Hi there! My name is Tony Collen, and I'm a freelance web developer based out of Minneapolis/Saint Paul. I'm a full-stack developer, which means I'm comfortable working from the frontend, (slinging HTML, CSS and Javascript), all the way to the backend (managing databases, integrating with third-party APIs, deploying apps, managing servers).
I've been building the web for over a decade. Whether it's a more "traditional" webapp, or you're looking for something a bit more mobile, I can help transform your idea for an app into reality.
I can help train & mentor your team, observe & locate process ineffeciencies, and make recommendations to improve your day-to-day workflow. I can also recommend specific tools to improve your delivery to customers.
Location is everything. I've got tons of experience building geo-enabled mapping apps with Google Maps, PostGIS, LeafletJS, and MapBox.
Apps that exist in isolation aren't very interesting! Whether it's building a service for other apps to use, or integrating with third-party APIs, I can help get your systems talking to each other.
I was approached by SCS to design & build a custom new web application for coordinating in-home care teams.
I worked closely with a UX designer to design, develop & deliver a brand new web application for SCS according to their needs.
Tony was instrumental in helping us design, develop, and launch CareNextion.org. He coached us on various technical issues, and guided us through to launch of our first-ever software development project. We're thrilled with the end result! Deb Taylor, CEO, Senior Community Services
I worked with Immersion Data to re-architect an existing legacy application. This included planning, designing & building a brand new web application with an eye towards responsive design.
This project had a large GIS/mapping aspect to it. The back-end was built with Ruby on Rails, and the front-end was developed "single-page app" style with Backbone.js & Marionette.
Webapp & API integration. Worked closely with 3rd-party vendors to sync data between systems, and I also managed to contribute some fixes back to an open-source project as well.
Custom webapp design & development. I worked closely with a UX designer and the project owners to gather ideas & requirements, and turn it all into a working app.
Website development & custom API integration.
If you've got a project you need help with, or even just want to bounce some ideas off me, get in touch! I'm always up for a chat.
