Profile

Senior Software Engineer with 7+ years of Java backend experience, specialising in distributed microservices architectures for regulated financial systems. At EPAM Systems, I designed and delivered a production credit-scoring platform for a Swedish Tier-1 bank — processing real-time financial data via Apache Kafka, secured through OAuth 2.0 and Spring Cloud Gateway, and deployed on Kubernetes with zero-downtime blue-green releases. Strong foundation in system design, data structures, and clean code practices. Currently deepening expertise in distributed systems and preparing for senior engineering roles at top-tier technology companies.

Experience

Senior Software Engineer
Sep 2021 — Present
EPAM Systems · Udaipur, India
  • Architected a 4-service microservices platform (Data Collection, Credit Scoring, User Management, Report Service) for a Tier-1 Swedish bank, serving thousands of bank officers daily through Spring Cloud Gateway.
  • Built real-time credit score pipelines using Apache Kafka — optimised partitioning strategies to reduce peak-load latency and eliminate message loss under high throughput.
  • Implemented OAuth 2.0 token validation via TokenRelayGatewayFilterFactory across all gateway routes, ensuring zero unauthorised service access.
  • Integrated Redis caching (@Cacheable, @CachePut, @CacheEvict) on credit score lookups, significantly reducing database read pressure.
  • Achieved GDPR compliance for EU financial data using AES-256 encryption and @JsonSerialize(PartialMaskingSerializer) to mask PII in all application logs.
  • Led Java 8 → Java 11 migration — replaced deprecated javax.xml.bind APIs, updated all dependencies, and maintained full regression test coverage throughout.
  • Delivered automated credit score alert notifications via JavaMailSender — eliminated manual polling for bank officers checking score thresholds.
  • Set up CI/CD pipeline (Jenkins → Maven → JUnit/Mockito → Docker → Kubernetes) with blue-green deployment; enforced SonarQube 80% coverage gate on all merges.
  • Centralised observability using Log4j2 + Splunk for structured logging and real-time production monitoring.

Key Project

Credit Score Analysis Tool — Swedbank (Sweden)

EPAM Systems · Java 11 · Spring Boot · Kafka · Redis · OAuth 2.0 · Kubernetes

Production-grade microservices platform enabling a leading Swedish bank to perform real-time credit scoring on customer financial data.
