Tonie C. — Developer

01 About

Who I am

What I build, how I learn, and where I'm heading.

I'm Tonie, a developer from the Philippines who builds software across different layers of a system — from interfaces and APIs to hardware, automation, and embedded projects.

Most of what I know comes from building things myself. I usually start with a rough idea, turn it into something functional, then keep breaking, fixing, and improving it until I understand the problem better.

I'm currently looking for internships, junior opportunities, freelance work, and collaborations where I can work on real projects, solve practical problems, and keep getting better at building software.

BUILD

Maintainable systems — clear code and sensible structure matter more than clever solutions.

WORK

Across layers — moving between UI, servers, automation, and hardware is part of the work.

LEARN

By building — working software teaches more than following another tutorial.

COLLAB

With other developers — contributing to existing projects while learning how other people solve problems.

FOCUS

Useful software — building things that solve an actual problem instead of existing just to demonstrate a technology.

02 Skills

What I work with

Technologies I use to build, connect, and ship things.

Frontend

HTML & CSS JavaScript TypeScript React Tailwind CSS Next.js Framer Motion

Where I build interfaces — from simple pages to full applications, including this portfolio.

Backend

Node.js Express REST APIs Python AsyncIO MongoDB PostgreSQL SQLite Redis Prisma WebSockets

Building APIs, handling asynchronous workloads, working with databases, and connecting services together.

Embedded

ESP32 Arduino C / C++ I2C / SPI BLE / Wi-Fi MQTT Sensor Integration

Connecting hardware, sensors, and software — usually through microcontrollers and small IoT systems.

Tooling

Git & GitHub Linux NPM packages PyPI packages Discord API Docker CI/CD

The tools I use to build, test, publish, deploy, and maintain projects.

03 Projects

What I've built

Work that demonstrates real design decisions, not just output.

Featured Project

Email Studio

A self-hosted developer email IDE. Write HTML/CSS in a CodeMirror editor, preview responsive layouts, convert to email-safe HTML, and send via Gmail OAuth or any SMTP provider — all from the browser.

NODE.JS EXPRESS SQLITE CODEMIRROR OAUTH 2.0

GitHub

Architecture Overview

Email conversion pipeline sanitizes markup, inlines CSS, converts flex layouts to tables, and hardens the output for email clients.
Compatibility analysis checks rendered output against Gmail, Outlook, Apple Mail, and Yahoo, with guidance for fixing issues.
Gmail OAuth 2.0 or SMTP credentials are supported for sending, both encrypted at rest — Gmail passwords are never requested or stored.
A visual editor with a property inspector and undo/redo sits alongside the code editor, backed by a sandboxed responsive preview.

Real Use Cases

Newsletter Design Build and preview HTML newsletters without fighting email client quirks.

Transactional Emails Convert clean HTML/CSS into email-safe markup ready to send.

Client Delivery Export a project as a ZIP or single HTML file for handoff.

Compatibility Testing Catch Gmail/Outlook rendering issues before sending to real inboxes.

Featured Project

Uptime Monitor

A self-hosted uptime monitoring application for tracking the availability and performance of web services. Provides continuous health checks, response-time monitoring, uptime history, and incident tracking through a focused operations dashboard.

JAVASCRIPT WEB SOCKETS HTTP MONITORING SELF-HOSTED

GitHub

Architecture Overview

HTTP and HTTPS health checks periodically verify whether configured services are reachable and responding correctly.
Response-time measurements are recorded alongside service status, allowing performance degradation to be distinguished from complete outages.
WebSocket-based updates keep the dashboard synchronized with monitoring activity without requiring constant page refreshes.
A modular frontend separates dashboard, service details, incidents, charts, uptime visualization, and modal interactions into dedicated components.

Real Use Cases

Website Monitoring Continuously check websites and web services for availability and unexpected downtime.

API Monitoring Track HTTP endpoints and identify failed requests or abnormal response times.

Performance Tracking Monitor response times over time to identify services becoming slower before they completely fail.

Incident Tracking Keep a record of service outages and degraded states for later review.

OPEN SOURCE

Featured Project

tflows.py

A lightweight Python framework for building Discord bots and task automation pipelines. Built around a scripting engine that keeps bot logic modular, testable, and separate from Discord's event system.

PYTHON ASYNCIO DISCORD API OPEN SOURCE PYPI

GitHub PyPI Documentation

Architecture Overview

Async-first design built on Python's asyncio — event handlers and tasks run concurrently without blocking.
Scripting engine separates bot commands from Discord plumbing, making individual flows testable in isolation.
Modular loader system lets you add, remove, or reload bot modules at runtime without restarting.
Thin abstraction layer over discord.py — doesn't hide the library, just reduces repetitive wiring.

Real Use Cases

Server Moderation Event-driven auto-moderation rules without custom bot architecture.

Task Automation Scheduled jobs and webhook triggers wired to Discord channels.

Rapid Prototyping Stand up a functional bot in minutes with minimal boilerplate.

Scripting Engine Define flows as plain functions; the framework handles wiring.
