Presentation

With over 7 years of experience, I specialize in building high-performance backend systems using Java and Microservices. My expertise lies in transforming complex business requirements into scalable, production-ready solutions, particularly within the E-commerce and Fintech sectors.

Core Technical Stack:

Backend: Java (11/17/21), Spring Boot, Microservices, REST APIs, Kafka.

Frontend: React, AngularJS (Building seamless end-to-end admin panels and dashboards).

Database & Tools: PostgreSQL, MongoDB, Docker, Kubernetes, AWS.

I don't just write code; I focus on system reliability and maintainability. Whether you need to migrate a monolith to microservices or build a robust API from scratch, I ensure the architecture is solid and the delivery is on time.
