BlinkTag Inc Logo

BlinkTag makes technology easy for city and transportation planning professionals.


We are city planners, web developers, transportation engineers, graphic artists, social media managers, and interaction designers.

BlinkTag uniquely understands the structural barriers separating communities from public resources, as well as the challenges public agencies face in reducing those barriers, because many of our technical staff are also experienced city planners.

BlinkTag is committed to reuse and libre/open source software. We strive to put publicly-funded code in the public domain.
Read more about our process.


BlinkTag adheres to the tenets of user-centered design. Successful design and strategy are informed by users’ wants and needs, rather than assumptions. To that end, before writing any code we listen to our clients. We strive to understand our audience and goals, and allow them to inform every step of the project. We then apply design research tactics, including rapid prototyping, wireframes, iterative development, and contextual inquiry to ensure that our deliverables satisfy both the audience and agency goals. We favor regular communication via check-ins and a collaborative relationship with our client thought partners.

In addition, BlinkTag supports tools that can be reused by the public. This includes both open source (meaning that others can modify and reuse it for their own purpose without cost) and free/libre (additionally, others can never charge for their derivations) licensing.


Our clients have a variety of challenges and constraints, but share a desire for data-driven solutions and meaningful community engagement.

BlinkTag was created in 2011 by people who believe that planners should be able to build their own tools. As professionals, we refused to pick planning or technology over the other, and have created a collective of experienced practitioners that embrace collaboration, consensus-making, and skill-sharing. Our clients appreciate our empathy, subject matter expertise, and context-informed approach.

Mike Vattuone, Developer

Mike has long had an interest in how the human mind interprets and interacts with technology.  A self-taught full-stack developer with a degree in cognitive science from UC Berkeley, he takes delight in synthesizing user needs and business goals into meaningful and intuitive interfaces and applications that help rather than hinder. When he isn’t playing with new technology or studying human behavior, he’s probably playing an instrument or writing a song.

At MIT, Jed’ spent his time hosting a popular radio program and writing movie reviews for its student-run newspaper (and picked up a little engineering knowledge along the way). He’s worked as a commercial real estate research analyst for Newmark Knight-Frank, studied city planning and transportation engineering as a graduate student at UC Berkeley, and now works Apple Computer. He is no longer directly involved in BlinkTag’s operations. Jed developed a taste for gambling in his native Big Easy, and tries to sneak trips to Reno whenever possible.
