David works across backend, frontend, AI, and infrastructure, with experience taking projects to production and supporting real user adoption\. His strengths include interpreting complex or unclear data schemas, developing backend APIs and frontend workflows, automating infrastructure with Terraform and Jenkins, and working directly with stakeholders to clarify requirements and business needs\. At Manulife, David developed an AI analytics agent for lead ranking and recommendations and built evaluation frameworks for agent\-compromise accuracy and security\-measure effectiveness\. He also built a multi\-agent security platform that simulated prompt\-injection and data\-exfiltration attacks across more than 2,500 agents, deploying and managing those agents with vLLM and QAN infrastructure\. David approaches difficult technical work through research, implementation\-based hypothesis testing, iterative experimentation, and metric validation\. When systems or metrics are flawed, he is prepared to rework the architecture from scratch\. His prior experience includes cybersecurity work at Sun Life and software development at MH Cardiology Diagnostic Centre\. ## Highlights - Current Software Engineer Intern at Manulife, with experience across backend, frontend, AI, and infrastructure\. - Developed an AI analytics agent for lead ranking and recommendations\. - Built evaluation frameworks to verify agent\-compromise accuracy and security\-measure effectiveness\. - Built a multi\-agent security platform that simulated prompt\-injection and data\-exfiltration attacks across more than 2,500 agents\. - Deployed and managed 2,500\+ agents using vLLM and QAN infrastructure\. - Automated infrastructure using Terraform and Jenkins\. - Built frontend workflows and developed backend APIs\. - Shipped projects to production with real user adoption\. - Interpreted complex data schemas and unclear datasets to support technical delivery\. - Worked directly with stakeholders to clarify requirements and understand business needs\. - Applied academic\-paper research, implementation\-based hypothesis testing, and metric validation to technical work\. - Reworked architecture when iterative experimentation and data showed that metrics or systems were flawed\. - Previously served as a Cybersecurity Intern at Sun Life\. - Previously served as a Software Developer at MH Cardiology Diagnostic Centre\. - Pursuing a Bachelor's Degree in Computer Science, Combinatorics & Optimization at the University of Waterloo\. - Earned a High School Diploma from University of Toronto Schools\. ## Experience - **Software Engineer Intern at Manulife** (2026\-04\-01–present) - **Cybersecurity Intern at Sun Life** (2025\-07\-01–2025\-08\-01) - **Software Developer at MH Cardiology Diagnostic Centre** (2023\-06\-01–2024\-09\-01) ## Education - High School Diploma — University of Toronto Schools (2019\-01\-01–2025\-01\-01) - Bachelor's Degree, Computer Science, Combinatorics & Optimization — University of Waterloo (2025\-09\-01) ## FAQ ### What does David do now?
