Presentation
I work across the full stack of a data product:
Machine Learning & Deep Learning — PyTorch, TensorFlow, scikit-learn. Model design, training, optimization, and differential privacy (DP-SGD, Opacus). Published at peer-reviewed venues including AsiaCCS.
Web Development — Next.js 14, React, NestJS, Node.js, TypeScript. REST APIs, authentication, real-time features (LiveKit), and full deployment on AWS with Terraform, ALB/HTTPS, S3, and Route 53.
Databases — PostgreSQL, Redis. Schema design, query optimization, migrations, caching strategies.
Desktop Applications — Python and C# desktop tools for data processing, automation, and internal workflows.
Most recently I designed and built a complete online education platform end to end: backend, frontend, database, cloud infrastructure, and deployment.
I teach at university level, so I explain my decisions clearly and leave you with code and documentation you can actually maintain. I'd rather tell you a task is out of scope than take it and underdeliver.
