Chicken-verse Game Demo

Chicken-verse was an NFT project for which I built a 3D Dungeon Crawler demo. The game was used to promote the project and be built on in the future. I oversaw the development and design of the game. I also developed the NFT contract and minting page.

Zeedz (NFT Marketplace in React and GraphQL)

Implemented the React front end for a "play for purpose" NFT game called Zeedz. The game UI implementation includes user log-in and sign-up, purchase and unboxing experience, and inventory management for the player's digital collectibles stored on the Flow blockchain.

The front end connected to the team's existing back end, including a custom GraphQL API, AWS Cognito, integration with the Flow blockchain via the Flow Client Library, distributed file hosting with Pinata, and a few other services. Data Transfer Control Center

A service for setting up data pipelines, including the filtering and aggregation rules. The service was reimplemented to be event-driven and react to changes in various sources—AWS S3, GCP Cloud Storage, HDFS, and local file systems.

I was responsible for the following:

• Scalable data processing using queues.

• Easy no-code and low-code configuration for new data pipelines.

• Enhancing the monitoring system with self-recovery mechanisms.
