Mariano Alcaraz
Backend Developer · Full-Stack
Backend-focused full-stack developer. I design APIs, microservices and integrations, and take them to production on self-hosted or cloud infrastructure.
Available for remote collaboration, freelance projects and integrations.
Backend that
makes it to production
Developer based in Mendoza, Argentina. I started as a freelancer building microservices, marketplaces and online game servers, and went on as a tech lead and senior backend developer: service design, payment gateways, accounting and infrastructure.
I work across the whole stack, but I add the most on the server side: modeling the domain, integrating systems that were never meant to talk to each other, and leaving deployment automated.
Services, integrations
and infrastructure
From the API to the server it runs on: microservices, real time, payment gateways and deployments that update themselves.
- Node.js / Express — REST and real-time APIs
- C# / .NET — services and Entity Framework
- PostgreSQL, MySQL, SQL Server, Redis
- Integrations: payments, Meta / WhatsApp, Spotify, ERPs
- AWS — cloud services & hosting
- Linux & Windows Server admin
- Microservices & containers
- High-performance architecture
- CI/CD pipelines & deployments
Services
APIs and microservices
Design and implementation of REST and real-time services, with their database, authentication and deployment.
Enterprise integrations

Custom internal systems
Admin panels, stock and cash control, accounting, CRM, reports and operational dashboards built from scratch for each business.
Support & technical architecture
Performance improvements, architecture redesign, cloud cost reduction, production deployments and ongoing maintenance.
