Top 1% of Freelancers on Upwork (since 2014). Bringing software engineering expertise to the boardroom and to high-risk, at-risk, or high-impact projects. You'll find me skilled in most tech stacks, conversant in Machine Learning and AI systems, comfortable with big data systems and IoT solutions, and a professional who will tell you what you need to hear about the status of the project or your business–even when it's not a pleasant or comfortable conversation. When not busy summiting the Dardanelles and enjoying breathtaking vistas in the Sierra Nevadas, you'll find me saving my clients time and money, solving perplexing automation and data management challenges, automating manufacturing lines, training teams, and making businesses great again. 😜 My programming journey started at the age of 10 with PocketC, a C-variant for PalmOS (^_^). From there, I've added front-end (HTML/CSS, JS, etc.) and back-end (PHP, Linux, Go, Ruby, Python, Java) technologies to my tool belt, becoming an accomplished OO PHP and full-stack development lead. But more than development experience, I've integrated everything I've learned about business and marketing strategy, natural planning, and project management to couple technical solutions with business strategy to accelerate client success. My consulting journey in marketing began more recently in 2016, when I dove headfirst into training by Russell Brunson, Ryan Levesque, CopyHackers, Todd Brown, Ryan Deiss, and DigitalMarketer. Since then, I've discovered an uncanny proficiency in multi-channel media buying strategy and deeply integrated analytics to inform and drive growth strategies. In 2020, I worked as a fractional CMO in the crowded protein supplement space and helped drive revenue growth of 50% for an e-commerce company. Other notable marketing clients have included the marketing strategy and systems that created a 7-figure education business, and solving "unfixable" problems in an 8-figure ecommerce company. In 2020-21, as a fractional CTO, I brought an internal middleware development project to completion, built an additional vendor API on top of it, hired and trained the IT team, and managed the strategic vision for technology within the company. The fusion of senior staff software engineering with advanced digital marketing strategy creates an unstoppable skillset and adds significant value to any leadership team. When you hire me, you get efficient problem-solving, actionable strategy, and strong leadership for the technical component(s) of your business. One of my favorite web projects from the past include an emergency radio feed processor that I built using Ruby on Rails, Sidekiq queueing, a set of Python scripts, and a complex Linux AWS architecture. That client has already made his money back 14X over. Another favorite project because of the challenging requirements involved a completely custom inventory management system for a government office. An investigator's office hired me to digitize the management of their evidence room. They had no audit process, stacks of paper that were difficult to manage, no clear chain of custody, and no way to know for sure where to find a piece of evidence. I built an entire end-to-end system that included a clear chain of custody, audit and report features, a management interface for customizing almost every form, a search function. I gave them insight into where everything was at all times. This project has saved their office at least 10X the project's cost in payroll alone, not including other factors like productivity gains and loss prevention. Since joining Elance in 2013, I've risen to the top of 5-star US freelancers by demonstrating integrity, reliability, quality communication, and abstract problem-solving skills. I specialize in complex systems that solve challenging business problems to make my clients more time and money. I have some of the happiest clients around. Will you be one of them? ;-)Ruby
