What I build.

I'm a Statistics & Data Science student at UCLA finishing my B.S. this June, selected for the Startup UCLA Summer Accelerator 2026, then heading to the University of Pennsylvania for an M.S.E. in Systems Engineering.

The question I care about in AI is not whether a model can generate something impressive. It is whether an agent can understand intent, act across modalities, and stay under grounded control when the work actually matters.

That shows up across my work: grounded generation in FishCapsule, deterministic audio-to-visual systems in SpiroMint, and enterprise ETL pipelines at TTI where messy systems had to become dependable enough to drive operational decisions.

I'm now building as Co-Founder & CTO of a stealth AI startup focused on multimodal agents.

FishCapsule
FishCapsule is a study system built around controlled generation rather than free-form answers. It ingests syllabi, maps courses, selects slides, and keeps every response grounded in the user's actual materials.

The core pipeline combines schema-first generation with Zod contracts, slide-grounded RAG, hash-based caching, and a validation-and-repair layer. That reduced invalid outputs by 70%, kept citation coverage at 99%, and made the system more trustworthy in practice.

TTI PLM Analytics
Built multi-source ETL systems across Teamcenter and OpenLM under enterprise constraints, where the data was messy, operationally important, and tied to recurring reporting needs.

The pipeline covered 6.18M+ usage logs and 14,624 user records, surfaced 15% underutilized licenses, projected $34K annual savings, and automated reporting that saved 38+ hours per month.

SpiroMint turns audio signals into deterministic parameter sets and then into parametric animations using multi-rotor spirograph curves. The chain from signal → parameters → output is reproducible from audio metadata, making provenance inspection possible before minting via IPFS.

↑ Use the controls to inspect the pipeline. Each parameter set represents an explicit stage in how signal drives output.

Music-Driven Generative Research
Undergraduate research with Prof. Jiayin Lu focused on turning audio features into interpretable geometry. Beats, RMS, spectral centroid, and Mel-band peaks are mapped into parametric curves as a structured module for UCLA's Math–Code–Art initiative.

Built an end-to-end data → geometry → pixels → video pipeline using NumPy, PIL RGBA compositing, and FFmpeg.

Skin Cancer Classification
A smaller benchmark-style project focused on disciplined model evaluation on 50K dermatology rows. Unified preprocessing and 5-fold comparison across Logistic Regression, Random Forest, and XGBoost.

Final ridge-regularized logistic model scored 0.607 AUC and ranked 7th among ~170 students.

How the systems thinking deepened.
Jul – Aug 2025
Techtronic Industries · First encounter with messy production systems
Worked across Teamcenter and OpenLM, built ETL around 6.18M rows, and learned that real operational value depends on systems staying reliable under imperfect data.
Sep 2025
Undergraduate Research · Representation became a systems question
At UCLA's Math–Code–Art initiative, I focused on turning signals into interpretable structure — a shift toward controllability, not just output novelty.

SpiroMint · Public proof of deterministic generation
3rd place at AI Best Coast with an audio → parameters → output pipeline where provenance could be inspected and reproduced rather than treated as a black box.

FishCapsule · Trust moved to the center of the product
Showcased at PIC Spotlight with a schema-first, grounded RAG system built around validation, repair, and citation coverage instead of demo-only generation.
