Client's Testimonial

"We were stuck. Our platform was our entire business, but we couldn't fix bugs, let alone build new features. The Developers.dev team came in and performed what I can only describe as 'code archaeology.' They documented everything, stabilized the system, and within a few months, started delivering the features our customers had been demanding for years. They didn't just save our platform; they saved our business."

Client Introduction

A mid-sized EU-based company providing a popular LMS to over 200 universities and corporate clients. Their platform, originally built with AngularJS, was struggling to keep up with user growth and competitor features. The original development team had left, leaving behind a complex, poorly documented codebase.

Problem

The client's business growth was being throttled by its own technology. The unstable and brittle AngularJS application led to frequent outages, a growing backlog of bugs, and an inability to implement a modern, interactive user experience. They were losing customers to more modern competitors and needed an expert team to take immediate ownership and turn the situation around.

Key Challenges

Lack of Documentation

The existing codebase was a "black box" with no technical documentation or knowledge transfer.

Severe Performance Bottlenecks

The platform became unusable during peak hours (e.g., exam periods).

Inability to Integrate

Adding new third-party tools (like plagiarism checkers or video conferencing) was nearly impossible.

Recruiting Dead End

They had spent months trying and failing to hire qualified AngularJS developers locally.

Our Solution

We deployed a Staff Augmentation POD to act as the client's new, permanent engineering team for the legacy platform.

🔎 Code Audit & Rescue

The first month was dedicated to a deep dive. We reverse-engineered the entire application, documented the architecture, mapped the database schema, and created a prioritized backlog of critical bug fixes and performance issues.

⚡ Performance Overhaul

We systematically identified and refactored the most inefficient parts of the application, focusing on optimizing database queries, implementing caching strategies, and fixing memory leaks in the AngularJS front-end.

🛠️ Dedicated Maintenance & Support

We established a robust support system with a dedicated ticketing portal and SLAs, ensuring all new and existing issues were addressed promptly and professionally.

✨ Targeted Feature Development

Once the platform was stable, we began working on high-impact new features, such as a new real-time chat module and integration with a third-party video streaming service, built as standalone components to minimize risk.

Implementation and Execution

Phase 1 (Weeks 1-4)

An initial POD of 2 Senior AngularJS Developers and 1 QA Engineer was assigned.

Phase 2 (Weeks 5-12)

Communication was centralized in a shared Slack channel for real-time collaboration.

Phase 3 (Weeks 13-18)

We implemented a Kanban workflow in Trello for full visibility on task progress.

Phase 4 (Weeks 19-22)

The team worked in the client's time zone (CET) to act as a seamless extension of their product team.

Phase 5 (Week 23)

We established a weekly demo call to showcase progress and gather immediate feedback from the client's stakeholders.

Phase 6 (Week 24)

All work was managed through the client's existing GitHub repository, with strict code review and pull request protocols.

Positive Outcome

✅ 99.9% Uptime Achieved

Platform stability issues were resolved within the first three months, virtually eliminating outages.

📉 40% Reduction in Support Tickets

The proactive bug fixing and stabilization efforts led to a dramatic decrease in customer complaints.

🚀 Successful Launch of 3 Major Features

The client was able to launch three new, revenue-impacting features within the first year of the engagement.

📚 Complete Knowledge Base

The client now possesses a comprehensive technical documentation repository for their platform, eliminating future 'black box' risks.
