    My wife and I combined have over 30 years of experience working in Real Estate, my wife as a Broker, and myself as an Agent and Mortgage Broker. We have also worked as Virtual Assistants and Transaction Coordinators over the years for several clients, so together we offer you decades of knowledge and experience in all aspects of Real Estate. We successfully ran our own Real Estate Brokerage Firm for over 18 years and have experience in all aspects of running that business as well. In the past, we have owned multiple single-family rental properties and have experience in rehabbing and flipping houses. During the recession, we worked as full-time Broker Price Opinion agents for lenders turning out on average 700 BPOs (CMAs) a year. We also can offer expertise in the IT field, as we both worked as Network administrators and have worked help desk assisting users with software and hardware issues. This affords us the ability to learn just about any software and database programs you are using with ease. Although we are no longer licensed, we enjoy working from home-sharing our knowledge and experience while helping others. You would essentially be getting two talents for the price of one (our contract would be through my profile only), a virtual team to handle all of your needs. We would like to offer you our services and would love an opportunity to discuss with you in more detail your job requirements and your specific needs for a virtual assistant. We are prepared to handle just about anything you can give us and we're ready to go to work for you. I'm also a 20-plus-year Pro Tools recording engineer and lifelong musician. I am a Riff Writer, Recording Guitarist, Self-Taught Mixing and Mastering Engineer. I'm detail-oriented and efficient but will take the time to get it right, always to the client's satisfaction.

    Welcome to my home here on Upwork! 🏡 Most of my visitors drop by because they are tired of being told that what they’re trying to do “can’t be done” or they are looking for a developer who truly adds value to a project beyond simply completing tasks. An expert that can quickly gain a system wide view, proficiently manage agile development, and that will be a true asset to your project by taking ownership in problem-solving. Providing insight, alternatives, and recommendations on top of being able to understand and execute instructions. What is the development challenge that you are facing right now? Send over an invite to your project, or a direct message, and we can start talking about solutions right away. 🔧 𝐒𝐞𝐫𝐯𝐢𝐜𝐞𝐬 𝐎𝐟𝐟𝐞𝐫𝐞𝐝: 𝐅𝐫𝐨𝐧𝐭 𝐚𝐧𝐝 𝐁𝐚𝐜𝐤-𝐄𝐧𝐝 𝐃𝐞𝐯𝐞𝐥𝐨𝐩𝐦𝐞𝐧𝐭: Planning, Design, Documentation, Coding, Testing, Debugging, Deployment, Monitoring, and Maintenance.
