A highly experienced Interim Software Engineer and Data Architect. Expert in data modelling, data formats, data transformation, storage solutions, validation tools, query languages, APIs and services.I understand the importance of my client’s data, whether that be scientific measurements, financial information, technical documentation, or archival records. I know how to design and build robust end-to-end systems that deliver data securely to my client’s users so that the information they need is always at their fingertips when they need it.Some recent successes have included:1) transforming The National Archives' (UK) catalogue data to Linked Data and building a web-based editorial application for a new Pan-Archival Catalogue system2) building secure message services for HMRC, which were key to delivering government support to UK businesses during the COVID-19 pandemic3) working with British Airways Engineering to transform their technical documentation to meet the S1000D standard, enabling maintenance teams to access these documents via iPadI am a strong advocate of international standardisation. I believe my clients should be able to move their data between different storage solutions without being locked into proprietary formats. I strongly support the standards and recommendations of bodies such the W3C, ASD, OASIS, OpenAPI and the OGC.I am also a firm advocate of developing and using open-source software, wherever this can be clearly demonstrated to benefit clients. I believe open-source software frequently offers more flexibility and cost savings compared to proprietary software.Java | JavaScript | Scala | SPARQL | SQL | XQuery | XSLT | Cascading Style Sheets (CSS) | DocBook | Extensible Markup Language (XML) | Hypertext Markup Language (HTML) | Java Message Service (JMS) | JavaScript Object Notation (JSON) | JSON Web Token (JWT) | Resource Description Framework (RDF) | Open Digital Rights Language (ODRL) | S1000D | Security Assertion Markup Language (SAML) | Standard Generalized Markup Language (SGML) | Simple Knowledge Organization System (SKOS) | Terse RDF Triple Language (Turtle) | The Semantic Web | Web Ontology Language (OWL) | XML Path Language (XPath) | XML Schema Definition (XSD) | Apache Jena | Pentaho | Play Framework | RDF4J | Spring Framework | Amazon Neptune | Amazon S3 | Common Source Data Base (CSDB) | eXist-db | Marklogic Server | Microsoft SQL Server | MongoDB | Neo4j | Oracle | Protégé
