Real work. Real outcomes.
Founders and technology leaders bring Danubio in for the engineering on products that have to be right. The case studies below are the work itself.

Real-time performance analytics dashboard handling 20k req/s
Inside Real Estate launched Vitals, a daily performance dashboard for every brokerage on BoldTrail. Danubio designed and built the real-time event tracking, scoring, and aggregation service behind it, end-to-end.

Legacy Code to React: A Feature-Led Approach
How we introduced React into a legacy PHP/JS stack by delivering a fully integrated, high-engagement social feature, laying the groundwork for future modernization without disrupting the existing platform.

Rebuilding a live multi-tenant platform without downtime
CORE Home was live with pilot brokerages when Danubio took ownership of the stack. The rebuild migrated tenants one at a time onto a stronger foundation, with no cutover and no broken clients. The same platform now carries 5,000+ tenants across web and mobile.

Scaling an acquired SaaS to 350K enterprise users
Inside Real Estate acquired dashCMA in 2020 and kept Danubio on as the engineering team. Five years and 1M+ presentations later, the product is used across major national brokerages, including RE/MAX, eXp, and Berkshire Hathaway HomeServices.

Internationalizing a crypto marketplace to 40+ languages
Paxful was a peer-to-peer crypto marketplace operating globally. Over two years, Danubio built its localization layer - externalization, locale-aware formatting, RTL, and a Crowdin-backed release pipeline - that took the platform to 40+ languages.
