What I'm looking for

I seek senior technical roles building secure, scalable web applications in regulated environments where I can lead architecture, mentor teams, and drive quality and compliance.

I am a Senior Clinical Trial Web Application Developer with over 7 years focused on Clinical Trial Technology (CTT) applications and more than 15 years in software development. I specialize in designing, developing, testing, maintaining, and supporting secure, enterprise-level web applications for regulated environments.

My technical strengths center on Java/J2EE and the Spring ecosystem (Spring MVC, Spring Boot, Spring Security), ORM with Hibernate/JPA, and RESTful API design. I have led migrations from legacy frameworks to Spring Boot, optimized performance (reducing response times by 40%), and implemented improved encryption and web security measures.

I have experience mentoring and leading teams, performing code and database reviews, authoring architectural artifacts, and establishing development frameworks, CI/process documentation, and QA/change-control practices. I have managed projects in e-commerce, telecommunication, finance, and clinical research domains.

I am multilingual (English, French, Portuguese, Spanish) and committed to producing maintainable, secure, and compliant solutions that meet stakeholder needs while coaching and elevating engineering teams.
