What I'm looking for

I want to build fintech microservices and REST APIs in Java/Spring Boot—optimizing performance, modernizing legacy systems, and integrating third-party services securely, while collaborating with product and QA to ship reliable features.

I’m a Software Engineer with expertise in Java, Spring Boot, and Microservices architecture, specializing in fintech solutions. At Perfios Software Solutions, I’ve integrated third-party services (CRM, Valocity, DDE, real-time DMS) and built scalable, Redis-driven batch processing for document uploads and downstream workflows with retries, failure handling, and distributed job locking.

I also develop configurable onboarding and account APIs—building 30+ REST APIs for CASA and upgrading LOS features in Spring Boot—while strengthening data security through encryption/decryption and PII masking. I enjoy collaborating with product, QA, and integration teams to deliver robust, high-performance systems under tight deadlines.
