<p>
I'm a Computer Science and Engineering student at the <b>Universitat Autònoma de Barcelona</b>,
currently on academic exchange at <b>UC Santa Cruz</b>. My work sits at the intersection
of applied AI and systems that have to actually work in the field — from an
incident-reporting tool used by emergency departments, to a robot that solves
physical puzzles, to a computer-vision system that scores exercise form from video.
</p>
<p>
I like problems where the hard part isn't the model — it's the <b>pipeline</b> around it:
getting messy real-world input into a shape a system can reason about, and turning
its output into something a person can actually use.
</p>
<p>
Outside of coursework, I'm part of the founding team behind <b>FireForm</b>, a UN-recognized
Digital Public Good now developed through Google Summer of Code.

Public crime-data dashboard for the UCSC Police Department, extended with a

<ul>
<li>Fixed and extended an existing Power BI dashboard — interactive map, live filters</li>
<li>Built the retrieval pipeline: vector search over normalized crime data, answers generated with Gemini</li>
<li>Data pipeline: RIMS → sanitization → Node/Express on Linode → PostgreSQL → Power BI</li>

<h3>Body Posture Analysis System</h3>

A computer-vision system that scores squat and push-up technique from 2D video —
and the story of replacing a fixed rulebook with a model that actually learns
what "correct" looks like.
</p>
<ul>
<li>Dropped a custom pose-estimation model for MediaPipe once training cost proved impractical</li>
<li>Rule-based detector alone scored <b>0% correct reps</b> on real validation video — thresholds were too strict, not the pipeline</li>
<li>Trained a multi-label Random Forest on the same biomechanical metrics, validated with Leave-One-Video-Out</li>
<li>Result: accuracy improved to <b>81–87%</b> per error type; replicated end-to-end for a second exercise</li>

A CNC-style robot that sees a jumbled puzzle, works out the solution, and

<li>Owned the full software stack: computer-vision piece detection and the solving algorithm</li>
<li>Generated the robot's pick-and-place command sequence</li>
