GitHub: https://github.com/waynel LinkedIn: https://www.linkedin.com/in/wwwayneliu/ Note: For the past 12 months, I've been heavily focused on AI Engineering and AI-augmented Software Engineering - building features that use large language models (data entry automation, retrieval augmented generation and text-to-SQL chatbots) and experimenting with AI tools to improve my engineering workflow. I've been working as a software engineer for 10+ years that has been mainly focused on web application development and some systems development, in NYC and Boston. Have had full-time roles at 4 startups and 1 corporation. I come from a strong computer science background, having graduated from Carnegie Mellon University. My experience lies both in computer science fundamentals and shipping projects end-to-end as a full stack generalist - frontend, backend, data, and SRE. Having worked at startups, I've learned to be versatile, doing some minor product and project management as well. In addition, I've launched 3 full stack side projects. With 5 years of experience mentoring other engineers, I've conducted 50+ technical interviews and have been interviewed 20+ times. I enjoy helping others - it's fulfilling to help others level up while also helping my own continuous learning! Some potential areas I can help with: - brushing up on computer science fundamentals - preparing for software engineering interviews (data structures and algorithms coding problems, system design, behavioral) - pair programming on a project, recommending best practices for frontend, backend, data, and SRE - code review - debugging - testing - resume review - career strategy consultation
