EXPERIENCE

PNC Bank Software Engineer Dallas, TX Jun2023 - Present

Built responsive, real-time banking dashboards using React 18 and Redux Toolkit, enabling customers to view account summaries, manage transactions, and receive alerts with <300ms data update latency.

Integrated UI/UX designs by working closely with design teams, translating wireframes and prototypes into responsive, visually appealing interfaces optimized for user experience.

Developed and delivered high-capacity, efficient web applications using ReactJS, NextJS, and NodeJS from the ground up, ensuring alignment with business and user requirements.

Implemented type-safe and scalable front-end modules in TypeScript, reducing runtime errors and improving developer velocity by 40% during frequent product rollouts for the customer onboarding module.

Secured microservices-based APIs using Spring Security and OAuth 2.0 with JWT tokens, enforcing role-based access control for sensitive operations like fund transfers and profile updates.

Developed 15+ RESTful microservices using Java 17 and Spring Boot 3, handling operations like user registration, balance retrieval, KYC checks, and real-time transaction status updates.

Redesigned the payment orchestration workflow using Java 17, Kafka, and Spring Boot, achieving 99.99% reliability during high-volume events (e.g., tax refund season) by introducing dead-letter queues and idempotent processing.

Orchestrated inter-service communication through Apache Kafka, enabling asynchronous processing of payment events, fraud alerts, and notifications with guaranteed delivery across distributed services.

Configured Swagger for automated API documentation, allowing seamless collaboration between frontend and backend teams and reducing integration bugs during third-party system onboarding.

Achieved 90%+ test coverage across microservices using JUnit 5 and Mockito, validating complex business logic for fraud detection and transaction workflows under multiple edge-case scenarios.

Used Postman for API contract testing, simulating multi-step workflows like bill pay and multi-factor authentication, catching 20+ integration issues before production release.

Integrated MySQL with Spring Data JPA and Hibernate ORM to persist customer profile, payment history, and account configuration, optimizing queries for faster backend performance under load.

Developed scalable applications using NoSQL DBs, achieving significant improvements in query response times and system uptime

Containerized backend services using Docker, ensuring consistency across development, testing, and production environments and reducing on boarding time for new developers.

Implemented secure AWS Lambda functions by integrating with VPC’s to restrict network access and enforce private connectivity for sensitive workloads.

Configured API gateway throttling and rate limiting to protect Lambda endpoints from abuse, denial-of-service attacks, and excessive traffic.

Deployed and managed scalable microservices on AWS EKS (Kubernetes), enabling zero-downtime deployments and auto-scaling during peak usage like payday or month-end.

Leveraged AWS S3, RDS, and Lambda to handle document uploads (e.g., ID proof), scheduled batch processing (e.g., interest calculations), and secure data backups.

Used Terraform to provision AWS infrastructure, including RDS, VPCs, EKS clusters, and S3 buckets, allowing repeatable deployments across dev, QA, and prod environments.

Analyzed structured and unstructured logs with Splunk, identifying patterns in customer error reports and optimizing retry logic across payment and authentication services.

Automated builds and deployments via Jenkins CI/CD pipelines, integrating static analysis, test runs, and container image pushes to ECR, reducing manual errors and speeding up delivery.

Collaborated with cross-functional teams to test and refine user experiences for services like loan application and credit score tracking, ensuring end-to-end flow between React front end and Spring Boot APIs deployed on AWS.

Infosys Molina & Aetna Healthcare Hyderabad, India Jun 2020 – Jun 2022

Designed and implemented secure, scalable microservices using Spring Boot, OAuth 2.0, and JWT to manage patient health records, appointment scheduling, and real-time notifications ensuring HIPAA-compliant access for over 10,000 daily users across multiple hospitals.

Built core microservices using Spring Boot and Java 8 to manage patient health records, appointment scheduling, and digital prescriptions in a modular and scalable architecture.

Integrated JWT tokens within REST APIs for stateless session management, ensuring fast and secure identity propagation between services in the EHR (Electronic Health Records) module.

Designed relational schemas and implemented database access using JPA and Hibernate to manage structured data like patient demographics, treatment history, and billing records in MySQL.

Built asynchronous messaging pipelines using Apache Kafka to deliver real-time appointment alerts, medication reminders, and wearable health device updates with minimal latency.

Created and exposed RESTful APIs using Spring Boot and documented them using Swagger, allowing frontend teams and third-party insurance systems to seamlessly integrate with core services.

Used JUnit5 and Mockito to write unit and integration tests for modules like user management and billing, achieving over 85% code coverage across core functionalities.

Implemented service-level monitoring with Prometheus and built custom dashboards in Grafana to visualize system health, latency, and uptime across patient interaction modules.

Built an end-to-end real-time health monitoring pipeline using Apache Kafka and MongoDB to ingest and store wearable device data (heart rate, BP), enabling doctors to remotely monitor critical patients and trigger alerts for anomalies with minimal latency.

Developed scheduling and reminder logic in Java8 using features like Streams and Lambda expressions, allowing efficient processing of patient notification queues.
