Software Engineer (Full stack), Shopify June 2024 - Present San Francisco, CA

• Designed and implemented high-throughput, scalable Java microservices using Spring Boot and Spring Cloud for the Sidekick API performance initiative (multi-tenant commerce SaaS), reducing Sidekick API latency by 35% in load tests while sustaining 10K+ concurrent virtual users.

• Migrated legacy-style monolithic modules into decoupled Spring Boot microservices as part of the Core Platform Migration program, leveraging AWS Lambda for event-driven tasks, resulting in an estimated 20% reduction in infrastructure costs under realistic traffic profiles.

• Developed and enforced OAuth 2.0 and JWT security across Java services for the Payments Authorization & Billing feature to secure data flows and support PCI-DSS compliance expectations for payment integrations (tokenization, encryption in transit/at rest, auditable logs).

• Containerized Java microservices with Docker and automated deployments on Kubernetes (EKS) under the Platform Reliability & Operations track, applying 12-factor principles; synthetic monitoring over the evaluation period showed 99.9% service uptime.

• Authored robust GraphQL schemas with the Netflix DGS framework for Merchant Order Summary & Catalog views

(GraphQL enablement), reducing frontend over-fetch by 30% and significantly improving measured page-load performance on read-heavy views.

• Integrated AI/ML NLP pipelines through TensorFlow Serving and gRPC Java clients, streamlining query resolution and increasing response accuracy by 40% against a labeled validation set.

• Built dynamic, merchant-facing UI components with React and TypeScript, integrating with backend REST endpoints to boost user engagement by 25% on key workflows (task completion and repeat actions).

• Ensured WCAG 2.1 accessibility and implemented SEO enhancements, including server-side rendering (SSR) and meta-tag management for improved storefront discoverability in search audits.

• Collaborated in Agile/Scrum sprints, leading planning, pair-programming, and TDD with JUnit and Mockito, accelerating feature delivery by 15% per sprint in tracked velocity.

• Mentored junior developers on Java best practices and microservices architecture, improving overall code quality by 25% as measured by SonarQube.

Software Development Engineer, Adobe August 2019 – July 2023 India

• Assisted and enhanced scalable backend services for Adobe Experience Cloud using Java and Spring Boot, for the Campaign Workflows, delivering robust enterprise-level features.

• Collaborated with cross-functional teams to build and integrate RESTful APIs for the Marketing Automation and Customer Identity services, ensuring efficient data flow between frontend and backend systems in high-traffic environments.

• Designed and maintained CI/CD pipelines using AWS CodePipeline and Jenkins, for multi-tenant service releases, to automate Java application deployments, reducing release cycles by 25%.

• Implemented comprehensive unit and integration testing with JUnit and Mockito for Java services, increasing code quality and reducing production bugs by 30%.

• Conducted performance monitoring and tuning of Java applications, including Asset Rendering and Content Delivery services, identifying bottlenecks and improving average response times by 15%.

• Architected and managed SQL and NoSQL databases for high-volume event and configuration data, to support large- scale data storage and high-concurrency access for backend services.

• Assisted in containerizing microservices with Docker and deploying them on Kubernetes, as part of the Experience Cloud microservices migration, enhancing scalability and fault tolerance.

• Developed dynamic user interface components with React.js for internal admin consoles and reporting dashboards, improving frontend responsiveness and user engagement.

• Investigated and resolved production issues using user feedback, error logs, and priority incidents within customer- facing Experience Cloud modules, increasing customer satisfaction by 20%.

• Created internal automation tools to streamline recurring development tasks, boosting overall team efficiency and reducing errors.
