    Ionic, Capacitor, and Angular I have been on every step of the Ionic and Angular journey since 2015 as a developer using these tools to build cross-platform mobile apps and data-centric web apps. Ionic and Capacitor are an excellent combo for many businesses. These versions provide the best performance yet and, when used with Angular features, such as animations, results in a superb user experience. Angular along with RXJS is also a powerful platform for building web apps that either support Ionic applications or are stand-alone. Having the same developer working on both the Ionic mobile app and a supporting web app can make valuable business sense from efficiency and productivity standpoints. Cypress integration tests improve developer confidence in creating and releasing application updates. I can efficiently apply advanced Angular, Ionic, Capacitor capabilities to help you succeed with your project. My work can either be through hands-on development or with advising or coaching. I insist on being responsive to my clients and also providing clear communication and detailed documentation as it pertains to a project.

    As an accomplished Full Stack Engineer and Chief Technology Officer, I've consistently delivered elegant and thoughtful solutions to projects, while adeptly leading teams and delegating tasks. My approach combines analytical prowess with creative thinking. I also excel at communicating complex concepts effectively. In my most recent role as CTO, I was instrumental in understanding the need and initiating a migration to the cloud of a news/editorial website. As a full stack engineer, I worked on an MVC LAMP stack, developed and leveraged numerous RESTful APIs, and managed databases in MySQL and SQL Server. I created a custom, AJAX-driven CMS portal for our team to manage an array of site content (e.g., news, articles, interviews, music charts). I was also the architect of a secure, self-service music download system (including streaming) that enables record label clients to promote new releases (via targeted emails) to vetted radio industry professionals, which generated a significant, six-figure revenue stream for the company and praised for its ease-of-use. I also implemented a billing system that integrated with Heartland Payments. I also have past experience building e-Commerce solutions. What I bring to the table: • 20+ years as a database architect, web and software developer, who is extremely proficient in SQL (MySQL, MS SQL, Oracle, DB2), Linux and MVC frameworks, and I’m continually learning new platforms as well as NoSQL, AI/ML and big data solutions. • I have knowledge of a wide breadth of coding languages including PHP, JavaScript, C++, Java, C#, Python and Ruby. I also have some experience with SwiftUI (iOS). • I keep up to date on newer coding languages (Go, TypeScript), back-end frameworks (NodeJS) and front-end libraries like React. • I keep pace with the latest cloud technologies on AWS and GCP, including containerization (Docker/Kubernetes), microservices/serverless architectures and NoSQL databases. • I have experience with audio/video HLS streaming and encoding • I’m an avid problem solver and critical thinker with unique, efficient solutions. • Knowledge and experience with cloud environments in AWS and GCP, along with Docker, Kubernetes and Terraform for infrastructure and application deployment. • I'm adept at leading teams and working as a team member. • I’m a keen listener, working with my team to understand and interpret clients’ needs and deliver well-designed solutions. • I’m an excellent writer, able to break down complicated topics in ways that can be easily explained to beginners or laypersons without having to resort to jargon. In other words, I’m able to take off my engineering cap when the need arises. A bit more about me: I'm an avid music lover who keeps up with the latest music. I dabble in writing music, mixing and audio recording/engineering. I love the arts, science, nature, hiking. I'm also very witty and a unusually keen observer.
