Academic capstone / Full-stack

Museo Bulawan MIS

Best Capstone 2026

I built the scheduling and appointment system: a five-step visitor booking flow, role-based admin dashboards, and real-time slot updates with Socket.IO.

React, Node.js and MySQL connect public appointments with staff schedule management.

Keeping bookings and admin schedules in sync

Visitor reservations and staff updates need to share the same slot availability. I built a five-step booking flow with date and slot validation, MySQL-backed scheduling, and bidirectional Socket.IO updates to keep availability synchronized and prevent double-booking.

Three role-based dashboards support schedule management, capacity limits and visitor check-ins. This connects the public booking journey to the day-to-day work of museum staff.

Testing & quality

Alongside development

I test Android apps and report what I find.

My reports go to Slack, with screenshots for visual issues and screen recordings when needed. Here are examples from my work, summarized without internal conversations.

MLBB Game Guide · Functional testing

Quiz scores reset after signing back in

Reported · October 20, 2026
Issue
The overall score returns to 0 after signing back in, despite existing quiz records and newly saved attempts.
Expected
Recorded quiz scores persist across sign-in sessions.
Retest status
Unresolved in my last report; no later fix or successful retest is recorded.
Reproduction details
Reported behavior, reconstructed from my bug report
  1. Existing quiz recordsSign in with Google and check the overall score with previous attempts present.
  2. Sign out → sign inSave a new attempt, then sign out and sign back in with the same Google account.
  3. Overall score: 0New attempts save, but the score resets again.

Report reconstruction · Not an app screenshot

A separate Personalization data-recreation issue was resolved. That does not establish a fix for quiz-score persistence.

Read sanitized report

MLBB Game Guide · Debugging & unit tests

Debugging the scramble quiz

Partial answers triggered the next question too early. The fix waits until every required letter slot is complete, accounting for symbols and hint-filled positions. AI-assisted Kotlin/JUnit test changes cover scramble-answer completion.

EarnPH · Filter consistency

Checking date filters across two screens

Date formats and end-date boundaries caused inconsistent results, and some Explore filters were not connected. Shared logic aligned both screens.

Developed locally; not yet released.

Content & visual defects

Reported null text in Patch Notes Details and distorted Battle Spells and Items icons.

MLBB Game Guide

Layout & system insets

Reported duplicate headers and content overflowing system padding in an Android LTO reviewer app.

Manual UI testing

Retesting with the teamShared Firebase App Distribution builds and APKs, with requests to recheck reported issues, language switching, text and layout against Figma.

Unit tests with AI assistanceI use AI-generated Kotlin/JUnit tests to check quiz logic and other development changes, alongside manual app testing.

Reviewing AI-assisted changes

I check proposed changes against the existing architecture and intended behavior, correct the scope, request build checks, and personally validate the resulting implementation.

For EarnPH, I reported date-picker behavior and kept the correction scoped to event filters, leaving birthday inputs separate. Codex, Google Antigravity and OpenCode support investigation, planning, code and test preparation.
