PROFESSIONAL EXPERIENCE

7- Eleven Apr 2024 - Present McLean, VA

Built and maintained Spring Boot microservices that ingest over one million inventory and deliver records from MongoDB and SQL Server, forming a unified data backbone for the Supply Chain Analytics Portal.

Designed high-performance filter and pagination endpoints with optimized SQL and MongoDB queries, preventing UI timeouts during complex multi-criteria searches.

Implemented robust security with Spring Security and JWT, enforcing role-based access to sensitive supply-chain data.

Developed responsive React and TypeScript components including a virtualized Excel-style grid and interactive dashboards, so large datasets remain fast and fluid on any device.

Orchestrated real-time data flows using asynchronous fetching and disciplined state management, ensuring instant view updates when users adjust filters or date ranges.

Automated the CI/CD pipeline in Jenkins, packaging Docker images and deploying to AWS ECS and S3, shrinking release cycles from days to hours.

Safeguarded API contracts by generating Swagger documentation and running end-to-end Postman regression suites on every build.

Boosted backend performance by profiling services, adding targeted database indexes, and refactoring data-access patterns cutting critical query response times in half.

PNC Bank Jan 2023 – Mar 2024 San Antonio, TX

Built modular Spring Boot microservices with Hibernate ORM to create, update, and report on vendor profiles, payment records, and contract metadata inside PNC’s internal portal.

Enforced role-based security across every endpoint using Spring Security with JWT and fine-grained method guards, protecting sensitive financial workflows.

Delivered intuitive search, detail, and workflow screens in Angular and React with TypeScript, adding form-level validation and reactive status refresh so users saw payment changes instantly.

Tuned complex SQL queries on SQL Server and DB2, introducing indexes and query plan hints that cut vendor-payment lookups from seconds to sub-second latency.

Wrote end-to-end test suites in Postman, integrating them into Jenkins to block merges on failed regression runs and keep service behavior predictable.

Published and versioned Swagger / OpenAPI specs straight from code, enabling easy onboarding for downstream teams and outside auditors.

Containerized services and orchestrated deployments through Jenkins pipelines and Maven, ensuring repeatable builds and smooth rollbacks.

Mentored new hires with detailed system walkthroughs, diagramming the full payment request path from UI action through service layer to database commit.

Intuit Inc Aug 2020 – Jul 2022 India

Contributed to a cloud-native Spring Boot service that synchronized QuickBooks customer profiles with external billing systems, exposing secure REST endpoints and using RabbitMQ events for reliable data propagation.

Built interactive Angular screens with Material Design, wiring components through RxJS streams and centralized state in NgRx to keep transaction views instantly up to date.

Set up end-to-end pipelines in GitHub Actions, enforcing static analysis with SonarQube and running JUnit and Mockito test suits before every merge to maintain build integrity.

Published a unified GraphQL gateway with Apollo Federation, letting internal teams query accounting, invoicing, and customer data through a single, well-documented schema.

Practiced TDD inside two-week sprints, rolling out new features behind LaunchDarkly flags and monitoring performance and errors in real time with Datadog dashboards.

Documented API contracts and deployment steps in Confluence, improving onboarding for the next trainee batch.

GGK Tech Dec 2019 – Jul 2020 India

Contributed to a responsive customer-onboarding module with Angular 8, TypeScript, and Bootstrap, ensuring consistent behaviour across desktop and mobile during a 7-month tenure.

Helped build RESTful services in Spring Boot with Hibernate, implementing CRUD endpoints for product and customer data and gaining solid hands-on ORM experience.

Added entry-level JWT authentication via Spring Security, tightening access controls and learning enterprise security patterns.

Optimized front-end performance by applying code-splitting, lazy loading, and Webpack bundle analysis, trimming initial load time and boosting Lighthouse scores.

Supported Agile sprints with Git, Jenkins, and Docker; wrote unit and component tests in JUnit and Karma, collaborating closely with senior developers, UI/UX, and QA to keep regressions out of main.
