Application modernization case studies: live products rebuilt without downtime

Products we modernized while they kept serving their customers

If property managers refuse to use your platform until the data sync holds, if a product written over ten years ago is showing its age, if every feature costs more than the last and you do not want a rewrite, or if your MVP must be fixed or started over, the cases below are yours: a rental marketplace grown from 500 to 40,000 properties, a condo SaaS modernized for eight years, an inherited MVP rebuilt in 5 months, database kept. A software audit from $5,000 answers keep, fix or rebuild.

    Brocoders built MyRedDog, a progressive web app for C.I.A. Services, which manages 150 associations in Houston and San Antonio. Homeowners and board members see live account, compliance and document data pulled from the company's RedDog system, so staff stopped fielding those calls.

    Lake, US: Brocoders replaced the WordPress monolith with a NestJS back end and a Next.js front end and built real-time sync with property managers' PMSs through Calry, in 3 months from start to release. Six PMS partnerships now feed the marketplace, and property managers who refused to list before the rebuild list now.

    Adact, Estonia: in October 2020 Brocoders took Adact's working MVP on PHP and jQuery and rebuilt it on React, Node.js, and AWS in about 6 months, with campaign configuration in PostgreSQL and game analytics in MongoDB and AWS Lambda. By August 2022 we had added games, payments, Zapier, and a custom API, and we worked on Adact until June 2024. One agency campaign drew 567,077 visitors and 478,846 completed games in 10 days.
