Über Projekt
We developed an AI-powered report generation system for manufacturing and construction companies. Users can upload an existing report or simply describe the report they need in plain language.
The AI automatically retrieves data, performs calculations, builds report templates, and generates tables, charts, and analytics blocks. Once created, reports can be generated on demand and refined through an integrated AI chat assistant.
The solution significantly reduced manual reporting work and made complex report creation accessible for non-technical users.
Challenges One of the biggest challenges was allowing AI to work with real business data safely and accurately. The system had to retrieve only the relevant data for each report, process it securely, and prevent any risk of affecting live production data — all while keeping the experience simple for non-technical users. Since multiple companies used the same platform, we also implemented strict tenant isolation to ensure that each client's data remained fully private and inaccessible to others.
Solution
We built a secure, sandboxed data layer that allowed the AI to work safely with business data without affecting live production records. LangChain handled the AI workflows, including data retrieveval, calculations, and report generation, while Claude powered the conversational report creation and editing experience.
Using MongoDB, we implemented strict tenant isolation to ensure each company's data remained fully private and separated.
On the frontend, we created a simple Angular interface where users could generate and refine reports through an intuitive chat-like experience.

Therapeutic Music Platform for Personalized Care
About project
The client aimed to create a therapeutic music streaming platform for healthcare providers and patients. The goal was to let care professionals manage music sessions in real time — adjusting sound intensity and emotional tone to match therapy flow. Key requirements included high-quality audio, cross-platform responsiveness, and secure, instant access for patients via QR codes or links.
Challenge
There was a clear need for adaptive music that could align with a patient's emotional state, yet organizing live sessions for remote patients often proved challenging. It was also important to ensure that listeners could connect easily and securely without registration, while giving healthcare professionals powerful tools to interactively manage music in real time.
Solution
ProtoQ built a Flutter-based app with integrated music streaming and a web interface for therapists. The platform enables real-time control of rhythm, volume, and emotion, with both live and pre-recorded sessions. Patients can join instantly without registration. The solution runs on Android and Windows, providing a secure, adaptive, and user-friendly tool for modern therapy.
Result
Patients have access to personalized therapeutic music anytime, while healthcare professionals can manage sessions in real time, enhancing the effectiveness of therapy. The app provides a convenient and secure way for users of all ages to connect and serves as an innovative tool that combines music streaming technology with professional medical support. The app is successfully used on Android and Windows platforms.
