A senior Rails and React team that has run one US SaaS product for 10 years

30 engineers, QA and DevOps. We built and still run a marketing platform used by 10,000+ real estate agents across 50+ brands. We keep the same core team on a small number of products, so nobody is spread thin. Kazakhstan company, contracts and payments in USD/EUR.

Three things we do well

Rails upgrades and legacy modernization

Fixed-price audit in 2 weeks: upgrade roadmap, risks and estimate. Then we do the work or hand the roadmap to your team. No surprises.

How we work, and why it matters to you

Four things we do on every project, not because a client asked, but because after 10 years on one product we know what breaks without them.

Alexandr Kravchenko

Founder of Maxa Tech, CTO of MAXA

9 years as CTO of MAXA and a 30-person engineering team behind it. I take the first call myself, look at your codebase and tell you honestly whether we are a fit. If we are not, you still leave with a list of risks.

What we can build for you

Illustration 'Web development'

Web applications on Rails and React

Admin panels, customer portals, editors, dashboards. A Rails monolith and React front end kept fast and upgradable for 10 years; we can do the same for yours.

Ruby on Rails

React and TypeScript

Illustration 'Mobile app'

Your web app in the App Store and Google Play

We wrap an existing web application into a React Native shell, add push notifications and native login, and take it through store review. Weeks, not a second codebase.

React Native

App Store and Google Play

Illustration 'API and integrations'

APIs and integrations

Payments, email services, data feeds, CRMs, partner APIs. Documented, versioned and covered with tests, so the next integration does not break the previous one.

REST API and webhooks

Payments, email, data feeds

Illustration 'AI features'

AI features inside your product

Self-hosted models for image upscaling, object removal and generation, plus text assistants. Running in production for 10,000+ users; your data stays with you.

Self-hosted models

In production

Illustration 'Graphic editor'

Browser design editor

A browser-based editor with templates, locked brand elements and print-ready output, used daily by 10,000+ non-designers. If your product needs an editor, we have built one that survived production.

Templates and brand locks

Web-to-print

Illustration 'Email builder'

Email builder on MJML

Drag-and-drop editor that outputs valid MJML and HTML, renders correctly in Gmail and Outlook, and plugs into Mailchimp or your own sending pipeline.

Gmail and Outlook safe

Illustration 'Team and process'

Team reinforcement and a working process

Product companies often run without a strict system. We join your team and set one up: sprints, code review, CI, weekly demos and written reporting, so you see what was done and what it cost.

Dedicated engineers

Weekly demos and reports

Ten years on one product taught us what short projects never do

How to keep a Rails monolith fast after 10,000 merge requests, how to run CI that people trust, how to ship AI features to customers who pay. Now we bring that to a few more companies.
