Resume

Welcome to my resume! It consists of two parts. The first part is the free-form narrative of what I do work-wise. The second part is a more traditional list of companies, positions, and projects. The resume is available as .html and .pdf.

Narrative

I am a software systems engineer with a strong foundation in building resilient, scalable applications. I’m passionate about clean, maintainable code and designing systems that solve real-world problems. My experience spans from serverless AWS architectures to cross-platform mobile development, always with a focus on engineering excellence.

I enjoy the challenge of working in multidisciplinary teams, collaborating with experts across different domains to create cohesive solutions. At Convergence Medical, I’ve had the opportunity to work with medical, mechanical, and electrical engineers to build healthcare platforms that meet high engineering standards while maintaining usability for clinical staff.

I’m particularly interested in systems that can handle real-world constraints gracefully. My work on offline-first capabilities with conflict resolution for clinical environments has taught me the importance of designing for reliability in less-than-ideal conditions. When connectivity is lost in an operating theater, the system needs to continue functioning flawlessly.

Security and compliance are foundational to my approach, especially when working with sensitive healthcare data. I’ve implemented HIPAA-compliant authentication systems and integrated healthcare standards like FHIR/HL7 to ensure interoperability with existing hospital systems.

Throughout my career, I’ve maintained a commitment to quality through comprehensive testing strategies. I believe that reliable systems are built on a foundation of thorough unit, integration, and load tests that prevent regressions and ensure performance under stress.

I continue to learn and grow with each project, and I’m excited about the possibilities that lie at the intersection of technology and healthcare.

Convergence Medical

Nov 2024 to Apr 2025
Brisbane, Australia

Software Systems Engineer

Lead design and implementation of an enterprise healthcare platform enabling secure communications between V01 surgical arthroscopic robots and clinical staff across multiple devices.

  • Architected multi-layered system with discrete components including client layer, API/authentication layer, clinical services, and security/compliance layers, creating a highly scalable and maintainable codebase.
  • Engineered secure authentication system with enterprise-managed registration using AWS Cognito and custom IAM roles, enhancing HIPAA compliance and reducing security vulnerabilities.
  • Developed offline-first capabilities with conflict resolution for clinical environments, ensuring consistent application availability even with intermittent connectivity issues in operating theater.
  • Implemented FHIR/HL7 healthcare standards integration using AWS HealthLake, enabling data exchange with existing hospital systems.
  • Built React Native/Expo cross-platform application with secure Peer-to-Peer(P2P) communication between surgical devices and clinician interfaces, substantially reducing surgical procedure setup time.
  • Designed and deployed comprehensive serverless backend with Lambda functions, DynamoDB, and AppSync GraphQL, optimizing infrastructure costs compared to monolithic architecture.
  • Collaborated closely with mechanical, medical, electrical engineers and product team to create accessible features that aligned with high engineering standards and best practices.
  • Implemented and maintained unit, integration, and load tests to ensure reliability and performance of Convergence Medical platform, achieving highest coverage and preventing regressions across multiple feature releases.

Brisbane, Australia

Undergraduate Research Assistant

Developed autonomous system security frameworks for multi-robot environments, focusing on attack detection and mitigation strategies.

  • Designed and implemented DOS attack modeling system for multi-robot testbeds using Python and Kalman filter algorithms.
  • Enhanced attack detection threshold through optimized estimation algorithms validated on Robotarium testing platform.
  • Conducted thesis research on cyber threat modeling techniques for multi-robot teams with focus on physical layer security.

IO Stream

Jun 2022 to Dec 2022
HCM City, Vietnam

Developer Intern

  • Developed C++ 11 library for image processing with the deep understanding of generics type implementation.
  • Maintained RESTful APIs using Node.js and TypeScript for company web application.

Projects

SpamOverflow

2024
University of Queensland

Developed a scalable email filtering service using a microservices architecture on AWS, capable of processing up to 10,000 emails per minute. Implemented infrastructure as code using Terraform, enabling consistent and repeatable deployments.

  • Implemented MySQL database normalization techniques and optimized SQL queries to handle high-volume email metadata storage and retrieval.
  • Leveraged AWS Lambda for serverless email processing, reducing operational costs compared to traditional EC2 instances.
  • Integrated AWS SQS for asynchronous processing, ensuring zero message loss during traffic spikes of up to 20,000 requests per minute.
  • Utilized AWS ECS with Docker for containerized microservices, improving scalability and reducing deployment time from hours to minutes.
