Project details

I will build a clean, scalable, and well-structured REST API using .NET 8 and Clean Architecture.

This project is ideal if you need a solid backend foundation for a web or mobile application, an MVP, or a system that can grow over time without technical debt.

The API follows industry best practices such as SOLID principles, separation of concerns, and DTO-based communication. It includes a complete CRUD flow, validation, database integration, and interactive API documentation via Swagger.

I focus on clean code, maintainability, and clear communication throughout the project, ensuring you receive a solution that is easy to understand, extend, and deploy.

Each project includes one revision round (Two for Advanced tier). Additional features or changes outside the agreed scope can be added as a separate milestone.

About Martin Alejandro

Martin Alejandro P.Status: Offline
Senior Full Stack Developer | .NET, Node.js, Vue.js | APIs & Web Apps
Buenos Aires, Argentina - 2:19 pm local time
I am a Senior Software Developer with over 10 years of professional experience, primarily working on private and enterprise projects outside of Upwork for companies in insurance, retail, finance, and technology.

Most of my work has been delivered under NDAs or as part of internal systems, which is why my public portfolio is selective. However, my experience includes designing, building, and maintaining production-grade applications used by real businesses and users.

Core expertise
• Backend and full-stack development focused on scalable, maintainable systems
• Strong background in API design, system architecture, and integrations
• Experience working closely with product, business, and non-technical stakeholders

Main tech stack
• .NET (Core 2.1 → 8), C#, Entity Framework
• Node.js, NestJS
• SQL & NoSQL databases (SQL Server, Oracle, MongoDB)
• Authentication & security (JWT, OAuth, role-based access)
• Clean Architecture, SOLID principles, and best practices

Types of projects I’ve worked on
• REST APIs and microservices
• Internal business platforms and dashboards
• SaaS-style backends and integrations
• Legacy system refactoring and modernization
• Payment gateways and third-party API integrations

What you can expect working with me
• Clear and proactive communication
• Strong ownership and reliability
• Clean, well-structured, and documented code
• Focus on long-term maintainability, not quick hacks

I’m currently available for part-time engagements (around 4 hours per day), fixed-price projects, and long-term collaborations.

If you’re looking for a developer who understands both business needs and solid engineering, feel free to reach out — I’d be happy to discuss your project.

Project setup and architecture design

I set up the .NET 8 solution using Clean Architecture, configure the database, dependencies, and project structure, and prepare the base layers (Domain, Application, Infrastructure, API).

API development and business logic

I implement the required entities, DTOs, services, repositories, validations, and mappings using AutoMapper, following SOLID principles and clean coding practices.
