OrganRegistration prototype

SPA Web app that provides a 2-way data-binding of URL state to the stops on the Organ instrument. I had an issue with the storage, referencing, and sharing of organ registration stops. I could not find a suitable solution so built my own. I chose the Vue framework to give it a try in the hopes I’d be more comfortable with raw HTML and CSS.

• Polled for problems regarding registration from public (organists) sentiment on facebook and reddit
• Brainstormed problems, possible and current solutions on miro miro-link
• Prototyped low-fidelity web design on excalidraw
• App example with (multiple registrations): multiple-registrations-example-live-app

Used: Vue3, HTML, CSS

PeerPrep

• A platform for users to pair up and solve programming algorithm questions to skill-up for technical interviews. It matches users based on selected criteria (difficulty and topic). It allows them to choose an algorithm question, code it in a code editor that runs in a sandboxed environment, communicate via a chatroom, and get assistance from an AI chatbot.
• Project (5 members) in CS3219 Software Engineering Principles and Patterns across (8 weeks)

Used: NextJS, React, TypeScript, tRPC, tailwind, Prisma, MongoDB, PostgreSQL, Google Cloud Run

Static Program Analyzer

• Program to parse in a simplified programming language (“SIMPLE”), generate and store necessary information in appropriate data structures in database, and then support querying relationships within source code. Consists of 3 main subsystems, the Source Parser, the Program Knowledge Base, and the Query Processor.
• Guided Group Project (6 members) in CS3203 Software Engineering Project across 3 months

Learnt basics of C++ within 2 weeks and utilized it, following best practices (e.g. for header files, “using” namespaces, etc.).

• Used different kinds of Bi-directional Mappers (1-to-1, 1-to-many, many-to-many) to efficiently store query relationship data to support queries.
• Weighed key design choices using design patterns (Visitor Pattern, Factory Pattern etc.).
• Rigorous documentation of architecture structure, design choices which increased experience with PlantUML sequence and component diagrams.
• Document possible extension details including implementation and feasibility.

Used: C++, Catch2 test framework, Scrum practices, Atlassian Confluence & JIRA
