Async Labs: We build custom SaaS web applications.

Building a SaaS web application is still hard. Modern web tooling lets you build delightful user experiences. The downside is that you have to stay up to date with this ever-growing and ever-changing tooling (frameworks, libraries, concepts, ideas). If you appreciate readable, maintainable and extendable code, consider working with us.

With new clients looking for a long-term engagement, we like to start with a trial project (1-3 weeks). If we're both happy, we'll continue the engagement and bill per week based on the number of hours we work that week.

Currently, we are very interested in supply chain, logistics, and inventory management projects. If you are building or planning to build a project in any of these areas, tell us more.

We charge $150/hour. Our max capacity is up to 3 senior-level engineers.

About you

You can be at any stage of development: no sketches and no codebase, codebase that needs a full refactor, codebase that needs a new feature, etc. You can be an individual, startup, or small business.

You can be building a new SaaS product or an internal tool to make your existing business more efficient. We prefer to work with clients who have some technical background. You don't have to code every day, but understanding project structure and web architecture will be very helpful.

We give preference to codebases with React.js on frontend and Node.js on backend. We write both frontend and backend with TypeScript. If you bought our SaaS Boilerplate book to build your web application, we will assign a higher preference to work with you.
