Selected projects

Three of these have full write-ups — the pipeline I built at Stratpoint, and two systems I built on my own hardware because I wanted to find out where they break.

01Case studies

Personal project · live, in use

Nomi

An installable study app, named after its companion, that turns a student's own notes into flashcards and quizzes that cite the page every answer came from, and grades written answers against a rubric. Nomi, an animated owl, chats, answers questions about your own progress without an AI call, and on one tap can build a study set from pasted notes or write a reviewer on a topic. Built for real users on free tiers.

Movie Analytics Warehouse

An end-to-end ELT pipeline that turns three messy source files into a 20-model dimensional star schema, built for exactly one reader: a specialty-insurance underwriter deciding what premium to quote on a film.

Personal project

Personal AI OS

A model-agnostic personal agent system running entirely on a consumer GPU — no cloud provider anywhere in the codebase — with a purpose-built evaluation harness, a protected holdout split, and 69 architecture decision records including the ones that killed my own hypotheses.

Personal project · shipped to external testers

Nod

A Windows overlay that listens for a wake word, answers out loud in a locally-synthesised Philippine-English voice, and keeps a rolling summary of the meeting you're in — with microphone and speaker audio kept structurally incapable of reaching the same code path.

Full-stack project

AI-Powered Volleyball Gesture System

A gesture recognition backend built on YOLO, MediaPipe and Keras, wired through FastAPI and WebSockets into a Next.js frontend so a referee's hand signal updates every connected scoreboard instantly.

Machine learning project

NLP Resume Classifier

A Flask app that parses an uploaded resume, extracts skills with spaCy NER, and classifies it across 25 job categories using a linear SVM over TF-IDF features — returning structured JSON and a skill breakdown in around 165ms per document.

Undergraduate thesis

Autonomous RC Car Navigation

Undergraduate thesis: a real-time YOLOv8n and ROS2 obstacle-detection pipeline with Kalman filtering and ORB-SLAM3, achieving 0.1m distance error at 10 FPS on constrained hardware.
