These are just some projects that I’ve worked on - from hackathons, university projects to adventures in my free time.

Rosetta Search – semantic code search

Natural Language Processing, Python, SQLite, Electron, React, TypeScript

• Semantic search tool that uses NLP techniques to map natural language queries like “order management” or “refund flow” to relevant source code by indexing the latent semantics of a codebase stored in commit messages.
• You can dive into the design and implementation details by reading my thesis here.

Facebook Hack-A-Project Programme

🎉 Winner • March 2019

• Won Facebook’s Hack-A-Project Hackathon with a team of 4 at the end of the 4 week programme.
• Developed a NodeJS Express server capable of supporting scalable multi-player image-recognition based games within 10 hours

ICHack 18

🎉 Winner • Best Game/AR Award • January 2018

• Built a camera-based hyperlocal treasure-hunt style game, using Microsoft Azure’s Vision (Image Recognition) APIs into an Android application that uses Google Firebase to manage sessions and multiplayer capabilities.
• A fully-functioning version of the app with full Firebase and Azure Integration was completed from scratch in the hackathon’s 24 hours.

Canvas - CRDT Collaborative Drawing App

CRDTs, Swift, Javascript, XMPP

• Built a decentralised P2P collaborative drawing iOS app using Conflict-Free Replicated Data Types
• Uses MultiPeerConnectivity for local networks and an XMPPServer for global connections
• Supports offline drawing and then conflict-free synchronisation upon re-connection, ensuring eventual consistency through CmRDTs (operation-based)

Flip • 2nd Year WebApps Project

Vue.js, Firebase, Cloud Firestore

• Built a Progressive Web App designed to help students derive correct answers in a collaborative manner.
• Designed using a mobile-first approach, and built in an Agile iterative manner using Vue.js and Vuetify (Material Design) to provide a familiar interface to users.
• Uses Firebase and Cloud Firestore for instant multi-user synchronisation and storage.
• Uses Travis CI and multiple Firebase environments for continuous integration and deployment

Pintos Operating System

C, Assembly

• Built a x86 operating system with thread scheduling, priority donation, resource management, virtual memory management and support for user programs

WACC Compiler

Java, ANTLR, Assembly, SpringBoot, Docker

• Built a compiler for a While-like language that generates executable code for the ARM11 architecture
• Consists of a lexer, parser and semantic analyser in the frontend, and a code generator in the backend
• As an extension, we also built an interactive CLI for the WACC language and hosted a web-based version of it using Docker and a Java SpringBoot server.

ARM11 Emulator and Assembler

C, Assembly

• Developed an emulator in C to replicate and represent the internal workings of an ARM-11 processor on given binary files -
• Developed an assembler to convert given source files into binary files readable by the emulator.

CrowdBeats - crowdsourced Spotify Playlists

React, Swift, Node.js Express

• Built a Node.js Express server that uses Spotify’s API to allow multiple users (from an iOS app or a simple web app) to join “party" sessions to search, suggest and vote on songs to added to the party playlist.
• Built within 24 hours with a team of 3 at ICHack 19
