What I'm looking for

I'm seeking to contribute to scalable and secure solutions, following best practices in architecture, testing, and deployment.

At Motiron Technologies, I developed a REST API for chemical product management, covering registration, regulatory approval, traceability, and safety compliance.

I implemented a modular DDD architecture with JWT and role-based access control, including hierarchical validations and an approval workflow for chemical registration requests.

I also developed a statistical dashboard and integrated AWS S3 for attachments and AWS SES for notifications. I used Prisma ORM and PostgreSQL to support data modeling, transactions, and data integrity.

At Jala University, I contributed to the Qatu E-commerce and Collaboration Platform projects, working on REST APIs, frontend integration, microservices, authentication, and automated testing.
