Project Summary

TechWings (formerly Mentalstack) developed two full-stack applications — a blockchain-based investment app and a winery platform driven by a taste-analysis algorithm — deployed across web, iOS, and Android. The vendor progressed from foundational work to end-to-end development, delivering polished, user-friendly designs and personalized UX. The client praised the project management and product quality but noted recurring small post-release bugs that led them to hire an in-house developer for fixes.

Key Challenges

  • Complete trial projects for two clients
  • Build a blockchain investment app from provided mockups
  • Design and develop a winery recommendation platform without raw mockups (redesign from PNGs)
  • Deliver cross-platform full-stack applications (web, iOS, Android)

Project Deliverables

  • Full-stack mobile and web applications
  • Blockchain investment app
  • Winery recommendation platform with a taste-analysis algorithm
  • Early web releases

Project Solution

The vendor moved from initial foundational work to end-to-end development of two full-stack applications. They built a blockchain app for cryptocurrency investments from provided mockups and delivered an early web release, and they redesigned app concepts from PNG files to build a winery platform that recommends beverages using a taste-analysis algorithm. Both products were developed for web, iOS, and Android. The client primarily interacted with a single designated project manager who served as the main liaison.

Project Outcome

  • Delivered high-quality app features appreciated by the client
  • Some post-release bugs persisted, prompting the client to hire an in-house developer
  • Maintained regular biweekly meetings and progress tracking via Jira
  • Project manager provided strong account management and prioritized the client's needs

Quality of Deliverables

The apps look stunning and are easy to use, and that's down to the huge talent on TechWings' (formerly Mentalstack's) development team. They don't pay enough attention to bugs after release. Still, they make up for it by focusing hard on core development and on keeping clients happy.
