Experience

  • ShipChain, Inc.
    https://github.com/ShipChain

    As the CTO, I oversaw the design and implementation of every project on the ShipChain GitHub between its creation in 2017 and my departure at the beginning of 2020.

    Noteworthy projects include:
    • Engine: TypeScript RPC service and secure wallet host for interacting with blockchains without requiring constant user approvals
    • Transmission: Django REST caching layer for storing and querying blockchain data
    • Smart contracts: Blockchain smart contracts for identity, notary, and escrow services built on Blockchain.
    • ShipChainMobile: a Kotlin Android application for updating tracking locations

  • Hotsauce
    https://code.netprophet.tech/netp/hotsauce

    I developed an automatic "Kubernetes Backup Manager" to take and restore live snapshots of databases and PVCs and run other administrative commands in a cluster. Version 1 was built in Django 3.0 and DRF. Version 2 is being rewritten in Go as a Kubernetes operator.

  • AnnexTracker

    This provides real-time analytics for high-volume (around 10 million DAU) advertising campaigns; it optimizes media buys for thousands of segments and data points and instantly detects outliers and problems hidden in big traffic influxes.

    After six years of operation for a book of private clients, the project was taken offline in 2017.

  • TXGun

    TXGun is a subscription management SaaS for transactions on the Ethereum blockchain. A Django and DRF back end watches for transactions matching your filters on the blockchain and then notifies you via HTTP POST, WebSocket, or email of the new event.

    I built a front end for registration and account management using React, Redux, and Material-UI. It enables developers to integrate blockchain payments or smart-contract data without having to connect to an Ethereum node.

  • Django Easy Button
    https://github.com/lwbco/django-easy-button

    An all-included "kitchen sink" set of modules I like to use in my personal Django projects; it adds zero-config support for RBAC, automatic model serializers, automatic DRF CRUD generation, metadata introspection views and more.

    Version 4 (which is incomplete) adds GraphQL/Graphene and Django channels for automated pub/sub, in-model instance contexts. An accompanying React-and-Redux project enables dynamic zero-code list/details/create/edit page views by consuming introspection metadata.

  • PayWei

    PayWei is a SaaS invoicing platform for cryptocurrency payments. It enables Ethereum users to create invoices, retain records, and request money while using the Ethereum blockchain for payment resolution.

    Technologies: Django, DRF, React, Redux

  • Capdax Crypto Exchange Alpha

    I wrote the alpha prototype of a cryptocurrency exchange, tested privately among dozens of users and enabling real-time order books for hundreds of various tokens and coins. The project was functional for deposits, withdrawals and trading of Bitcoin, Monero, and any coin on the Ethereum network.

    The codebase (Django 2, React, Redux) was audited and approved as secure and effective by a team of advisers and professionals including a MariaDB co-author. The project is now defunct, as management has abandoned it.

  • Ethereum Powerball

    Ethereum Powerball is a fair, decentralized, trustless player-owned-lottery proof-of-concept. It was built using a smart contract on the Ethereum blockchain.

    I developed the front end in React (with hooks) for buying lottery tickets or investing in shares of the house. I also tested it to ensure it was fast, fair, and effective for up to billion-dollar jackpots. I also developed the accompanying Flask-and-Django projects for security analysis and regression testing.
