Highlights:
- Teaching Python programming and data analysis (pandas, matplotlib, NumPy) to 100+ undergraduate students per semester at QUT, emphasising clean code, reproducibility, and industry-standard practices.
- Architected and delivered RESTful microservices with OAuth2 and JWT authentications, dependency injection, and cloud-native deployment patterns in enterprise production environments
- Developed and shipped full-stack Java/Spring Boot applications for enterprise fintech projects, contributing to a increase in merchant retention through improved lending and transactional workflows.
- Built a full IoT intrusion detection system spanning sensor, edge, and cloud tiers with MQTT-based data pipelines to AWS as part of Masters Project
- Led a cross-functional team of 5 to design and benchmark 3 blockchain-based authentication and authorisation protocols (certificate-based, token-based, and attribute-based) for enterprise stakeholder use cases on Hyperledger Fabric. Built event-driven proof-of-concept applications in JavaScript (Express) and Java (Spring Boot) integrated with Hyperledger Fabric chaincode, demonstrating sub-second transaction verification for RBAC workflows.
- Led a 24-week Full Stack Software Engineering immersive course twice for over 40+ career-transitioning students, designing the end-to-end curriculum covering HTML/CSS, JavaScript, React, Node.js, Python, Django, Flask, PostgreSQL, MongoDB, and Git workflows
