Hi, I'm
I build enterprise software, mobile products and integrations at Bandalux while pursuing a Master's in Cybersecurity and Privacy at UOC. Backend, Android, APIs, Dynamics 365, SharePoint and a security-first mindset.
Computer Engineer from UOC with over 5 years of experience in software development. Currently pursuing a Master's in Cybersecurity and Privacy, strengthening a security-first approach across product, backend and integrations.
At Bandalux I build the eBA configurator, the Android app and B2B flows across backend, REST APIs, Dynamics 365, SharePoint and Microsoft services. Before that, at Seidor, I worked with SAP Business One and enterprise integrations.
I enjoy combining programming, architecture, applied security, AI and product thinking to build software that is robust, useful and maintainable.
