hey there, my name is

David Bloss

I develop force multiplying software

This often means building internal tooling to reduce developer friction, managing cloud infrastructure, optimizing CI/CD, configuring alerting systems, and automating away tedius tasks whenever possible.

About Me

As a passionate Software Engineer & Platform Engineer, I focus on streamlining developer productivity, optimizing the software, tools and processes of engineering products, and deploying specialized infrastructure to ensure operational excellence. Here are a few technologies I've been working with recently:
  • Go
  • Python
  • Kubernetes
  • Terraform
  • AWS
  • GraphQL
  • Node
  • Typescript
  • Neovim
  • Lua

Experience

Senior Software Developer, Platform Team - OpsLevel
Jul 2023 - Jan 2025

I built and optimized the tools and infrastructure used by OpsLevel’s customers and employees.

  • I led the Platform team in a major upgrade/rewrite of OpsLevel’s Terrafom provider. This modernization:
    • Skyrocketed test coverage from 6% up to 85%
    • Reduced development time by 40%, saving 100+ engineering hours
    • Strengthed customer trust by resolving bugs plaguing customer infrastructure
    • Provided a framework for OpsLevel’s demo account used by its sales team.
  • Leveraging my Golang, GraphQL, and internal tooling development expertise:
    • I automated OpsLevel’s Go API client development by designing self-generating code by templating a GraphQL API schema into Go data structures and methods
    • Standardized local development across 10+ projects using Taskfiles, common tasks were centralized then applied to CI, boosting developer productivity
    • Personally contributed majority of OpsLevel’s public code changes; 85% of Terrafom Provider, 76% of Go API client, and 56% of cli
  • While maintaining OpsLevel’s Kubernetes infrastructure:
    • I performed 15 AWS EKS cluster upgrades while automating the process, reducing upgrade time/effort and AWS expenditures
    • Introduced Network Policies for improved security
    • Set up DataDog’s Operator across OpsLevel’s clusters
    • Diagnosed cluster issues, resource constraints, and streamlined alerting systems
  • Instrumental in building OpsLevel’s first single-tenant AWS instance:
    • I codified AWS resources into Terrafom modules and Kubernetes manifests, expediting infrastructure maintenance
    • Configured cluster RBAC to use customer AWS IAM roles, removing OpsLevel’s need to host credentials and fostering trust with this premium customer
    • Automated majority of setup steps, expediting onboarding experience for future single-tenant customers and simplifying process for OpsLevel
Software Engineer, Developer Productivity - dbt Labs
Nov 2022 - May 2023

I worked on the Release Engineering Team, Internal Services Team, and the OSS Tooling Guild; all with the unified goal of improving developer throughput.

  • Release Engineering Team
    • I improved dbt Labs’ critical deployment pipeline by optimizing one Github Action’s time by 83% (12 minutes down to 2 minutes). This action validated and updated Helm chart values that trigger ArgoCD deployments across an array of microservices.
    • Developed and mainained the Github Actions, CI, Taskfiles, Dockerfiles, Kubernetes manifests, Helm charts, and ArgoCD that deploy dbt Labs’ products.
  • Internal Services Team
    • I standardized tool versioning org-wide by developing a Go CLI program that leveraged “asdf” configurations to reported version usage/drift, and manage local tooling upgrades and configuration. This addressed inter-project code issues, reduced subtle bugs, and improved cross-team cohesion.
  • OSS Tooling Guild
    • In a day, I developed scripts (using gh cli, bash, awk, rg) that upgraded all deprecated versions of Github Actions used by 100% of dbtlab’s CI/CD pipelines. Github was dropping node 12 support for its Github Actions and my work averted a CI/CD crisis a day before support was dropped.
    • I mentored developers across multiple teams on Github Actions/workflows best practices, Python packaging, and promoting adoption of org-wide standards.
Software Engineer - Lawrence Livermore National Laboratory
May 2018 - Nov 2022

As a cleared Software Engineer, I developed and maintained robust codebases, automated workflow processes, and mentored scientists in specialized areas of computing. My work concurrently spaned across multiple teams and my code orchestrated various simulation programs run one of the world’s most powerful supercomputers.

  • I created Saloon, LLNL’s open-source Vim plugin used to improve Python code quality. Code hosted exclusively on remote servers was largely maintained without IDEs and basic IDE features such as linting, formatting, and syntax highlighting. Saloon combined ALE (Asynchronous Lint Engine) and Prospector (collection of Python static analysis tools) with a simple Vim UI to provide a suite of configurable realtime diagnositics missing from many developers workflows. As a result, code quality noticeably improved across the lab’s physics simulation software.
  • I initiated lab-wide Python codebase upgrades ahead of the Python 2.7 end-of-life deadline by upgrading critical workflow programs, documenting the process, and delivering two technical talks to the lab’s 100+ engineers/scientists.
  • I developed a Python script that converted 15+ years of unstructured physics data into visualized metrics that compared compiler performance. These insights highlighted inefficiencies in simulation code and led to reduced runtimes of 20%.
Software Application Engineer - Workday
Jul 2015 - May 2018

Fullstack Drupal developer building Workday’s Community site.

  • Instrumental in Community’s site upgrade from Drupal 6 to Drupal 8. Developed MySQL/Drupal migration scripts for approximately 120K users, 80K media files, 850K subscriptions, 4K organizations, and 2.5M misc records.
  • Automated test development with Drupal’s PHPUnit based testing framework and behat for UI testing via a templating engine, boosting developer throughtput by 20%.
Technical Sergeant - US Air Force
Nov 2007 - Oct 2017
Air Transporation (2011-2017)

Duty positions included

  • Lead QA evaluator
  • Wing Inspection Team member
  • Vehicle Control Officer
  • Airfield Driving Program Manager
Missile Maintainer (2007-2011)

I performed inspections, repairs, and replacements on over 100 active Inter Continental Ballistic Missiles.

Education

2012 - 2015
Bachelor of Science in Computer Science and Applied Mathematics

2014 - 2016
Associate in Applied Science - Transporation
Community College of the Air Force
2009 - 2011
Associate in Applied Science - Missile and Space Systems Maintenance

Projects

Easy EPR (Feb 2017 - Dec 2023)
iOS Swift mobile
Easy EPR (Feb 2017 - Dec 2023)
The de facto iOS app used by US Air Force enlisted members to write, format, and enhance their annual Enlisted Performance Report. The quality of these reports were instrumental in determining whether an enlisted member would be promoted or not. As of 2023, EPRs have been replaced by Enlisted Performance Brief.
