Current project involves a Go-Ethereum arbitrage trading bot using multiple go routines and wallets for swapping a multitude of tokens using subgraph for DEX data collection. Abi/bin/apis are generated by a shell script calling Docker commands compiling Solidity contracts.https://nft-prayers.org is a product by Pigfox LLC which is a text based NFT minting site using an API centric approach for payment, minting, email. The minting factory is a 9 step process background go routine on Tatum API. A user enters text, which is auto detected for language so that the proper font and text alignment can be set. Then a credit card payment screen appears where the user can elect to send the NFT as a gift. Upon successful payment an image is created, the dimensions are a function of the text length.The image is uploaded to IPFS and then that hash is placed in a meta data payload to IPFS. Once this is done a Celo wallet is created, the metadata hash is placed on the Celo blockchain and ownership is assigned to the newly created wallet. The user finally receives an email with all relevant transaction ids. The application is built using Go/Golang on the back end and html, css and vanilla javascript on the front end.

(Subject to renewal, I declined to renew contract)Worked on integration tests using Go and a CLI that will enable developers to have a much faster local development environment.
