Channeled

Customer Success app loved by Clay, WorkOS, Pocus, Mutiny

Solution Architect

A great example of what I can build from the ground up is Channeled, an enterprise project that aims to simplify client communication. Since I joined Channeled, I have rebuilt and improved every aspect of the application, building toward performance and cost-effectiveness. Here’s what I’ve worked on with Channeled: - I’ve implemented numerous integrations for platforms such as Salesforce, HubSpot, Zendesk, Intercom, Asana, Jira, Linear, etc. - I’m also responsible for the blazing-fast Slack application that creates tickets from customer messages in connected channels and syncs them across connected integrations in seconds. - I maintain the GraphQL and REST API. - I ensure our database architecture is performant and efficient. - I am responsible for our AWS architecture and other cloud services. We’ve built awesome features like broadcasts that can be sent to thousands of channels at a specific date and time, automated workflows with limitless possibilities, and a lot more!

ReadyDev

Hiring platform, a better version of Toptal

Front-end engineer

At ReadyDev, I was mostly responsible for the front-end aspects of the web application. To name a few, this included advanced candidate search, in-app messaging, social profiles, skill assessments and CV parsing. Here, we implemented pagination on an individual page basis rather than infinite scroll to structure data navigation.

Music player: Spotify's little brother

Solution Architect

As the Solution Architect, I designed the overall architecture of the music player app, selecting appropriate technologies like Next.js, TypeScript, Zustand, and Radix to ensure scalability, performance, and maintainability. I broke down the single dashboard design into a complete application with multiple features and user flows, providing technical leadership to the development team during the rapid 4-day development process.

Social Media for developers

Solution Architect

As the Solution Architect, I was in charge of creating a basic version of a social media platform made just for developers. I used Dribbble for design ideas and chose technologies like Next.js and TypeScript to build a platform that looks good and is easy to use. This platform solves the problems developers have when they try to work together, share what they know, and connect with others on regular social media sites. I made sure developers can easily sign up with their Google account, find posts they care about in their "My Feed," save posts they like, talk to other developers, and stay up-to-date using "Official Channels" for popular programming languages, tools, and frameworks. My goal was to make a platform that helps developers work together, learn from each other, and make friends in their community.

Crypto app with LIVE updates

Solution Architect

I was mainly in charge of picking the right tools and deciding how to build the crypto app. I chose WebSockets to show live coin prices and made sure the app worked well and was easy to use. I also had to find the best way to get all the data we needed, especially for the portfolio page where users track their coins. When we ran into trouble getting old trading data for the charts, I came up with the idea to change the project and make a server to save this information. My job was to guide the team and make the decisions about how the app should work.
