MY WORK

Multiphase Probability-Based Minting System on Ethereum

Hydra Launchpad

As Hydra Launchpad's partner, I devised a new minting technology on the EVM blockchain that enables time-based controls for determining which groups of people can mint Lottery Ticket NFTs during specific time intervals. It can also randomly selects the winning Lottery Ticket NFTs that can be swapped on-chain for the project's main art NFTs. Furthermore, it allows holders of non-winning Lottery Ticket NFTs to process their NFTs for a refund on-chain. I also implemented microtransaction fees to further increase the client's revenue stream beyond mint proceeds, as well as gas-efficiency mechanisms that saved them 89% in Ethereum gas fees.

Wagering System for PvP Games on the Blockchain

Darknet Games

Darknet Games is a marketplace for games and a social network where people can play against each other in crypto-wagered matches. As Apollo Launchpad's lead engineer, I implemented their wagering system for EVM-compatible blockchains (i.e., Ethereum, Avalanche, etc.) so that any partnered game developers could easily integrate and list their games on the platform.

Better Managing Client Payments & Communications

Collectio

Collectio is a platform that improves businesses' scalability by automating their accounts receivable process. I helped build the backend of their system that parses data from bank payment files (PAD, EFT and DEFR files) and automates the visualization and analytics of payment data. I also developed the web dashboard that enables businesses to effectively assess debtors and their payment activities and schedule automated invoicing.

ABOUT ME

AN ENGINEER & ENTREPRENEUR

I graduated from the University of California in Berkeley in 2019 with a B.A. in Public Health. I leveraged some of the R-programming I used for my stats courses and taught myself full stack development after I graduated to become a software engineer and an entrepreneur.

I have since started a software business to help people better manage their web resources, freelance and occasionally post coding tutorials on YouTube.

I launched and minted out (fully sold out) a NFT project earlier this year, which equipped me with the experience and skills necessary to build my own NFT Launchpad, the Apollo Launchpad. Through Apollo Launchpad, I help creatives and businesses take their creativity and artistic and marketing ideas onto the blockchain as NFTs. I have also continued to found my own projects, with the most recent one being Critically Endangered NFTs on Immutable X, a Layer 2 scaling solution on the Ethereum blockchain.
