I turn ideas into systems.
Sometimes they even work on the first try.

Software, data, and systems.

I'm currently studying Data Science at UNSW, building projects at the intersection of software, AI, and real-world problem solving.

From LLM-based systems to workflow automation tools, I focus on creating things that are not only functional, but genuinely useful.

Projects

AI Meeting Transcription & Summarization System

Built a full-stack meeting workflow that transforms raw audio into structured minutes, reducing manual note-taking effort by ~50% for student society operations.

Problem

Manual meeting notes were inconsistent, time-consuming, and difficult to standardize across student society operations.

Solution

Developed a full-stack pipeline that converts meeting audio into structured summaries with agenda, key decisions, action items.

Multi-Agent Debate System for Misinformation Detection

A research project exploring how latent space disagreement between debating LLM agents relates to prediction errors in misinformation detection.

Problem

Multi-agent debate can improve reasoning, but incorrect predictions are still hard to detect before deployment.

Solution

Measured disagreement in agents’ final layer during debate and analyzed its relationship with final prediction errors.

About Me

Hey, I'm Devin

I build things, solve problems, meet people, stay active and repeat.

Profile photo

Who I am

Software engineer by habit, data scientist by training, and permanently curious by default.

Beyond the keyboard

Outside of code, I spend a lot of time in the gym, play basketball, baseball, tennis, and swim whenever I can.

I also enjoy building communities, which explains how I somehow ended up running career events for 500+ students.

Things I probably spend too much time on

  • Convincing myself leg day is optional
  • Rearranging my gym schedule like it’s a production deployment
  • Believing “just one quick fix” will only take five minutes

From organizing events to building communities

  • Planned and executed 15+ career events, from networking to industry talks and resume workshops
  • Liaised with 20+ companies and alumni to build meaningful opportunities for students

From events to systems

  • Managed internal operations and cross department coordination across a 250+ subcommittee member organization
  • Supported 150+ events annually by standardizing workflows, documentation and communication

What I’ve learned

Leadership isn't about being the loudest person in the room. It's about creating the structure, trust and environment for others to do their best work.
