What I'm looking for

I’m looking to leverage my software engineering background and fintech domain knowledge in a Technical Business Analyst role, bridging business requirements and technical implementation.

At Worldline SA, I led requirements analysis and technical solution design for a payment-processing platform, connecting business needs with implementation. I worked with Product Owners, Business Analysts, QA and DevOps Engineers to assess dependencies, estimate effort and coordinate delivery.

I also designed and delivered backend solutions for compliance and regulatory reporting using Java, Spring Boot, Oracle and PostgreSQL. I provided technical leadership to a five-member development team and coordinated releases, maintenance updates and hotfix deployments.

As a Java Software Engineer at Worldline SA, I developed backend services for financial transaction processing and contributed to requirements analysis, solution design and sprint planning. I also contributed to Data Warehouse solutions and ETL pipelines for banking and financial reporting systems.

Earlier, I was an Executive Assistant at Ter-Tachatyan Legal and Business Consulting CJSC, coordinating schedules and preparing legal and business documentation. I’m looking to bring my software engineering background and fintech domain knowledge to a Technical Business Analyst role, bridging business requirements and technical implementation.
