Blockchain is a distributed ledger technology that allows for transparent and secure transactions within a network. Each node holds a complete record, and any changes to the ledger are validated through consensus, eliminating the need for intermediaries in processes such as cross-border payments. This results in direct and immediate transfers without the risk of manipulation. Blockchain's benefits include reduced costs by removing middlemen, quicker settlement times, and enhanced security with encrypted transaction details. The technology also reduces standardization challenges and offers increased payment transparency since all parties involved have access to the ledger's information.

In 2020, I engaged in the esteemed InfraMind competition hosted by TCS, where I presented an innovative project concept focused on utilizing blockchain technology for financial transactions. My proposal detailed a sophisticated model for secure and efficient money transfers leveraging the inherent strengths of blockchain, promising to revolutionize the domain of digital payments.

Galaxy Studios' SQL database system is designed to manage various aspects of film production, including talent management, production tracking, awards, and operational efficiency. The database follows an Entity-Relationship (ER) model, normalized to Third Normal Form (3NF) to ensure data integrity and minimize redundancy. Core entities such as Movies, Actors, Directors, Crew, Awards, and Reviews are structured with primary and foreign keys to maintain relational integrity. SQL implementation includes stored procedures and triggers for automation, while complex queries retrieve insights like top revenue-generating movies and award-winning films. Indexing and query optimization enhance performance, ensuring efficient data retrieval.

To maintain security, user roles (e.g., Admin, Reviewer) are defined with controlled access, preventing unauthorized modifications. A comprehensive backup strategy includes full weekly backups, daily differential backups, and hourly transaction log backups, stored securely on-site and in the cloud. Validation measures, such as backup and restore tests, ensure data integrity. The final deliverables include a fully implemented SQL database, along with documentation covering ER diagrams, database schema, queries, and procedures.

As part of a hands-on cybersecurity generalist simulation for Commonwealth Bank, I engaged in a series of real-world cybersecurity tasks focused on fraud detection, security incident response, and penetration testing. I developed data-driven fraud detection strategies by leveraging Splunk dashboards to analyze historical customer data, uncover anomalies, and enhance investigative insights. Additionally, I strengthened my incident response capabilities by executing protocols for threat containment, mitigation, and recovery while coordinating with relevant teams to ensure swift resolution of security breaches.

Furthermore, I gained practical exposure to penetration testing by assessing web application vulnerabilities, identifying security gaps, and recommending remediation strategies to fortify cyber defenses. I also contributed to security awareness initiatives by designing informative infographics promoting secure password management in alignment with Australian Cyber Security Centre (ACSC) best practices. This experience enhanced my technical proficiency in threat intelligence, security analytics, and proactive defense mechanisms, reinforcing my ability to combat evolving cyber threats in enterprise environments.

In this cybersecurity job simulation, I worked as an Analyst on Mastercard’s Security Awareness Team, focusing on threat identification, risk mitigation, and employee security training. I played a key role in detecting and analyzing phishing threats, assessing their impact on organizational security, and reporting them to relevant stakeholders for mitigation. Using threat intelligence methodologies, I evaluated phishing tactics, attack vectors, and user susceptibility to enhance the company's defense posture.

Additionally, I conducted a security awareness gap analysis across various business units, identifying teams with higher exposure to cyber threats. Based on my findings, I designed and implemented targeted security training programs, equipping employees with best practices for threat recognition, secure handling of sensitive data, and incident response protocols. This project strengthened my expertise in social engineering defense strategies, cybersecurity education, and proactive risk management, reinforcing the importance of a human-centric approach in enterprise security.
