Andrey Sitnik
Hey! 👋 I’m Andrey, I lead frontend development at Evil Martians. I’m also the company’s first hire.
I’m an expert in open source for JavaScript, with 17 years of experience. I’ve created several industry-standard tools, including Autoprefixer, PostCSS, Browserslist, Nano ID, and Nano Stores, which account for 0.7% of npm downloads. Some have been recognized by Google, Vercel, and ElevenLabs as foundational tools of modern engineering.
About me:
- I enjoy creating tools to automate developers’ flow, such as Autoprefixer and PostCSS.
- My current passion is sync engines and using CRDTs to make the frontend and backend best friends.
- I’m continuously training new developers through one-on-one conversations and public speaking. I’ve presented at conferences in New York, London, Beijing, Tokyo, Moscow.
In my work, I like to focus on adding value for users and businesses rather than simply checking off tasks. Outside of work, I try to promote language diversity and a digital nomad lifestyle. Apart from the clients on this list, I’ve also worked with Decagon and Synonym.
Series D AI concierge platform
Problem
The company needed to onboard new team members, including a large intern group. To start working, all new members needed to install each tool individually in a virtual machine. Getting the working environment up took over 30 minutes plus wait time.
Solution
We built a containerized development environment that packages the entire stack into a single reproducible setup, replacing manual onboarding with a single script. We owned the initiative end-to-end, designing the isolated environment, adapting the backend to support it, and working directly with new team members to solve issues as they went through the process.
Results
- Cut onboarding time from 30+ minutes to about five minutes
- Delivered a secure, isolated development environment that scales to onboard contractors safely
- Reduced exposure to potential supply chain attack risk by separating developer environments from production
- Established a more consistent, maintainable frontend foundation
Major gaming platform
Problem
The company needed to modernize and standardize the creator studio’s internal UI component library, but had opted to direct in-house resources in a different direction.
Solution
We built a new version of the UI library in Luau React and used it to rebuild several plugins, facilitating the conversation between designers and engineers. We also set up infrastructure for the new creator studio plugins, and participated in the development of the Luau Markdown renderer. We identified opportunities to optimize their designer-developer collaboration, and thus, improve delivery speed.
Results
- Delivered a new UI Foundation Library and integrated it into the creator studio
- Improved cross-team collaboration
- Increased team velocity and accelerated feature releases
Akeero
Problem
Security teams like Akeero, an AWS architecture audit platform, need to audit complex AWS architectures but existing tools are just visualization software that can’t formally describe system relationships or support team collaboration.
Solution
We built Akeero a custom diagram composer with real-time collaboration, optimistic UI, and formal relationship modeling using SVG-based architecture and Logux for conflict-free data synchronization.
Results
- MVP in 4 months with collaborative real-time editing
- $1.2M pre-seed funding within one year of founding
- 10x smaller bundle size (315KB vs. 2MB industry average)
- Set new standard for collaborative security architecture tools
- Successfully launched with real users and continued independent development
