    Hi there - thanks for considering me for a job. I've been a software entrepreneur three times and those experiences taught me how to transform a product from the early idea stage to an app with 5 star ratings. I can help you with multiple aspects of your project from considering the business case, to assisting with UX design, creating the UI assets, and developing the app. I’ve built for both front-end and back-end, and I can set up servers to support apps with data, user management, background tasks, push notifications, text messages, cheap email campaigns, etc. You can check out my latest app at Technically speaking, I have excellent knowledge of iOS and Python/Django, plus decent exposure to a broad set of supporting tools (+ a willingness to learn). Here’s a little more about me: I’m the oldest of five Californian kids. I’m based in San Francisco and have been in the Bay Area most of my life, though I spent some very formative years in LA as well. I love to travel and I’ve been to 74 countries, including spending some time living abroad. Maybe you can tell me where to go next! I have experience creating both iPhone applications and REST APIs from scratch to completion. In addition, I have over 6 years work experience as a part of senior management in start-up companies and as a strategy consultant. My weakness is that I have not built an Android app, though if your requirements are simple enough, I will learn how. I’d be happy to meet with you and your team, and to work together on creating an amazing product. I have a passion for building and improving, so I bring a lot of enthusiasm and energy to my work. Looking forward to talking to you. ~ Bryan Areas of Expertise: Objective-C (iOS iPhone and iPad development) ,Python/Django Framework, Redis, Celery, RestKit, JSON/XML, GitHub, Heroku, PostgreSQL, AWS (EC2, Elastic Beanstalk, CloudWatch, S3, SES, SNS), Photoshop CS5 Areas of Exposure: HTML, CSS, PHP, Javascript, Tomcat/Apache, Java, Spring MVC, SSL, SQLAlchemy, Maven
