Sean Schertell

Technical Director

I’ve been involved in web development and system administration since 1998. As an audio engineer in New York City, I began studying web design and coding as a side hobby. Since then, I’ve worked on projects for clients including MTV, Capitol Records, The U.S. Dept. of Treasury, and Dell Computers.

Having been involved in all phases of web development from command line web server administration to user interface design, I like to think I have the wide-angle perspective necessary for viewing an entire project top-down and building teams around a predetermined goal.

Jesse Hall

Technical Director

I fell in love with computers at age 16 - programming Dungeons and Dragons scenarios in Q-BASIC for Mac and recreating the Sgt. Pepper's album cover in Mac Paint. Fast forward to 2002, while still in college, I was the technical director and graphic designer of several Rockport published computer graphics and web design books.

In years that followed, I worked as a junior/senior programmer, as well as a graphic designer (winning a national award for for web design). I've deployed and managed large scale projects for companies such as AT&T, PC World, SAS, Toshiba, Costco, Intel, Adobe, and Sony. On the weekends, I play in art-punk bands and enjoy boat rides with my wife and two kids.

Erin Kodama

Project Manager

I've been a web developer and project manager for the past 5 years, managing projects from the initial stages of wireframing and design to implementation and go-live. I like to think of myself as a partner when working with clients, helping them flush out ideas, coming up with solutions, and keeping the project pushing forward.

I'm also knowledgeable in HTML, CSS, jQuery, Javascript, and have experience with PHP and MySQL. Having front end development knowledge has helped me to effectively communicate with our development team and leverage their talents and skillsets to meet our goals.

Claire Krohmer

Graphic Designer

After graduating from U.C. Davis with a B.A. in Graphic Design, I quickly got my feet wet working at a design firm for several years. After steadily working and teaching introductory graphic design part time at the local community college, I soon caught the travel bug, and spent a few months roaming around Europe, gathering inspiration and a renewed sense of passion for art and design (and craft beers, but that's another story).

I decided to take it to the next level, build up my own clientele, and explore the world of freelance graphic and web design, where I have been working for the past several years.

Evgeny Petukhov

Senior Engineer

I'm one of the master programmers behind the scenes. I'm responsible for full-stack development from the depths of automated Linux-based web server deployments to lovingly handcrafted HTML/CSS code. My job is to put it all together. I was born in Arkhangelsk, a small town to the north of Russia and I've worked for a huge number of Russian and international clients as a freelancer since high school (I still remember MS Frontpage and the HTML 3.2 era).

A few years after graduating from the local university, I moved to Bangkok, Thailand. Now I can't live/code without traveling, skyscraper views and spicy Thai food.

Michael Rosenthal

Senior Engineer

I grew up in Austin, Texas, where I frequented 24 hour coffee shops to study computer science and program -- punctuated by games of four-handed chess. Now I live life on the move, pushing code from Istanbul to Krakow. I've programmed at all levels of the software stack, doing everything from database optimization to responsive web development. I now focus this understanding intently on building both beautiful websites and beautiful code bases.

Jared Mitchell

Senior Engineer

Hi, I'm Jared. When I am not cycle touring, running, or rock climbing you will find me in front of my computer working on the latest project. My love for the outdoors is only trumped by my love for everything PHP. I built my first website in 1997, and after graduating with a BSc in Computer Science from Otago University I worked customizing e-commerce sites before leaving the comforts of New Zealand for Asia. These days you will find me in Chiang Mai, Thailand, utilizing my full stack developer skills to build customized WordPress sites. Other skills include website migration, Apache server management, and website optimization.

Cody Beardsley

Senior Engineer

I am a multi-talented individual and have experience in UI design, web development, professional game design, systems administration, project management, quality-assurance and crazy-intense debugging. I have a passion for perfection in my work and it shows in the clean and concise code I author. When there's a deadline and code quality can't be sacrificed, I'm your guy. Outside of programming, I dabble in music production, space technology and motorcycles and often create side projects involving those interests.

Azwar Khalid

Senior Engineer

I am a passionate software engineer with 10+ years of experience. My love for the web started when I created an online html tutorial forum as a high school project back in 2001. The site grew to over 1000 members, was featured on TutsPlus.com and won several online awards. Since then, I have worked on over 200 application projects serving small, medium & enterprise clients such as IBM, Motorola, GM, Rogers Communications, Remax, The Maytag Store, Royal Bank of Canada, Public Storage and Davis & Henderson.

Guillermo Salazar

Senior Engineer

Hi! My name is Guillermo and I'm the geographically southernmost asset here at DataFly. I enjoy building new services and experiences for everyone using the latest web and mobile technologies. My experience has taken me from small applications to heavily used products that serve millions and I just can't enough from it. I take a special interest in mobile applications and data flow and I love a real time chart. If you're thinking about building the next big thing. What are we waiting for?.

Konstantin Antipov

Systems Operations Specialist

Hi, I'm Konstantin. My first computer was Intel 8086 based. Since then computers have been a great part of my life and at some point they became my profession. Getting a degree in information technology at St. Petersburg Polytechnic University has structured my knowledge and improved my competence. I am currently involved in the administration of computer systems and cloud-based applications keeping myself updated with new technologies and trends.
