Featured Projects

KLARO — AI-powered Data Intelligence

High

A startup platform that eliminates the gap between raw business data and actionable insight. KLARO applies OCR and AI to extract structured information from documents, spreadsheets, and scanned reports — then surfaces it through clean, interactive dashboards that help operations teams make faster, evidence-backed resource decisions.

structura.ai — AI-powered Synthetic Market Research

High

A research-to-product initiative grounded in a published academic framework on AI-driven customer discovery. structura.ai deploys agentic systems to simulate synthetic market personas, run hypothesis testing, and surface validated insights — cutting early-stage market research from weeks to hours without a single survey.

GUIA — AI-powered CET Guide

High

A consultancy-grade web platform built to transform how students prepare for the College Entrance Test. GUIA analyzes mock exam performance, identifies subject-level weak points, and generates personalized study plans — giving each student a targeted, data-driven path to their target university instead of a one-size-fits-all review.

Other Projects

CareBnB Elderly Care

MVP

A two-sided marketplace that matches seniors and families with vetted freelance caregivers for immediate, on-demand care. Handles caregiver profiles, availability scheduling, and booking flow end-to-end.

Python HTML CSS

Matteo Up Reservation

Build

A table booking system built for Ateneo's Matteo Up café that lets students reserve specific time slots in advance — eliminating queues and giving the venue real-time capacity visibility.

Python HTML CSS JavaScript

Password Library

Build

A locally-hosted credential manager that stores and retrieves passwords from a private encrypted database — built as a lightweight alternative to commercial password managers with zero cloud dependency.

Python HTML CSS

Research Library

Build

A shared web app for research teams to submit, tag, and browse curated research links by topic — replacing scattered bookmark folders with a searchable, collaborative knowledge base.

Python HTML CSS

Universal Translator

Prototype

A proof-of-concept that hooks LLM APIs directly into a Flask translation interface — built to validate how well large language models handle multilingual output compared to dedicated translation services.

Python HTML CSS

PDF Summarizer

Build

Uploads a PDF, extracts its full text, and routes it through an LLM API to return a structured summary — cutting document review time for analysts who process high volumes of reports.

Python

ReAds Report Summarizer

Client

Built for Kythe — classifies incoming reports by topic using LLM APIs and converts raw dataset rows into coherent qualitative narratives, reducing manual write-up time for their analyst team.
