Staff Software Engineer - Engineering Manager
Hi, I'm Levi, I'm an experienced Staff Software Engineer and Engineering Manager with an emphasis on building secure, scalable, and performant web applications. I deeply care about security and reliability at every level of the stacks we rely on and I go out of my way to fully comprehend every detail in the complex systems that we rely on.
I'm the author of @levischuck/tiny-cbor, a minimal library for encoding and decoding CBOR in JavaScript. It supports the critical path for many WebAuthn implementations and currently has 825628 weekly downloads on npm. Interested? See where my code has gone.
I lead an engaged team of engineers that develop and deploy scalable, performant, highly available, secure, and frugal web services that power EatStreet on AWS. I regularly mentor and educate junior to senior engineers on technical skills and personal project management. I'm an effective communicator who raises the bar for lasting cross-team change in organization, software development, deployment, business operations, and security as a business and secured web applications. My leadership has reduced oncall incidents and their impact by 90%, enabled autonomy of multiple teams, and has instilled leadership and responsibility in engineers that report to me. For matters of security and data privacy, I'm the go-to expert in designing, reviewing compliance efforts and cryptography.
Before becoming a manager, I advanced EatStreet to PCI DSS Level 2 compliance, developed the backend for CCPA right to know and right to delete, outperformed F5 Silverline Shape Defense credential stuffing defenses, developed a new vertical that brought 20% more revenue, surgically rewrote and scaled order fulfillment services under pressure to handle 6 fold load at the pandemic onset, released a scalable 3000+ domain HTTPS load balancer with a custom LetsEncrypt integration, secured partner ACH data with Google Tink and AWS KMS, replaced MD5 and 3DES usage, and released an internal fine-grained authorization framework for employees and contractors.
