Fly my drone from here

Move the sticks and the drone follows. Scroll and it comes down the page with you. Each move builds the same 7-byte packet my transmitter sends to Project Horizon, checksum included.

What I can do for you

Five things, each backed by something I built.

  1. AI agents people can trust

    Agents that read, decide and act, with a person approving before anything goes out. Backed by Google AI Essentials, Anthropic's AI Fluency and Claude Code in Action, AWS Generative AI and Microsoft Azure AI Fundamentals.

  2. Shipping for real users

    Since Grade 9 I've worked at Canoegy, my dad's IT company: web development, cloud on AWS and Azure, and security for real clients. My school runs on tools I wrote: its announcements, event planning, elections and suggestion box.

  3. Systems that don't break quietly

    Checksums, failsafes, run logs and diagnostics. When something fails, it fails safe and says why.

  4. Hardware and the code that runs it

    A drone flown on my own controller and radio protocol. You can fly it at the top of this page.

  5. Mobile apps

    Android apps in Java and with Capacitor, with sign-in, on-device storage and AI features.

Selected work

Project Horizon

Hardware, 2026
  1. Pilot controllerAn Arduino Nano reads two sticks and two switches and packs them into 7 bytes.
  2. Radio linkOne-way 2.4 GHz at 250 kbps, with a 16-bit CRC and our own checksum.
  3. Drone receiverA second Nano rejects corrupt packets and outputs six PWM channels.
  4. SBUS converterSix PWM channels become one SBUS stream.
  5. Flight controllerBetaflight runs the stabilisation loops and drives four motors.

[PHOTO 3: the custom circuit boards]
1 / 3

A 5-inch FPV quadcopter where every link in the control chain is ours, from the hand-soldered controller to the radio protocol.

Problem
Hover a drone without a store-bought radio system. Electrical noise from the motors kept corrupting packets and disarming it mid-test.
What I built
With Algasem Zabarah, for our Grade 12 computer engineering capstone. I wrote the controller firmware that reads the sticks and builds each packet. The link adds an XOR checksum and a failsafe that rides out short dropouts and cuts the throttle after 1.2 seconds.
Stack
Arduino Nano, NRF24L01 radios, ESP32-CAM video with a web heads-up display, Betaflight, custom PCBs from JLCPCB.
Result
A stable, controllable hover on our own controller. The noise disarms are gone.

What I built
An Android app on Capacitor, a web version and a landing page. An Item Finder keeps its history on the device, and an Outfit Visualizer previews outfits with an image model. When the AI analysis fails, you can enter an item by hand.

BasilBot

AI email agent
[SCREENSHOT 1: an email summary in Telegram]

1 / 3

An email agent you run from Telegram. It reads the inbox, drafts replies, pulls out tasks and waits for a yes before it acts.

Problem
[BASILBOT: THE CLIENT'S PROBLEM]
What I built
BasilBot starts from Olivier Loverde's open-source gmail-agent. On top of it I added a provider architecture, approval gates and a sender policy.
Stack
Node.js, Gmail API, Telegram Bot API, OpenAI models, SQLite.
Result
It already runs a client's inbox. [BASILBOT: ONE NUMBER, SUCH AS EMAILS HANDLED A WEEK]

How I work

I don't stop at "it works." I keep going until it's reliable, then I make it simpler.

  1. I chase bugs to the root

    Project Horizon kept disarming mid-test. The cause was electrical noise from the motors corrupting radio packets. I added a checksum so bad packets get thrown out, a failsafe that rides out short dropouts, and moved the signal wire away from the motor wiring. It hovers now.

  2. I fix what I inherit

    The school's announcement script couldn't run on a timer, and a typo in a date could quietly delete an announcement. I rebuilt it: every run starts clean, dates compare in one time zone, and every run is logged.

  3. People stay in charge of the AI

    BasilBot drafts the replies, but nothing goes out until someone taps yes. Speed from the agent, judgment from the person.

Since Grade 9 I've done client work alongside a 97% average, a job as a lifeguard and swim instructor, and co-leading a student council of 20. I'm used to shipping with a full plate.

Want to know me as a person?

The lifeguard, the student council, the three languages and the beach home I'm saving for. It's all on the other side.
