Jamie Toolin
Independent technology consulting from São Paulo, Brazil — software architecture, mobile apps, and product-minded solutions engineering, with a long focus on public transit.
JT Consultoria em Tecnologia da Informação Ltda is the consulting practice of Jamie Toolin. I help teams understand hard problems and apply practical technology to solve them — from architecture and advisory work to shipping real systems and apps.
Services
Engagements range from short advisory work to long-term architecture and delivery. Four threads run through all of it:
-
Solutions & software architecture
System design, integration, and technical decision-making for complex products — understanding the problem space deeply before committing to the how.
-
Mobile apps for Apple platforms
Hands-on native development experience since the first year of the App Store — from SDKs used by other developers to consumer apps.
-
Product & technical advisory
A product manager’s read on user behaviour combined with an engineer’s grasp of feasibility — help deciding what to build and why, not just how.
-
Public transit technology
Fare systems, passenger information, and real-time data — most of my career has been spent applying technology to public transport.
About
Jamie Toolin is a technologist and solutions architect whose career has run alongside the App Store since its first year — starting with a real-time bus app for Edinburgh in 2008. Since then he has moved from hands-on iOS development, through leading mobile teams and building SDKs used by other developers, to shaping architecture and advising on product and technology decisions — most of it applied to public transport.
JT Consultoria em Tecnologia da Informação Ltda is the legal entity through which this work is carried out — consulting engagements and the company’s own apps. The company is registered in São Paulo, Brazil, and jamietoolin.com is its website.
Apps
Alongside consulting, JT Consultoria develops and publishes its own apps for Apple platforms. The first apps are currently in development and will be listed on the apps page when they ship.
