Self-Employed•  February 2023 - Present•  Dublin

I self-published my debut novel, From Terror to Valor: Echoes and Shadows, which lies the Suspense, Action and Thriller genres. Launched across nineteen digital book stores on September 11th, 2024, the novel delves into the protagonist's journey navigating the war on terror, along with the complexities of the international intelligence community. I managed the project through Jira, and also Confluence. This allowed me to streamline the writing process in a structured manner. My novel writing will move into web serials for my second project, Hindsight Station. Given the incredible learning curve from my debut project, Hindsight Station will be a fully part-time endeavor.
