🚀 Built & Deployed a Scalable Cloud-Based Dynamic Website! Designed a modern, responsive website using HTML, CSS, Node.js, and Express, then deployed it seamlessly on Render with GitHub CI/CD. ⚡ Delivers fast, reliable content with cloud scalability and a sleek UI powered by glassmorphism.

Cloud-Hosted Dynamic Website

Designed and deployed a containerized Jenkins CI/CD pipeline on AWS Cloud, enabling automated build, test, and deployment workflows for scalable applications. Implemented Docker and Kubernetes for containerization, AWS EC2 and EKS for orchestration, and IAM roles & security groups for access control. Integrated GitHub, SonarQube, and Terraform to enhance version control, code quality, and infrastructure as code (IaC). Optimized pipeline performance with auto-scaling and cloud-native services, ensuring seamless and efficient DevOps automation.

Develop containerized JenKins pipeline on AWS

The project addressed critical challenges like data security, network reliability, and scalability by integrating advanced technologies such as VLAN segmentation, OSPF routing, Cisco ASA firewalls, and Wi-Fi 6. It not only honed my skills in network design, cybersecurity, and system integration but also underscored the importance of future-ready infrastructure in transforming healthcare delivery. The scalable blueprint we developed serves as a replicable model for hospitals embracing digitalization. Key Responsibilities: 1. Designed a hierarchical network (Core, Distribution, Access) for EMRs, telemedicine, and IoT integration. 2. Implemented security measures like encryption, ACLs, and port security for HIPAA compliance. 3. Tested network reliability and performance using Cisco Packet Tracer. 4. Analyzed costs and documented impacts, enhancing patient care and telehealth access.

Hospital Management Networks System

Developed ICS-RedSim, a SCADA and Industrial Control System (ICS) Cybersecurity Simulation Framework to demonstrate and analyze cyberattacks on critical industrial infrastructure in a safe and controlled environment. Simulated industrial communication processes, attack scenarios, and threat detection workflows to assess security risks and vulnerabilities within ICS environments. Designed to support cybersecurity awareness, threat analysis, security assessments, and defensive strategy evaluation for industrial systems.

ICS-RedSim: SCADA & ICS Attack Simulation Fra

• Built a fully virtualized ICS/SCADA cybersecurity lab simulating a real industrial plant environment using OpenPLC and FUXA — enabling safe, repeatable attack simulation without physical industrial hardware. • Deployed Suricata IDS and Wazuh SIEM to monitor Modbus TCP traffic in real time, detecting attack scenarios including OT network scanning, unauthorized PLC command injection, sensor spoofing, and traffic anomalies. • Conducted baseline network traffic analysis using Wireshark and established detection rules to identify deviations in industrial control communications — demonstrating practical threat detection in an OT/IT converged environment. • Simulated attacker behavior from a Kali Linux host across a segmented VMware network, producing actionable findings on ICS protocol vulnerabilities and intrusion detection gaps in critical infrastructure environments.
