* Architecting and leading an initiative across 20 developers to refactor the flow of orders through our system allowing us to properly deduplicate webhooks, reduce order import errors by up to 20% through proper ordering of webhooks, and granting much needed visibility into the entire process. * Assisting in the migration from Heroku to Kubernetes and onboarding developers to the new platform. * Reviewing and adjusting the (auto-)scaling of infrastructure leading to an annual savings of €21,000.

* Automating the invoicing process saving 6 months of man hours annually. * Writing a client library to convert OAS 3.0 API specifications to callable Python eliminating the need for maintaining internal API libraries. * Building an admin panel to allow self-service for users * Numerous small, nice-to-haves, such as: automating deploys, automating library artifact storage, building a documentation-heavy culture, and optimizing database usage/access patterns.

* Creating a pricing pipeline to better handle on-boarding new manufacturers, pricing changes, and to ensure pricing is correct, while enabling the recovery of around 16k USD/month caused by pricing bugs. * Improving service reliability (from 99.9% to 99.999%) through application supervision (systemd) and properly partitioning legacy asset management onto separate servers through NFS. * Porting core business functionality from Meteor to Elixir+React to ensure a smooth transition from MongoDB to Postgres.

* Utilizing Elasticsearch to serve as the primary search engine within our e-commerce platform--storing and indexing over 20k products with 480k derivatives of those products. * Automating the returns process to reduce the processing time by nearly 60%. * Writing ETL pipelines to retrieve and sync e-commerce data from legacy (MSSQL) databases into our modern platform databases (MariaDB, Postgres, and Elasticsearch).

* Rewriting a TCP multiplexer in Go for a 3200% command throughput gain over Python. * Creating a new service offering (Transparent Encryption Layer) allowing for customers to encrypt and decrypt files on-demand utilizing third-party storage providers (AWS S3, Box, Google GCS) without granting access to encryption keys. * Building a RESTful API (Python, Flask, Postgres) allowing cloud-based asymmetric key management, cryptography for point-of-sale devices, debit processing, and remote key injections.
