I have bold experience as an architect, expert developer and tech manager for web-based application development projects for large corporations (check my background information on my profile).
I have also experience working with Lean Startups implementing massive analytics services (google analytics between them), configuring not only funnels for sales/action tracking, but application usage. Also in setting up event-based marketing and mailing platforms integration.
My proposal is to further discuss your initial requirements to get to market as soon as possible, and then take advantage of usage analytics to decide on which parts to improve. Some of this improvements will be by modifying the site design, user experience and interaction, adding social capabilities, reward systems and gamification, as well as re-marketing through behavior-driven email communications.
Let's discuss your initial budget and target time-to-market to see if we reach a commitment to get this done.
Yours,
Anibal
