Featured Products & Case Studies

Not just code repositories, but real-world SaaS architectures and business solutions engineered for performance, resilience, and scale.

Enterprise Core - redefy GmbH

DTS – Construction Defect Management

Enterprise construction defect management portal with high availability and automated CI/CD.

Problem:

Managing construction defects requires precise documentation, reliable data entry across distributed teams, and high fault tolerance.

Architecture & Solution:

Developed a robust, web-based enterprise portal utilizing Angular and Material Design principles. Implemented automated GitLab CI/CD pipelines and Docker containerization to ensure stable, scalable deployments.

instrufy – Training Management Suite

Cross-platform training operations and offline participation tracking suite for distributed teams.

Problem:

Organizations struggle to synchronize training schedules, materials, and offline participation tracking across mobile and web interfaces.

Architecture & Solution:

Built cross-platform mobile and web applications using Flutter. Engineered robust Offline-First architectures with local data storage and Riverpod state management to ensure continuous operation without internet connectivity.

re.use – Asset Management & Commerce

Enterprise asset lifecycle tracking and real-time commerce platform built on a scalable monorepo structure.

Problem:

Fragmented asset tracking and commerce operations lead to data silos and inefficient deployment cycles for large codebases.

Architecture & Solution:

Architected a scalable Flutter Monorepo utilizing FVM and Melos for efficient workspace organization. Integrated REST-APIs and Firebase services (including Push Notifications) for real-time commerce synchronization.

FMSH – Inventory Web Software

Modern web-based inventory ecosystem engineered with user-centric UI components and AI-assisted velocity.

Problem:

Legacy inventory systems lack modern, user-friendly interfaces and struggle with agile feature iterations.

Architecture & Solution:

Developed functional web components with a strong focus on UX/UI best practices. Utilized AI-assisted engineering tools (Cursor, GitHub Copilot) to accelerate feature delivery and maintain high code quality within agile Scrum/Kanban cycles.

FairShare – Group Expense Engine

Clean Architecture Flutter monorepo with Cloud Firestore real-time sync and Riverpod state management.

Problem:

Travel groups and flatmates struggle with multi-currency expenses and messy debt settlements, especially with poor internet connectivity.

Architecture & Solution:

Engineered a Flutter monorepo (Melos) utilizing Clean Architecture. Implemented Firebase Cloud Firestore for real-time synchronization and offline caching, managed by reactive Riverpod state and automated CI/CD pipelines.

SweetOps – Offline-First POS & Inventory

Resilient offline-first Point-of-Sale with local Drift SQLite and background Symfony sync.

Problem:

Retailers lose revenue due to manual stock errors and POS downtime when internet connections fail.

Architecture & Solution:

Built a resilient offline-first architecture. The Flutter frontend reads directly from a local Drift (SQLite) database, utilizing a background outbox queue to seamlessly sync transactions with a Symfony 7 (PHP) and MySQL REST API.
