now an enthusiastic developer in her own right.
She strongly believes that a good programmer needs to be continually expanding his / her knowledge base while searching for innovative and creative solutions that exceed client needs.

She loves to learn and always accepts challenges.

C├ęcile Habran

Design Generalist

Cecile is a swiss-knife (or should we say a belgian-knife), juggling with various skills, from front-end development to illustration, including design.

Cecile studied illustration for three years then chose to learn web design and development for three more years. Since, she's always trying to use them both in the same projects, with the idea that they're great partners in UI and help user having a great experience.

George Grafos

George is fresh out of university and ready to leave his mark on the industry. He completed a Computer Science program in college in order to pursue a career in video game development. However, he turned his gaze towards web development after taking a class in school. George has taken part in several hackathons, and even won one too!
