Case Studies
Development of a shared online marketplace enabling small retailers to create digital storefronts and sell products directly to customers. The platform allowed users to place combined orders from multiple stores through a unified checkout and delivery process.
Objective
To empower small retailers with a centralized e-commerce solution while ensuring a seamless customer experience across multiple vendors.
Challenges
- Implementing multi-vendor order and payment logic within a single checkout.
- Consolidating inconsistent product categories submitted by different sellers.
Approach
- Designed a layered order model, where each order contained vendor-specific order lines and items, enabling accurate payment distribution.
- Introduced a standardized product category list built from vendor input and enforced across the platform.
- Oversaw architecture, development, and team coordination to ensure alignment and maintainability.
Technology Stack
.NET Core · Angular · SQL · AWS
Results
- Successfully launched across an EU market.
- Adopted by a broad range of vendors and customers.
- Achieved a 4.7★ Google rating.
- Delivered a scalable architecture allowing seamless client handover.
Comprehensive rewrite of an outdated ITSM system into a modern .NET-based architecture. The modernization preserved an existing customer base while improving scalability and enabling new feature development.
Objective
To upgrade legacy infrastructure and align the platform with modern technologies without interrupting live services or losing long-term clients.
Challenges
- Highly inconsistent legacy architecture and lack of documentation.
- Maintaining service continuity during redevelopment.
- Balancing modernization with operational stability.
Approach
- Formed a mixed team of modernization and legacy developers to ensure knowledge transfer.
- Rebuilt backend in .NET, introducing modular design principles.
- Implemented Terraform for infrastructure-as-code and HashiCorp KeyVault for secure secret management.
- Integrated WCF-based async workers for task offloading and performance improvements.
Technology Stack
.NET Core · Terraform · HashiCorp KeyVault · WCF · AWS
Results
- Successful migration to modern architecture with minimal disruption.
- Enabled delivery of new features and upgrades previously impossible on the old codebase.
- Improved maintainability, security, and long-term system viability.
Development of a logistics optimization system for a trucking company operating across multiple EU countries. The system calculated optimal delivery routes and vehicle types to minimize operational costs and streamline scheduling.
Objective
To optimize delivery organization, reduce transportation costs, and improve resource utilization through intelligent route and fleet planning.
Challenges
- Combining multiple factors like cost per kilometer, vehicle size, payload, and delivery frequency into a single optimization metric.
- Building an interactive, Excel-like interface for operational analysis and real-time data manipulation.
Approach
- Collaborated closely with logistics personnel to capture practical decision-making logic.
- Created mathematical models and formulas translating complex variables into comparable quotients.
- Designed a color-coded, interactive tabular frontend for dynamic route evaluation and adjustment.
Technology Stack
.NET Core · Angular · AWS
Results
- Delivered a data-driven optimization platform that reduced delivery costs across multiple routes and countries.
- Enhanced operational visibility and flexibility for logistics teams.
- Established a scalable foundation for ongoing optimization initiatives.
