My work bridges cutting-edge backend systems with seamless user experiences, from building scalable microservices that serve millions of users, to designing secure shopping flows powered by Meta Pay and Amazon integrations. I’ve developed and launched AI-driven ad monetization systems that personalize voice-activated campaigns in real time, contributing millions in ROI while advancing how users interact with ads. On the commerce side, I help create frictionless checkout journeys inside the glasses, transforming how people discover and purchase products on the go. Beyond backend systems, I work across the stack—designing companion app interfaces with React/TypeScript, streaming telemetry with Kafka and gRPC, and optimizing observability with Prometheus and Grafana. I thrive in cross-functional pods with AI/ML, product, and security teams, where I focus on architecting solutions that improve performance, reliability, and personalization at scale. I’m passionate about merging AI, real-time systems, and commerce into wearable technology that reshapes how people engage with the world. ### Software Engineer @ Shopify Jan 2023 – Jan 2024 At Shopify, I work as a Full Stack Software Engineer contributing to Shopify Capital, where I design and build scalable, reliable, and secure financial services that empower merchants. I develop and maintain backend microservices in Java and Spring Boot to support loan disbursement, credit scoring, and repayment workflows, ensuring high reliability and reduced processing times for thousands of merchants. My work bridges backend systems with rich front-end experiences, including React.js and Angular dashboards with GraphQL, enabling merchants to gain real-time insights into their credit and loan statuses. I integrate payment APIs like Stripe Treasury and WebBank, while implementing OAuth and Spring Security to ensure compliance with PCI-DSS, SOC2, and GDPR standards. I leverage modern cloud infrastructure, deploying containerized services on Kubernetes and automating CI/CD pipelines with GitHub Actions to maintain zero-downtime deployments. Additionally, I optimize data storage, caching, and financial ledger consistency using MySQL and Redis, while applying event-driven architectures and Apache Kafka to process transactional events in real time. Collaborating closely with cross-functional teams, including QA, DevOps, and partner banks, I deliver secure, efficient, and merchant-centric financial technology solutions that scale globally. ### Software Engineer @ Accenture in India Jan 2019 – Jan 2022 At Accenture, I contributed as a Software Engineer to the Enterprise Digital Platform (EDP), delivering scalable and high-performance solutions for enterprise clients. I specialized in designing and maintaining Java Spring Boot microservices, implementing RESTful APIs and GraphQL endpoints to integrate with internal systems and third-party services, reducing data retrieval times and enhancing application performance. I built modern, responsive front-end interfaces using React and Angular, leveraging Redux and NgRx for state management, to create seamless and user-friendly experiences. On the infrastructure side, I containerized applications with Docker and deployed them on Kubernetes clusters, while implementing CI/CD pipelines with Jenkins and GitHub Actions to streamline automated builds, tests, and deployments. My work also involved managing both SQL (MySQL, PostgreSQL) and NoSQL (MongoDB, Cassandra) databases, optimizing queries, and designing scalable schemas for high-traffic enterprise applications. I ensured secure access control through OAuth2 and JWT-based authentication, while following enterprise security and compliance standards. Additionally, I migrated legacy monolithic Java applications to cloud-ready microservices on AWS, leveraging EC2, S3, Lambda, and RDS to improve scalability, uptime, and maintainability. Working in Agile/Scrum teams, I collaborated across disciplines to deliver reliable, production-ready software, conducting thorough unit and integration testing using JUnit, Mockito, and Selenium. ## Education ### Master of Science - MS in Computer Science University of Bridgeport Jan 2022 – Jan 2024 ### Bachelor's in Computer Science GITAM Deemed University ## Contact & Social - LinkedIn: https://linkedin.com/in/harshavardhan54 --- Source: https://flows.cv/harshavardhan JSON Resume: https://flows.cv/harshavardhan/resume.json Last updated: 2026-03-22
