LAAS — Logistics as a Service

Logistics Customer Portals API Integration

Context

Designed as a "capsulated" bridge to expose internal warehouse and delivery capabilities to the commercial market. The system provides a user-friendly interface for end-clients while offering a flexible Open API for external business integrations, all while maintaining a secure abstraction layer over internal core systems.

My Responsibility

I served as the sole architect and technical lead, managing the end-to-end development of the platform. I focused on creating a decoupled architecture that could handle both high-traffic UI interactions and complex API requests. My goal was to ensure architectural integrity and system security, shielding the "Twin" ecosystem while delivering a simplified experience for external users.

Outcome

Successfully delivered a production-ready platform that enabled the business to offer logistics-as-a-service to the public. The system provides the flexibility to support both manual client operations via a modern UI and automated business integrations via API, establishing a secure and scalable gateway for external logistics management.

Twin V2 — Warehouse Management System

Warehouse Management Multi-tenancy SaaS Foundation

Context

Designed as a dedicated miniservice to address deep-rooted structural issues within the legacy warehouse logic. This system was built to decouple business-critical inventory operations from the monolith, transforming a problematic internal tool into a high-performance, sellable SaaS foundation.

My Responsibility

I designed and owned the backend architecture, focusing on building a clean domain model that resolved the "ghost stock" and calculation errors of the legacy system. I managed the transition to a multi-tenant architecture, ensuring service boundaries were robust enough to allow the WMS to function as a standalone product while maintaining reliable integration with existing order systems.

Outcome

Successfully replaced a fragile legacy module with a stable, scalable service. This transition not only improved inventory correctness but also created a new business opportunity by providing a "capsulated" application that can be deployed as a dedicated service for external clients.

Twin V2 — Fleet Management System

Logistics Delivery OperationsMulti-tenancy

Context

Part of a strategic shift to separate business units into dedicated, standalone services. This system extracted complex fleet and settlement logic from the legacy monolith, creating a high-traceability platform capable of supporting multiple business entities independently.

My Responsibility

I led the architectural design and domain modeling, focusing on defining clear service boundaries. I ensured the FMS could function as a standalone product while maintaining reliable, real-time integration with peer services and the core distribution platform. I also implemented the core correctness safeguards for the end-to-end settlement workflow.

Outcome

Established a dedicated, scalable platform for delivery execution with high data integrity. By decoupling fleet logic and implementing a multi-tenant architecture, we provided the business with a specialized, "capsulated" tool that can evolve independently and serve external clients as a SaaS offering.

Twin — In-house Distributor System

Distribution InventoryOrder Operations

Context

A large Laravel monolith serving multiple companies. The legacy architecture lacked automated testing and relied on isolated local databases, making data reconciliation a manual, high-risk process.

My responsibility

As a core maintainer for over three years, I was responsible for the long-term stability and evolution of the platform. I led the incremental refactoring of high-stakes business logic and introduced automated testing to secure legacy modules. My role involved balancing daily production support with strategic technical improvements, ensuring the system remained reliable as we expanded operations to new branches.

Outcome

Unified fragmented branch data into a single source of truth. By migrating from isolated local systems to a centralized cloud platform, we eliminated manual reconciliation errors and enabled real-time operational tracking across all companies.
