My Experience

Key Achievements:

• Developed and maintained Node.js/TypeScript backend services powering Auth0's Enterprise Federations platform for SAML 2.0 and OIDC-based SSO
• Implemented and extended federated authentication flows (SAML SP/IdP-initiated SSO, OIDC authorization code flow, OAuth 2.0 token exchange) with protocol spec compliance and security hardening
• Built and enhanced Enterprise Connection RESTful APIs supporting full connection lifecycle: create, update, certificate rotation, claim mapping, and attribute transformation
• Contributed to Auth0's multi-tenant distributed authentication infrastructure reliability through on-call rotations and production incident response
• Integrated AI tooling into engineering workflows to accelerate development cycles and improve code quality

Key Achievements:

• Architected and maintained globally distributed GraphQL APIs using Apollo Federation across microservice subgraphs on Azure Kubernetes Service (AKS) serving millions of smart-home device users
• Designed TypeScript/NestJS RESTful and GraphQL backend services with ORM-based data layers and query optimization, reducing API response latency
• Built React and Next.js frontend features with full TypeScript coverage, integrating design system components and accessible, responsive UIs
• Implemented authentication and authorization layers (JWT, OAuth 2.0, RBAC) integrated with Auth0 for secure identity management
• Designed disaster recovery and failover strategies for distributed cloud systems, ensuring high availability across multi-region deployments
• Built event-driven pipelines for real-time data processing and third-party service integrations using async patterns and message brokers
• Integrated ELK stack for centralized logging; established unit and E2E test suites with Jest and enforced code quality standards
• Mentored junior and mid-level engineers; led architecture discussions and cross-functional stakeholder reviews

Key Achievements:

• Designed RESTful (API Gateway) and GraphQL (AppSync) APIs in TypeScript and Python on AWS serving a global student-facing platform
• Architected and deployed serverless Lambda functions via AWS SAM, enabling scalable and cost-efficient backend event processing
• Led development of a multi-region internationalized React/TypeScript web application with i18n support for 10+ locales
• Standardized environment provisioning with AWS CloudFormation (IaC), eliminating configuration drift across dev, staging, and production
• Modernized legacy PHP and Ruby services into Python/Node.js microservices, improving system reliability and developer maintainability

Key Achievements:

• Served as lead architect for a greenfield social media platform on AWS—designed full API, backend service topology, data models, and infrastructure from scratch
• Designed event-driven, high-throughput real-time interaction systems using message queues and async Node.js services to support large-scale social platform traffic
• Automated infrastructure provisioning with AWS CloudFormation IaC and established deployment pipelines for repeatable, zero-downtime releases
• Led engineering hiring, contributed to technical roadmap planning, and managed payment processing integrations and vendor relationships

Key Achievements:

• Built and published shared Python/TypeScript libraries consumed across multiple backend services, standardizing common tooling and reducing duplicated logic
• Designed Apollo Federated GraphQL APIs consolidating data from distributed microservices into a unified graph for client applications
• Containerized backend services with Docker and automated CI/CD via GitHub Actions and AWS CodeArtifact
• Provided architecture guidance on cloud infrastructure scaling

Key Achievements:

• Designed and built multiple full-stack applications—Python/Django REST and GraphQL backends with React/TypeScript frontends—deployed as containerized microservices
• Built a real-time ETL pipeline using GraphQL, RabbitMQ, Django, Celery, and PostgreSQL for high-throughput solution test automation
• Developed a unified device automation GraphQL API (Django, RabbitMQ, Celery, MySQL) orchestrating test infrastructure across distributed lab environments
• Built a resource/asset management system with Node.js/Apollo GraphQL API and TypeScript frontend; maintained PyPi, DHCP, FTP, and Nginx containerized services
• Deployed and maintained CI/CD pipeline (Ansible, GitHub, Jenkins); implemented Grafana and Zabbix observability; administered Ubuntu/CentOS Linux systems

Key Achievements:

• Led a team of 6–8 engineers building hybrid network automation solutions using Python, Ansible, VMware, and Docker
• Partnered with architects and tech leads to design complex distributed automation integrations
• Drove event-driven architecture adoption and Grafana/Zabbix observability implementation

Key Achievements:

• Architected a globally distributed network automation platform using microservice patterns, a Python async processing backend, and a real-time analytics dashboard (Django, Celery, RabbitMQ, MySQL)
• Developed FastAPI and Django REST APIs to integrate cross-team systems
• Containerized services with Docker; managed ESXi virtualization and Ubuntu/CentOS Linux administration

Key Achievements:

• Managed and mentored a team of 6–8 engineers
• Handled high-priority customer IP network escalations
• Developed Python automation scripts for backup and scheduling

Key Achievements:

• Deployed and migrated customer network solutions onsite
• Provided expert IP networking support in a TAC environment
• Delivered remote and on-site training

Key Achievements:

• Recreated customer network topologies in lab environments to support escalation diagnosis and knowledge transfer
