PROFESSIONAL EXPERIENCE

JPMorgan Chase, Texas Software Developer

January 2025 – Present

• Architect large-scale distributed systems using Java, Spring Boot, microservices, and event-driven patterns, supporting enterprise platforms processing millions of requests per day.

• Design cloud-native services on AWS using EKS, ECS Fargate, and Lambda, enabling multi-AZ fault tolerance and maintaining 99.99% availability for customer-facing applications.

• Lead the decomposition of monolithic applications into 15+ domain-driven microservices, reducing deployment dependencies by approximately 40% and enabling parallel development across engineering teams.

• Optimize application performance using asynchronous processing, non-blocking I/O, virtual threads, and connection pooling, improving p99 and p999 latency by 30% to 50% during peak traffic periods.

• Improve API responsiveness by optimizing PostgreSQL query plans, implementing read replicas, and tuning connection pools, ensuring SLA compliance under sustained high concurrency.

• Implement event-driven workflows using SNS, SQS, Lambda, and EventBridge, processing large volumes of events daily with idempotency and resilient failure recovery mechanisms.

• Automate infrastructure provisioning using Terraform and Helm and enforce security policies through OPA Gatekeeper, improving environment consistency and reducing configuration drift.

• Implement Redis-based caching strategies for frequently accessed metadata, reducing downstream service calls and lowering cloud infrastructure costs during high-frequency workloads.

• Lead technical design discussions by defining service contracts, domain boundaries, and integration strategies across distributed systems and cross-functional engineering teams.

• Develop reusable and responsive user interfaces using React, TypeScript, HTML5, and CSS3, integrating frontend applications with Spring Boot microservices and enterprise APIs.

• Design modular React architectures using reusable components, Context API, and Redux Toolkit, improving maintainability and accelerating feature delivery.

• Define frontend-backend integration patterns using REST and GraphQL APIs, optimizing data retrieval and reducing unnecessary network requests.

• Improve application responsiveness through lazy loading, code splitting, memoization, and efficient rendering strategies.

• Implement frontend testing standards using Jest and React Testing Library, improving code quality and reducing production defects.

• Design and maintain CI/CD pipelines supporting automated testing, zero-downtime deployments, and rollback strategies for business-critical applications.

• Drive incident triage, root cause analysis, and remediation efforts for production systems, improving service reliability and operational readiness.

• Mentor engineers through code reviews, design discussions, and troubleshooting sessions, promoting engineering best practices and improving team effectiveness.

Optum, India Full Stack Java Developer

June 2020 – December 2023

• Developed secure REST, GraphQL, and gRPC APIs using OAuth2, JWT, rate limiting, adaptive throttling, and distributed caching, supporting high-throughput, low-latency production traffic.

• Optimized database performance across PostgreSQL, Oracle, and MongoDB by tuning queries, indexes, and connection pools, reducing API response times by approximately 25% to 35%.

• Built asynchronous processing pipelines using CompletableFuture and thread pools, increasing throughput and improving resource utilization without additional infrastructure costs.

• Designed data-intensive services using PostgreSQL and Redis, implementing caching strategies, query optimization, and connection pooling to meet strict latency and reliability requirements.

• Implemented end-to-end observability using OpenTelemetry, Prometheus, and Grafana, reducing mean time to recovery by approximately 35% through improved tracing and diagnostics.

• Developed reusable frontend components using React, TypeScript, HTML5, and CSS3 and integrated them with backend services through REST and GraphQL APIs.

• Implemented client-side routing and state management using React Router and Context API, improving application scalability and maintainability.

• Built responsive and accessible web interfaces, ensuring consistent user experiences across browsers and devices.

• Partnered with product owners, designers, and backend engineers to deliver end-to-end full-stack solutions in Agile environments.

• Participated in system design discussions, API reviews, and production support activities, improving application reliability and operational efficiency.
