David Hermoso

I work at Metro Markets GmbH (Metro AG), building Metro/Makro's multichannel marketplace, a first at this scale in the HORECA industry. With 6 markets live and growing, it complements 600+ Metro/Makro stores and our food delivery service. I worked on the product page frontend, ensuring a seamless purchasing experience. Now I'm in the Search & Recommendations team, owning product catalogs, listing pages, cards, filters, optimizing interaction and streamlining the user journey through A/B testing.

I worked (mainly) on network management apps. Projects were challenging: we built UIs for easy-to-use features covering cybersecurity, routing, and WAN/LAN management, with data updating almost every second. The team used HTML, CSS, and JavaScript, with Vue for reusable components, plus internal component libraries shared across apps. Web Workers kept real-time data in sync across clients. We worked in small agile teams. Best practices, and MVP focus, a challenging but amazing experience at OmniAccess.

I had the pride of working at Ryanair, in a fast-paced, international environment, helping digitalize tools used daily to run Europe's favourite airline's flight operations. My team built 5 internal apps from scratch with Angular, automating key business processes. We followed git flow with PR-based code review, working with skilled, multidisciplinary teammates who taught me the value of agile teamwork. I strengthened HTML, CSS, TypeScript, RxJS, NGRX, GraphQL, AWS, Docker, and deploy.

I was working in "Travel circuits" product. The team was in charge of building new features and maintaining the front-end and the back-end full product flow We worked from the database to the UI. The tech stack in the front-end side was HTML, CSS and Vanilla Javascript (in some projects). In another projects We used Angular (with Typescript) and SASS. In the back-end side We used Java 8 with Spring boot.

I contributed to eDreams Odigeo "Flight + Hotel" team, a Product Owner, UX specialist, QA, five developers, and a BA coordinating across teams, in a diverse, dynamic environment. This was rewarding: I engaged end-to-end, from idea to production, iterating through A/B tests, Google Analytics, and UX-led user sessions. Our agile, fast-paced principle: "Fail as quickly as possible to learn, and improve from experience." Stack: HTML, CSS, JavaScript (Backbone JS), Java, with Mercurial/GIT and Jenkins for CI.

I worked on maintaining a web application, and building its new version, in the pharmaceutical robotics sector. Front-end: HTML, CSS, JavaScript (jQuery as main UI library), with Bootstrap 3 as the CSS framework. Back-end (new version): CodeIgniter (PHP framework) and MySQL. I also worked on a separate application built with VB.Net and SQL Server, and made a one-off change to an existing Android app.

Intership in a Microsoft innovation centre focused on Tourism Technologies. I could learn the basics of Microsoft technologies building some apps with C#. Some of the engineers working in this innovation centre were Microsoft MVP, so learning from them was a great opportunity.

I was an internship for 4 months in a Pc Box shop for the repair, maintenance and assembly of new computer equipment by parts. The main tasks were: - Detection of errors in the equipment. - Assembly of equipment. - Maintenance of equipment and replacement of parts. - Installation of Windows and Linux operating systems.
