Sicheng Ouyang

About

Hi there! I'm Sicheng Ouyang, a Software Engineering student at the University of Waterloo (Sep 2025 - 2030). I like building full stack web apps and exploring practical ML applications. I have experience in backend systems, ML workflows, and product delivery from my own projects and several internships. And I'm passionate about learning from production data and iterating quickly in real environments.

I'm especially interested in bridging robust backend architecture with clean, minimal user experience, and I care a lot about reliability and clear system behavior as products scale.

Experience Highlights

  • Co-founded and built an A-Level study platform on Tencent Cloud, reaching roughly 1,000 daily active users.
  • At Tencent Music, evaluated 10 speech synthesis models across 20+ experiments and improved vocal consistency by 20%.
  • Built a React Native map app with location visualization and optimized trail storage/rendering for better performance.
  • Ran handwriting recognition data experiments to 96% accuracy and deployed a local DeepSeek setup used by 20 researchers.
  • My usual learning loop is: read docs/papers, build a small prototype, evaluate with measurable results or simply just act as a daily user, then iterate quickly.
  • As a builder and operator, I also care about user experience and cost-performance tradeoffs, I do consider that as my top priority when I build a product.

Skills Snapshot

  • Languages: Python, Java, C/C++, JavaScript, TypeScript, HTML/CSS.
  • Frameworks/Tools: FastAPI, Flask, React, React Native, MySQL, Git, WordPress, LaTeX, Node.js.
  • Languages spoken: English (fluent), Mandarin Chinese (native), French (basic).

More About Me

Besides all of the coding, I am also a big fan of going to the gym and play tennis, FPS games are also a fun way for me to relax and connect with friends. I also enjoy traveling and exploring new places, especially if there are good food around!

Note

Thank you for reading all of this! If you've comed this far into the website, maybe try the terminal puzzle I built up on the >_ section, there are three different animations in it and I put many effort in making it.
