Oussama Essamadi

Technical senior specialist, NTT Data

Tangier · April 2025 to now

Full-stack engineer and stream lead for Intesa Sanpaolo. On Documentum MSID, a document management platform built from scratch, I deliver it end to end: Java 17 Spring Boot microservices over REST and GraphQL, an Angular 19 front end, fine-grained access control, versioned storage and search on Elasticsearch. Around it, I improve the existing microservices and the shared Angular libraries, and write the JasperReports templates for invoices and regulatory statements. Java 21, 17 and 8, Spring Boot, Angular, Maven and GitLab CI/CD.

Software engineer, NTT Data

Tangier · December 2022 to March 2025

For Intesa Sanpaolo, I took over the commercial stream’s Anage portal and led its move from Angular 4 and Java 6 to Angular 7 and Java 8, clearing critical security issues and bringing the build up to date, from Maven to Gradle. On the CJHUB suite I led the accessibility work that brought it to WCAG 2.1 AA, and rolled out a new design system across every one of its apps, with the design, QA and operations teams, without downtime.

On xNGAS, a serverless platform on AWS in Python: legacy code refactored and better tested, new microservices, infrastructure as code with the CDK, CI/CD pipelines with blue/green releases, REST, WebSocket and event-driven APIs on Lambda and API Gateway, queues and notifications over SQS and SNS, and large data migrations with Glue and Athena.

On BuDDy, a web app for Cucumber test results that I designed and led: live dashboards and PDF and HTML reports, step suggestions and flaky-test analysis with OpenAI’s models, a Monaco-based Gherkin editor, and Jira plugins that link tests to issues. Angular, Express, Java, PostgreSQL and Docker.
