Background

About Ciprian Radu

I am focused on Code Quality. I deliver the right things, done right! I am passionate about Computers and Sci-Fi. I am curios. I like to explore. I like to constantly learn, to improve myself. I like to take on hard challenges. I am serious, dedicated, with a strong expertise in back-end applications. I like to be as professional as I can. I am an aspiring Software Craftsman (https://manifesto.softwarecraftsmanship.org/). With a PhD in Computer Science, I started over ten years ago to explore, study and research in the field of Artificial intelligence (AI). Currently I am a Software Engineer at Visma. I promote Clean (Hexagonal) Architecture, the API-First approach to building Products, Trunk Based Development. I have a DevSecOps mindset. Notable achievements: • Architected and developed (from scratch) a new mobile Authenticator app, for Android and iOS, with Flutter. It allows users to sign in with push notifications. The app available in Google Play and Apple App Store. • Effectively migrated legacy software systems into Cloud Native software systems. • Rewritten APIs to be standardised, using the OpenApi Specification. • Migrated applications from Payara to Spring Boot (and Java 8 to Java 17). • Rewritten the entire delivery pipeline with Amazon Web Services (AWS) Developer Tools and GitHub Actions. We obtained an end-to-end automated CI/CD pipeline that drastically improved the Delivery Lead Time. • Architected systems to use AWS Fargate instead on AWS EC2. Promoted the use of AWS Lambda (Python and Node.js runtimes), SQS, SNS, AWS API Gateway, CloudWatch, X-Ray. • Architected a scalable mocking solution solely based on AWS. This replaced a cumbersome monolith used to mock several APIs. • Drastically increased the Code Quality by using Quality Gates with SonarQube, and by promoting better testing processes. • Process for keeping all systems up to date, from a security perspective, by using services like Snyk, Coverity and GitHub Dependabot. • I improved the collaboration in the Development Team. • I significantly improved the observability of the entire Platform.
