A full-stack DevOps project for a demo radiology worklist application, built with React, Node.js, Express, and MongoDB. The application was first containerized with Docker Compose and then deployed to a real Kubernetes cluster across three VPS instances, including persistent storage, NodePort access, pod self-healing, node drain testing, and cluster visualization with Lens.

• Built a React frontend for viewing, adding, and deleting demo imaging cases
• Built a Node.js and Express backend API connected to MongoDB
• Containerized the frontend, backend, and database with Docker Compose
• Wrote Kubernetes manifests for the frontend, backend, MongoDB, services, and persistent storage
• Deployed the application to a three-node Kubernetes cluster on VPS infrastructure
• Demonstrated Kubernetes self-healing by deleting pods and observing automatic replacement
• Simulated node failure with node drain and verified pod rescheduling
• Used Lens to visually inspect pods, services, logs, and deployments across the cluster

A Jenkins-driven CI pipeline for a Maven Java application, with GitHub triggers, automated tests, SonarQube quality gates, and Nexus artifact publishing on separate AWS EC2 hosts.

• Built a Jenkins pipeline triggered from GitHub changes
• Compiled and tested a Maven Java application automatically
• Integrated SonarQube for code quality checks and quality gate validation
• Published build artifacts to Nexus Repository
• Used separate AWS EC2 instances for Jenkins, SonarQube, and Nexus
• Demonstrated a full CI workflow from code push to artifact storage

A Node.js application demonstrating practical integration with the OpenAI Responses API - covering authenticated requests, parameter tuning, conversation memory, and real-time streaming.

• Built an authenticated client for the OpenAI Responses API
• Sent requests and parsed responses, including token usage and metadata
• Tuned output behavior using temperature and max_output_tokens
• Maintained conversation context across multiple calls using response IDs
• Implemented real-time streaming of model output, token by token
• Secured API credentials using environment variables, excluded from version control

A complete enterprise network designed and implemented in Cisco Packet Tracer and Cisco Modeling Labs, covering routing, switching, security, VPN, and high availability for a fictional medical company with HQ and branch sites.

• Designed a dual-ISP, dual-firewall HQ architecture with full redundancy
• Configured OSPF routing and HSRP gateway redundancy across all VLANs at both sites
• Implemented IPsec site-to-site VPN between HQ and branch office
• Set up VLAN segmentation with 802.1Q trunking across 9 departments
• Deployed WLC-managed wireless network with CAPWAP lightweight APs
• Verified full connectivity - all tests passed across HQ, branch, DMZ, and VPN
