• Built full-stack marketplace with service listings, order and user management, reviews, and 3-tier RBAC using Next.js/Redux frontend, microservices architecture with Kafka event streaming, GraphQL Auth API, FastAPI Payment service, Redis caching, and multi-layer validation protecting data integrity
• Engineered GitOps CI/CD with branch-gated workflows, OWASP compliance checks (Trivy, Fscan), GitHub Actions building artifacts to DockerHub, ArgoCD OIDC Dex auth deploying to EKS, and Terraform IaC managing AWS infrastructure with DynamoDB state locking
• Deployed observability stack: Prometheus/Grafana dashboards monitoring API latency and health metrics with Slack alerting, ELK Stack centralizing server and system logs, ArgoCD Grafana integration for production deployment oversight

• Built production-grade marketplaces using Next.js and Redux with secure authentication (NextAuth), dynamic catalogs, cart persistence, and 3-tier RBAC, optimized via SSR/SSG reducing initial load time by 1.8s
• Designed cloud-native microservices including FastAPI Payment service, Kafka event streaming, and multi-layer data validation for protecting data integrity, improving search query performance by 60% through strategic indexing
• Operationalized GitOps-driven delivery by containerizing workloads with Docker, deploying to AWS EKS using ArgoCD with branch-gated CI/CD, OWASP scans, Terraform infrastructure provisioning, and observability using Prometheus, Grafana, ELK, and Slack alerting
