Designed a scalable Entity Management Platform with dynamic data modeling, graph-based relationships, and event-driven state transitions — ensuring auditability and traceability across a microservices environment. Designed and owned a high-throughput Order Processing System covering end-to-end lifecycle management (validation, cancellation, rejection, modification), sustaining 200,000+ orders/day in production. Architected and led delivery of an Event Orchestration Platform enabling loosely coupled, asynchronous microservice communication at scale — processing ~1.5M events/day in production. Built traffic replay load testing infrastructure for staging environments, enabling real-traffic simulation to validate performance, scalability, and integration pre-release. Developed a low-latency job routing mechanism using Bloom Filters, reducing redundant API calls and improving pipeline efficiency by ~40%. Led end-to-end design, integration, and launch of multiple production printing workflow automations, streamlining cross-team operational processes — recognized with the Cimpress India Spot Award for ownership and technical initiative. Mentored 4 interns through structured technical guidance, enabling independent contributions to production engineering deliverables. Tech Stack: Node.js, NestJS, Java, Spring Boot, AWS, PostgreSQL, Kafka, SNS, SQS, DynamoDB, New Relic

Engineered high-throughput REST APIs for key manufacturing workflows, sustaining 6,000 RPM at 5.6 ms avg response time — supporting $1.5B+ revenue. Achieved 93% latency reduction via PostgreSQL query optimization and strategic indexing, eliminating production bottlenecks. Integrated Akeyless for secrets management, enabling RFC-compliant, secret-free infrastructure and simplifying key rotation across services. Architected and deployed scalable backend services on AWS, enabling seamless full-stack integration and supporting high-availability production workloads. Built reusable UI components adopted across multiple product surfaces, reducing front-end development time and enforcing design consistency at scale. Automated infrastructure provisioning and deployments using AWS SAM (IaC) and GitLab CI/CD pipelines, achieving reliable, zero-touch web application releases. Tech Stack: NestJS, Java, React.js, Redux, AWS, GraphQL, Sumo Logic, CI/CD, PostgreSQL, AWS SAM
