Zipperchain was a highly performant, cloud-based microservice blockchain.

Written in Go, this blockchain operated without a native currency and compromised on traditional decentralization for sheer performance and extremely low costs. It handled tens of thousands of transactions per second for fractions of pennies on the dollar.

Designed with shared data across multiple cloud providers, it allowed users full access to persistent data post-blockchain runtime.

I developed major features, including the genesis block structure, a backward-compatible blockchain configuration, and concurrency for fetching sharded data across cloud providers.

I also designed the full DevOps CI/CD pipeline to deploy Dockerized microservices into Kubernetes, with the infrastructure on AWS created by Terraform and monitored by Datadog.

Pallets was a Go monolith with a client/server architecture for writing arbitrary data to Ethereum via smart contract event logs.

Built on top of the Geth library, it used Infura WebSocket RPCs for low-latency transaction confirmations. It featured a high-throughput concurrent worker pool backed by Redis and used rotating wallets to handle pending transactions. It used dynamic gas pricing via a gas oracle to prevent rejected transactions from underpricing during network surges.

An opinionated testing tool for enhancing Go Testify test suite subtests. While Testify offers suite setups and teardowns for unit tests, it does not provide setups and teardowns for unit subtests. This tool allows users to easily add setups and teardowns for their testing suite's subtests with a simple function call.

Prettify your Go output into human-readable JSON with method chaining.

It allows users to use method chaining to replace their boilerplate JSON marshaling and easily output to stdout, stderr, or anything that implements the Go io.Writer interface—including files, and then handles the return error from the all-or-nothing method chain.
