    Software Engineer / Systems Architect / Biz Logic Understander I’m a senior-level software developer located in Austin, TX. With nearly two decades of professional development experience, I’ve built my skill set while simultaneously adapting to the ever-changing tools available within my trade. Given this, I’m relatively agnostic when it comes to a tech stack and well able to make recommendations and decisions regarding available technology. I have worked as a solo tech lead, tech team lead, systems architect, and as CTO of multiple venture-backed startups in NYC. I left the startup scene and returned to consulting and freelance work 2 years ago. In September, I relocated to Austin to work on-site with a client that has become an employer. So, I do have a 9 to 5 job. I’m working here on the challenges of operations and process optimization within a high-volume factory and sales contact center. During the week, our systems and people have a “touch point” with customers and prospective customers about every 10 seconds.
