Software development case studies: five builds, what each one replaced.

Custom web applications, SaaS platforms, customer portals and mobile apps that QalbIT designed, built and shipped for clients in recruitment, cybersecurity, sports, training and consumer productivity: written up as the problem each client came with, what we built and on which stack, and what changed for the people using it.

Every study names the stack, the engagement model and the measured outcome, so you can judge the fit before you talk to us.

Selected case studies

Custom web, SaaS and mobile app case studies.

Five products across recruitment, cybersecurity, sports, training and consumer apps: each built to a written scope, released in sprints, with the client owning the code from day one.

What each study covers

How to read a software development case study.

The format is the same on every page, because the questions you are asking are the same: what was the problem, what did they build, on what, and did it work.

  • The problem the client came with

    The workflow, the spreadsheet or the legacy system that was costing time or money, stated in their terms, not ours.

  • The build and the stack

    What we scoped, the architecture we chose and why, the technologies used, and how the work was released in sprints. The same calls show up in the products we run ourselves.

  • The measured result

    What changed afterwards, in numbers where the client tracked them: fewer double bookings, hours saved each week, one pipeline instead of four inboxes.

  • Ownership and what came next

    Who owns the code and the accounts, how the engagement continued, and what we would do differently a second time.

A write-up of one real project: the problem the client came with, what was built and on which stack, and what changed afterwards. Ours name the client, the industry, the engagement model and the measured result, so you can judge whether the work resembles yours.
These are the five where the client agreed to be named and the outcome could be stated honestly. Most of our 120+ engagements sit under NDA: we can walk you through similar work on a call without publishing it.
Yes, for a shortlisted engagement. We ask the client first and connect you directly, so the reference is theirs and not our summary of it.
Recruitment and HR tech, cybersecurity and B2B SaaS, sports club management, training and scheduling, and consumer productivity apps. The same engineering approach carries the e-commerce, fintech, healthcare, education and real-estate work we deliver under NDA.
Laravel and PHP, Next.js and Node.js, CodeIgniter, Flutter for mobile, MySQL and PostgreSQL, with Stripe and PayPal where payments were involved. Each study lists its stack and why it was chosen.
A first version of this kind typically ships in six to ten weeks; the budget depends on scope. Send two lines about your product and you get a written scope, a timeline and a price range within 48 hours, free, and yours to keep.
