Meet Kelly and Tim

Since 2018, we have been managing multiple software businesses from home.

Tim manages Async Labs LLC, a software development agency. Tim also builds tools for Kelly's recruiting agency (internal tools, job board for biotech startups, AI-cruiter extension) and fine-tunes LLMs. Kelly interacts with customers of her agency, job board and AI-cruiter extension.

This is where we live

We live on 30 acres of forest near the Selkirk Mountains in WA state. Minutes away from the Kalispel Tribe of Indians and only one hour away from the Canadian border.

This is where we live.

Past and Current projects


Open source repos
  • We maintain two popular repos: saas and builderbook.
  • Our repos have >1000 unique visitors per week. Over 100 people sign up on our SaaS Boilerplate demo every week.
  • Our SaaS Boilerplate is the most popular open source React/Next.js/Node.js boilerplate. And it's written with productive TypeScript on both front-end and back-end.
  • We also open-sourced our internal team communication tool, Async, which separates urgent vs. non-urgent conversations.

Software books
  • We wrote and self-published two books at builderbook.org.
  • Over three years, we've sold 1000+ copies with less than 3% refund rate.
  • We make twice-a-year upgrades to our books and public repos.

Work in biotech
  • Work in biotech is a job board and a recruiting agency/consultancy for small- to mid-size biotech startup companies.
  • Regardless of experience, some candidates want more responsibility and impact. Both can be achieved by joining a small biotech startup.
  • We also build tools to automate parts of the recruiting process. We recently built AI-cruiter, a Chrome extension using multiple LLMs to parse and summarize resumes, thus saving recruiters hours of time reviewing job applicants.

Current projects
  • Applicant Tracking System powered by integrations and LLMs, built specifically for agencies.
  • Fine-tuned or trained large language models for certain industries.
  • Online book about fine-tuning large language models.

Custom development
  • We've built over two dozen products for ourselves and our clients.
  • If you are an individual, startup, or small business in need of a technical team, you will value our expertise.
  • Our hourly rate starts at $150/hr with a minimum of 10 hrs/week engagement.
  • Contact to learn more.
