iFlow — logistics platform
National and international package logistics in Argentina, processing 15–20K orders per day and 200K+ daily operational events.
Context
Lab9 client engagement for iFlow, a logistics company operating national and international package flows in Argentina.
Work
A multi-year modernization from a hard-to-maintain PHP legacy stack toward modular Node/Next.js and .NET services across reception, warehousing, routing, tracking, distribution, and reverse logistics.
Outcome
I take ownership of backend services, integrations, infrastructure, and CI/CD across the modules I lead, keeping daily production operations running during the migration.
Details
01 Architected and shipped a centralized identity and access service from scratch — an internal SSO-style service inspired by OAuth/OIDC, with application registration, scoped permissions, and API key issuance.
02 Led the technical integration between the legacy PHP OMS and the new .NET-based Logistic Manager, which handles routing, carrier assignment, dispatch, and reverse-logistics flows.
03 Worked on middlewares that kept production operations running during the migration; handed off ongoing maintenance after transitioning to other modules.
04 Diagnosed and fixed a race condition in the new-customer onboarding flow that caused intermittent order-creation failures.
05 Built and maintain backend services covering order updates, shipment events, carrier integrations, and operational notifications.
06 Shipped CI/CD pipelines with GitHub Actions for .NET and Node.js services across QA, UAT, and production.
07 Configured AWS infrastructure (EC2, RDS, Lambda), deployment scripts, and Linux servers directly.
