Software Engineer

Yorosis Technologies Inc

Dec 2024 - Aug 2026

Maintained 5+ scalable microservices using Java, Spring Boot, REST APIs, and Spring Data JPA, following layered architecture principles to improve modularity and maintainability across backend services. Implemented OpenFeign for synchronous inter-service communication and RabbitMQ for asynchronous event-driven workflows, enabling reliable, decoupled communication across 5+ microservices and reducing service downtime during peak loads. Secured REST APIs using Spring Security and optimized 5+ SQL queries using Spring Data JPA, cutting query response times and improving overall API performance; performed database analysis using DBeaver. Streamlined version control using Git, managing feature branches, pull requests, and code reviews within a team of 2–3 developers to maintain clean, production-ready code. Reduced redundant database calls by implementing Redis-based caching with TTL eviction, improving response times for short-lived application data. Automated 20+ Cypress end-to-end test scenarios using JavaScript over the last 4 - 5 months, covering UI workflows, form validations, and API-driven flows — reducing manual QA effort and catching regressions earlier in the release cycle.
