Daniel Gomes has a deep experience in web information systems obtained through the research, development and maintenance of innovative online services since the early days of the Internet. He holds a broad set of skills which cover all stages of the lifecycle of an online service, including:- Strategic planning - User experience- Software development- DevOps- Site Reliability Engineering- Quality Assurance- Cybersecurity- Training and disseminationDaniel Gomes can contribute to optimize existing systems and develop successful new services in any organization.- Short biographyDaniel Gomes founded Arquivo.pt (the Portuguese web-archive) in 2007 as follow-up of his PhD thesis and currently leads this public service that provides worldwide unique features (e.g. image and textual search over information archived from the web since the 1990s). Arquivo.pt system manages over 1 PetaByte of data (20 billion web files) distributed over dozens of servers at its own data center. The current software system is the result of more than 25 major releases since 2015. Daniel Gomes dedicated most of his career to developing the Arquivo.pt public service. For this purpose, he developed a wide scope of expertises along time because a web archive is a peculiar information system which is not supported by major suppliers nor web archiving is yet an established area of knowledge. He obtained his PhD in Computer Science with a thesis focused on the design of large-scale systems for the processing of web data to automatically derive evolution trends (Big Data). He has been working in the research, development and operation of web-based information systems since 2001, covering all stages of the lifecycle of a product from theoretical scientific hypotheses to services successfully running for years. He has managed software teams with frequent staff rotation and open-source projects since 2007. He delivered over 200 invited talks and training sessions and published over 57 scientific and technical documents. He was the Chief Editor of the book “The Past Web: Exploring Web Archives” and independent expert to evaluate research activities funded by the European Commission on Information and Communication Technologies.
