In their words
Rails 4.0 made strong parameters the default in 2013 and the protected_attributes gem never supported 5.0; every application from the 2007 to 2012 window that still runs has either crossed that line or is still waiting to. The people below hired Allerin to build, fix and run Rails applications in that window. Their recommendations are public on LinkedIn; they are quoted here verbatim and attributed by relationship and date.
Twenty-four recommendations, 2007 to 2012, nineteen of them from clients, ten naming Rails by name. The same four themes repeat across them, so they are grouped that way. Several of the people who wrote them now lead engineering organizations. Case studies from later years are anonymous on the site, with the detail behind them under NDA.

Rescues of other developers' work
As a social bookmarking site who had a bad experience with our first Rails programmer, we were so happy and relieved to find a gifted company like Allerin. Not only has Allerin given us an amazing site, but they have been able to work around and fix the work of the previous programmer. Allerin is not only the company who build our site; they are a part of our team.
Client, founder of a consumer web product, August 2009
I hired Allerin Technology to produce the backend of a bespoke e-commerce web application for my company. They were timely, courteous, trustworthy, knowledgeable, patient and tolerant of spec changes, communicated status updates on practically a daily basis, and were even willing to help me with technical queries weeks after the project was completed.
Client, e-commerce, November 2009
He put together a great team to help execute my vision, and I loved how accessible he was, especially when our clients asked for last-minute changes.

Throughout the project, they are proactive and always at the lookout for better ways to further simplify or create better user experience. They say attitude can make or break a company. My experience with Naveen's team is that they are certainly the maker.
Client, healthcare practitioner, December 2011
Present tense
The estate we run today is the current proof: iPAM v2 on Rails 8.1.3.1 services beside a Python ML service with MLflow; NeuroSight with a Rails alert manager beside YOLOv8 edge inference; civilytics on Rails 7.2 with model training inside the app; and a set of internal applications moving from 7.0 and 7.2 to 8.1 with a per-app log of what broke, published as they are written up in the library.
