My work spans Android, Firebase, web development, product engineering, debugging, and performance. I also teach IT, which keeps technical communication, examples, and real user problems close to the way I build.
These projects show different parts of how I design, implement, debug, harden, and explain software.
A browser-based Android learning studio for writing Java and XML, running beginner app flows, saving projects, and sharing work without requiring a full Android Studio setup.
An instructor workspace built around attendance, records, students, roster imports, submissions, notes, absenteeism follow-up, and the classroom workflows I deal with directly.
A local-first media recall system using OCR, visual labels, object detection, and embeddings to search images by what appears inside them.
A mobile point-of-sale and inventory system organized around checkout, products, receipts, GCash QR, stock, and reporting.
I am early in my professional career, so this section stays specific about the work rather than inflating job titles.
Teach IT subjects, structure technical lessons, create examples, guide debugging, and help students understand programming and system concepts at different levels of prior knowledge.
Own product direction, interface decisions, Android and web implementation, testing, release preparation, case studies, and direct project communication across Natsu Labs products.
Accepted project-based mobile development work and contributed Android and product-system experience in a practical client-development setting.
The list stays tied to work I can demonstrate in the portfolio.
Java, XML UI, Room, MediaStore, widgets, lifecycle, background work, storage, phone/tablet layouts.
Authentication, Firestore, Realtime Database, Storage, Cloud Functions, FCM, offline and conflict-aware flows.
Semantic HTML, responsive CSS, JavaScript, accessibility, SEO metadata, Firebase Hosting, performance-minded implementation.
Crash analysis, regression repair, state recovery, data-loss prevention, validation, release checks, performance investigation.
User flows, information hierarchy, responsive interfaces, failure states, onboarding, iterative product decisions.
Requirements breakdown, technical explanation, documentation, concrete examples, debugging guidance, handoff communication.
Certificates stay available for verification, but the engineering work above is the primary evidence.
The résumé is designed for quick review. The portfolio carries the deeper project context and engineering evidence.
