Who I am

About

Frank Dessalli

Guidewire-certified Full-Stack Developer with 5 years of enterprise integration experience across three countries. I design the flows that connect Guidewire PolicyCenter to the rest of an insurer's systems — Integration Gateway, App Events, JMS, Apache Camel and Gosu.

On the platform side, I build Java / Spring Boot back ends and Angular front ends: healthcare interoperability (FHIR), municipal-service portals, logistics platforms, CI/CD automation. I have also shipped SaaS products solo, from design to production, payments included.

Outside of code, I publish on my YouTube channel — dev advice, lessons learned and reflections on the craft.
