Projects

Correla

"Correla" is a social directory app designed to facilitate meaningful connections through correlation, conversation, and community. With the tagline "Find amazing people. Make new connections," the app introduces a unique approach to discovering and connecting with others. Using the concept of "tags", users can create profiles that highlight their interests, passions, and associations through simple words and phrases. The primary goal is to enable users to meet their next friend, partner, mentor, teammate, or connection. Each profile provides links to connect with the person on their preferred platforms, including social media or email. I was proud to build a fun social directory app (complete with profiles and search functionality) from scratch using Next.js, Vercel Postgres, and Prisma. This was one of my first (of many) major productions that I released on my own as a passion project and have iterated on for years.See More

Thought Saver

As the Chief Technology Officer (CTO) of my previous job, I undertook the responsibility of revamping and rebuilding the "Thought Saver" app. Prior to me joining, the small team, who recently lost its last and sole developer, only had an initial, rough version of a web app. I take immense pride in the extensive overhaul I executed on this project, as the sole developer and thus chief architect. From completely redesigning the interface to rearchitecting the entire stack, I transformed the project into the widely used production app it is today. First, I migrated the app from an outdated framework (KrakenJS) to a clean and concise React frontend, and then I upgraded the database from an old IBM CouchDB to a modern NoSQL document store. Implementing a similar architecture to my previous projects, I built a React web app and React Native mobile app that both share code, logic, and a Redux store to enhance development efficiency. The objective of "Thought Saver" was to leverage the science of spaced repetition, aiding users in storing their ideas on digital flashcards and transferring them into long-term memory through progressively spaced review intervals. I'm most proud of the success of migrating and revamping every aspect of this project, including even the core algorithms and logic that implement the spaced repetition feature.See More

Monthly Moments

"Monthly Moments" is a React web app and React Native mobile that I conceptualized, designed, and developed entirely by myself. It helps friends stay connected and share monthly updates with each other, highlighting the significant moments in their lives. The primary goal behind its creation was to provide a simplified, minimalistic, and focused social connection experience. I'm most proud of the app's minimalist interface, using only the essential features on each screen to serve the mission of this project: simple, periodic social updates. I built an architecture that allows both the React web app and the React Native mobile app to have overlapping/shared code, including the Redux store and database interactions. I'm most proud of this platform architectural approach, which has proven successful as I've utilized the same methods in subsequent projects.See More

When Tho

"When Tho" is a web application that I developed using the full-stack JavaScript library called Remix. As the sole developer of this project, I took on the responsibility of designing and implementing every aspect of the app, with a few exceptions such as session management code and the Microsoft integration, which were handled by my collaborator. The main objective of the app was to simplify group event scheduling, particularly for individuals in different time zones. By integrating with Google Calendar, users could easily share their availability, making it effortless to find a suitable time for their events or calls. Throughout the development process, I had the opportunity to gain valuable experience working on a full production RemixJS app. I'm especially proud of the custom interface I designed, which perfectly catered to the project's requirements. It was an enjoyable and iterative process, and I'm delighted with the final result. To this day I am still iterating on this and hope to release it out of beta in the coming months.See More

Call Me Up

"Call Me Up" is a simple audio calling app I developed that serves as an effortless platform for instant 1:1 audio calls, reminiscent of traditional phone calls, but conveniently accessible for free on the internet. The core concept behind this app was to create a solution simpler than popular alternatives like Google Meet, Zoom, or Discord, focusing solely on facilitating audio conversations between two individuals. It allows users to initiate spontaneous calls or schedule them for later, providing the freedom to connect without the need for video, usernames, or additional features. The interface of the app is intentionally minimalistic, with a few essential actions streamlined for intuitive and straightforward usage. To enable seamless connections and audio streams, I implemented the open-source JavaScript library called PeerJS. One of the exciting challenges I tackled was devising a method for two individuals to join the same room by accessing a unique URL path. This project fills me with pride as it encapsulates the essence of a basic "phone" experience, leveraging the simple power of the internet's connectivity.See More
