Work History

Senior Java Developer

Department of Health Care Services
04.2023 - Current
  • Developed RESTful microservices using Spring Boot and deployed them in AWS using Lambda and EC2.
  • Integrated Confluent Kafka for event-driven architecture and used Schema Registry for message schemas.
  • Authored Bash shell scripts to automate file orchestration, cron jobs, and daily job health checks.
  • Designed efficient MongoDB queries and aggregation pipelines to handle unstructured and semi-structured data in healthcare workflows.
  • Modeled NoSQL collections in MongoDB for high-throughput medical claims and eligibility checks with flexible schemas.Used CloudWatch and Splunk for log aggregation and resolving real-time application errors in production.
  • I participated in Agile ceremonies and wrote user stories and technical tasks in JIRA.
  • Configured Jenkins and GitHub Actions pipelines for automated builds, deployments, and testing workflows.
  • Utilized Angular Material (MUI) to follow modern design language system (DLS) and ensure UI consistency.
  • Built and maintained responsive, component-based user interfaces using Angular, HTML, CSS, and JavaScript to ensure seamless interaction with backend APIs.
  • Developed advanced Elasticsearch query DSL scripts including nested queries, bool queries, and function_score queries to deliver highly relevant search results for product catalogs and financial transaction records.
  • Integrated Spring Security filter chains with custom authentication and exception handlers to return consistent error responses (401, 403) with audit context and correlation IDs.
  • Enabled stateless authentication using JWTs and disabled default session management to support scalable microservices running in Kubernetes behind API Gateways.
  • Integrated RxJava with Spring Boot applications for reactive DB access and stream-based event processing pipelines, reducing thread contention and improving I/O-bound performance.
  • Wrote unit tests using Jasmine and Karma, and ensured UI regression coverage with Storybook + Chromatic.
  • Developed secure authentication and authorization mechanisms with Spring Security (OAuth2) to maintain industry-standard access control.
  • Refactored legacy Java codebases to align with microservices architecture and AWS best practices.
  • Created internal documentation in Confluence detailing system workflows, integration patterns, and endpoints.
  • Built dynamic, responsive single-page applications (SPAs) with Angular, collaborating closely with UI designers and product teams.
  • Automated CI/CD workflows and developer tooling using Node.js CLI scripts with npm packages to accelerate build, test, and deployment tasks — tasks that would require more boilerplate and complexity if implemented in Java.
  • Integrated Maven with Spring Boot, enabling streamlined builds, JAR/WAR packaging, and deployment automation.
  • JUnit 5 test suites for Spring Boot services, covering business logic like eligibility validation, payment scheduling, and Kafka message handling, with over 90% branch coverage.
  • Deployed legacy Spring MVC monoliths and REST APIs on Apache Tomcat 9.x clusters, configuring thread pools, connection limits, and context paths for multi-tenant hosting.
  • Used Mockito to mock Kafka producers, DB repositories, and external REST clients (via RestTemplate or Feign), enabling fast, isolated unit tests without external dependencies.

Software Developer

HCL
08.2018 - 07.2021
  • Designed and developed RESTful Spring Boot microservices for transaction initiation, customer profile management, and financial report generation, deployed in production environments using AWS EC2.
  • Built Kafka producer/consumer modules to capture and process real-time transaction events, including fund transfers, balance updates, and fraud alert signals — enabling sub-second latency pipelines.
  • Implemented JWT-based API security using Spring Security OAuth2 Resource Server for customer authentication, token expiry management, and client-specific scope validation — aligned with PSD2-like access models.
  • Applied role-based access control (RBAC) using @PreAuthorize and @Secured annotations to restrict sensitive operations like account blocking, admin overrides, and transaction rollbacks to authorized user roles.
  • Created unit and integration tests with JUnit, Mockito, @WebMvcTest, and MockMvc to validate transaction service APIs and ensure compliance with test coverage thresholds enforced in CI pipelines. Developed Angular 8+ frontend components for customer dashboards, transaction history views, and payment forms using RxJS, Angular Material, and HTTPClient to consume secure backend APIs.
  • Built and maintained real-time data ingestion pipelines using Logstash and Kafka Connect to stream millions of log events daily into Elasticsearch clusters, enabling sub-second search and analytics capabilities.
  • Built serverless AWS Lambda functions with Node.js to implement lightweight, event-driven business logic that scales automatically and minimizes cold start latency, enabling cost-efficient processing pipelines not easily achievable with Java Lambdas due to heavier startup times.
  • Developed and automated Bash scripts for log rotation, job monitoring, and backup verification in RHEL-based environments, reducing manual ops workload by 60%.
  • Tuned Cassandra queries using optimal partition keys and local secondary indexes to support financial reporting workloads like AML flagging and recent transaction history.
  • Implemented Kafka dead-letter handling and retry logic to guarantee message delivery integrity and prevent transaction loss in case of transient downstream service failures.
  • Developed and maintained build scripts using Apache Ant to compile Java code, package JARs/WARs, and automate deployment processes.
  • Integrated PHP-based APIs with Spring Boot microservices for reporting and customer self-service dashboards.
  • Environment: Java 8, Spring Boot 2.2, AWS (EC2, S3, IAM), Apache Kafka 2.4, MongoDB, Cassandra, Jenkins, GitLab CI, Informatica 10.1, Red Hat Linux 7.6

Android developer Intern

UNIQ
08.2017 - 07.2018
  • Developed Android applications in Java, applying modern architectural patterns (MVVM/MVP) and Material Design for maintainable, user-friendly mobile solutions.
