Shazam
A from-scratch implementation of Shazam's audio fingerprinting algorithm — built in Flutter with a Python preprocessor. Inspired by Avery Wang's 2003 paper. No API. No cloud. No magic. Just math.

Zappy: Building a Real-Time Workflow Layer for WhatsApp-Based Businesses
Zappy is a mobile first shared WhatsApp inbox for small businesses, designed to turn chaotic customer messaging into structured team workflows.
The core problem is not messaging, but coordination. As small teams grow, conversations become fragmented, messages are missed, and there is no clear ownership or system of work.
I designed Zappy as a real time, multi tenant communication system where every business operates in an isolated workspace, and every conversation is structured, trackable, and assignable across team members.
The system is built with a contract first architecture using OpenAPI and shared types, ensuring the backend and mobile app stay fully in sync as the product scales.
Real time updates are handled through Socket.IO, with fallback polling for reliability across environments.
On top of this communication layer, AI is embedded directly into workflow moments, not as a separate tool. It assists with reply suggestions, conversation summaries, tone rewriting, sentiment detection, and off hours responses, all aimed at reducing cognitive load and response time for small teams.
Zappy is ultimately a workflow layer for WhatsApp based businesses, focused on structure, speed, and clarity in customer communication.
I built a machine that turns you into a literal GOAT 🐐
Introducing The GOAT-i-fyer, my official submission for the #ElevenCreative Challenge!
Drop in any selfie, and this multi-node template will show you how you'd look as a fabulous goat - PLUS it'll build a fully voiced, lip-synced version of your new alter-ego.
What makes this a true G.O.A.T. workflow:
⭐ It scans your photo and maps your unique real-world traits (like your hair color, expression, or accessories) directly onto a high-fidelity goat avatar
⭐ It doesn't stop there - it also scripts a punchy, spoken monologue that syncs perfectly to the goat's mouth movements
Try out the template, and PLEASE show me your results in the comments!
& if it makes you laugh, smash that UP-GOAT button (if not now, when?) 👇
This is so cool and fun!
Built a Pixar-style animated jungle short film workflow using ElevenCreative 🌿
“KAIRO: The Last Rain Singer” is a 1:30 cinematic story about a young black panther trying to save his jungle after the rain disappears.
The biggest challenge was making every AI-generated scene feel like ONE real movie instead of disconnected clips.
I focused heavily on:
• character consistency
• smooth scene transitions
• matching ending/starting frames
• cinematic camera movement
• emotional music + sound design
• continuous jungle atmosphere
The workflow combines image, video, voice, music, and SFX generation into one cinematic pipeline.
Really excited about how natural and emotional the final flow feels.
