Message

On Wayfair’s Advertising platform, I designed and delivered Java and Spring Boot microservices on Google Cloud Platform for sponsored-product campaigns, bidding, and ad-serving workflows. I also built REST APIs for campaign management and advertising reports.

I previously worked on McGraw Hill’s digital platforms, designing AWS architecture and building services for learning-platform features. I implemented API security with OAuth2 and JWT and modeled MongoDB data for content and learner activity.

At REMOTE TECHNOLOGIE (MX) C1, I developed Java solutions for risk systems at Capital One Bank, with a focus on data integrity and security. I also developed REST APIs and secured them with OAuth2 and JWT.

At TECG URUS, I guided systems engineering projects from concept through production and implementation, and defined architecture for JEE, .NET, and mobile projects. I also created technical training materials on development standards. My certifications include Java 11 Programmer and Microsoft Certified Professional.
