01 About
Curious by nature.
Detail-driven by habit.
I’m Hanz — a web developer based in the Philippines who enjoys the whole journey of a product: the first sketch, the first line of code, and the moment it finally feels right in someone’s hands.
Over the past 3+ years I’ve built responsive websites, full-stack applications, and the APIs that power them. My background in Computer Science gives me a strong foundation in algorithms, databases, and software design, while my day-to-day work keeps me close to the browser — performance, accessibility, and all the small details users feel but rarely notice.
I care about writing code that the next developer can read, interfaces that work on a five-year-old phone, and shipping on time without cutting the corners that matter. When I’m not building, I’m usually exploring new tools, contributing to side projects, or making something unnecessarily animated.
-
Performance first
Lean pages, optimised assets, and fast APIs — because speed is a feature.
-
Built to be accessible
Semantic markup, keyboard support, and contrast that meets WCAG guidance.
-
Easy to maintain
Clear structure, sensible naming, and documentation the team can actually use.
02 Skills
A well-rounded
toolkit.
From the first HTML tag to the database query behind it — here’s what I work with. I pick tools for the problem, not the hype.
Backend
APIs and server-side logic designed to be secure, predictable, and easy to extend.
Data & Cloud
Structured data, sensible schemas, and deployments that stay up when traffic arrives.
Tools & Workflow
The everyday tooling that keeps work organised, reviewable, and repeatable.

03 Selected work
Things I’ve
designed & built.
A mix of shipped apps, experiments, and interfaces. Each one was built end to end — and most are public, with source and tests on GitHub.
Featured project
2024 — 2025
Z-Learn
Full-stack e-learning platform
A complete classroom platform for educators and students: subjects, lessons, quizzes, submissions, announcements, in-app store, and live video calls. I built the serverless backend and the web experience — from authentication and database schema to file storage and payments.
- Custom JWT auth with email OTP verification
- Cloudflare Worker API on Neon PostgreSQL
- R2 storage, PayPal payments & Agora video
- Role-based flows for students, educators & admins
Request case study
Source available on request
VisualAlgo
An offline algorithm workbench with 62 interactive topics across sorting, searching, graphs, DP and data structures. Every run is precomputed into frames, so play, step, scrub and custom input stay instant — backed by 496 widget tests.
Class Tracker
A semester companion for classes, the weekly schedule, tasks, exams, attendance and notes. Fully offline with Hive storage, Riverpod state, JSON import/export and a one-tap demo dataset.
StudyPredict
An end-to-end ML app that estimates a student’s final maths grade. A scikit-learn pipeline (Random Forest vs Ridge) is served through FastAPI, with a React/TypeScript dashboard for predictions, evaluation and dataset insights.
LocalSearchAI
Private, offline search over PDFs, Word documents, Markdown and notes. TF-IDF ranking, page-level excerpts, exact-phrase mode and duplicate detection — with a React UI, Streamlit fallback and 42 backend tests.
NoteExtract
A local-first study assistant that turns lecture PDFs and notes into extractive summaries, ranked key points, keywords and reading stats. Copy, export to Markdown and save notes — no uploads, no API keys.
HN Digest
A Node/TypeScript cron job that pulls Hacker News top stories, ranks them by points and commits a Markdown digest every morning through GitHub Actions. 42 successful runs and a growing archive of daily editions.
More experiments — ClaimCheck, SpamShield, Guardian Lite, LogSentry and a few automation tools — live on GitHub .
04 Experience & education
Learning by
shipping.
Three years of building real things — for clients, for teams, and for the fun of figuring out how it works.
