What I'm looking for

I'm targeting a Senior Back-end Engineer role focused on building scalable, secure, high-performance distributed systems, particularly payment systems, cloud-native architecture, and production reliability.

At Publicis Sapient, I design and develop scalable REST APIs for account microservices using Java and Spring Boot. Optimized query execution and caching improved response time by about 30%.

At Reach, I developed event-driven workflows with AWS Step Functions and serverless microservices with AWS Lambda. I also integrated a payment gateway for secure financial transactions and built authentication workflows for critical user operations.

At Accenture, I built backend services for product management platforms and optimized data retrieval and archival strategies. I also integrated legacy mainframe systems with distributed applications.
