    After many years working in roles ranging from Director, VP, Head of Engineering, or Head of Data for startups and established companies, I now provide those services on a contract consulting basis. Via Upwork specifically, what I am hired for is usually data analysis and visualization or voice UX. (Outside of that my current projects are as a fractional CTO, helping startups build their teams and platforms). A cost-effective way to hire me that clients are choosing more and more is to have me do a few hours of consulting provide guidance to your internal team or another Upwork contractor. Or I am happy to do the work directly myself. I have a clear understanding of typical business requirements and use cases, so you can save some time on explaining those. Give me your goals and as much or as little specific direction as you want, and I'll take it from there. For data analysis and visualization, my core comptency is with Google BigQuery and Google Datastudio. I use BigQuery to automate the heavy lifting of analysis and preparation of the data, and prepare data sources that have exactly what Datastudio needs and no more. This keeps the data visualization performing well. I am not a visual designer but I can prepare a clean and professional reporting dashboard that takes full advantage of the drilldown, filtering, and other interactivity the platform provides. If needed I can work directly with more or less technical stakeholders and help turn their overall goals into specific requirements, and then execute them. Of course the data does not have to be in BigQuery; I am familiar with using a variety of connectors and import automation to pull from many different data sources. Most importantly I have successfully solved real business problems with this platform for many years; for example, analyzed LTV and thereby ROI on marketing spend, and analzed subscription revenue for things like price sensitivity and retention, generating insights that allowed companies to scale up revenue. For voice UX, my main experience is with Amazon Alexa. I have been building Alexa skills since 2016 and I know the platform in detail. Tell me what you would like to accomplish and I can tell you what the platform allows or doesn't allow, and suggest features you may want to take advantage of. I can work from a voice flow you provide me, or write out flows for your approval. I am also very familiar with AWS and have all the infrastructure necessary for development on my own account so we can get started immediately; I can then set up all the required services in your AWS account in a secure way, and transfer the skill for further development, testing, and release. I am very familiar with getting skills through the certification process and can anticipate or quickly fix all the common objections from Amazon's reviewers. I can also set up monitoring and analytics usign the Alexa platform's built-in capabilities as well as connecting external analytics systems if needed. Thanks for reading and I look forward to discussing your project.
