David De León Acosta

As a software architect within the consulting team, I participate in the design and evolution of modern cloud solutions on Azure and .NET 8, focused on complex and high-criticality systems.

My work centers on defining sustainable architectures over time, selecting technologies and patterns appropriate to the project's real context. I have designed solutions on Azure using App Service, Functions, Storage, and Azure SQL, as well as distributed systems with a focus on performance, security, and maintainability.

I have participated in the design of industrial platforms based on microservices, working with Kubernetes, PostgreSQL, and RabbitMQ, including defining internal versioning strategies and creating shared NuGet packages to standardize communication and reduce friction between teams.

I have also led technology modernization initiatives, migrating applications from .NET Framework to .NET 8, addressing changes in Entity Framework, performance improvements, and technical debt reduction, always prioritizing business continuity.

In the DevOps area, I have collaborated in defining CI/CD pipelines and configuring network and security policies, contributing to more reliable deployments and controlled environments.

In addition to the technical aspects, I participate in audits and technical presentations, helping to justify architectural decisions and meet key certifications. I work closely with business areas to ensure that technical solutions address real needs and not just theoretical criteria.

I have worked as a software architect and technical lead on projects based on .NET and Azure, participating in the design of solutions tailored to the real needs of each client.

My primary responsibility has been to define balanced backend and frontend architectures, prioritizing scalability, maintainability, and alignment with business objectives. On the backend, I have designed solutions on Azure using services like App Service, Functions, Blob Storage, Cosmos DB, and Cognitive Services, applying them pragmatically according to each project's context.

On the frontend, I have taken technical leadership in projects with Angular, defining best practices, application structure, and quality criteria for development teams.

In addition to technical work, I have participated in direct business consulting, helping to translate functional needs into viable and sustainable technical decisions, and acting as a liaison between technical teams and stakeholders.

I was part of the backend development team, participating in the construction of the backend for a mobile application for Legálitas, based on .NET Core and deployed on Azure.

I worked on a DDD and microservices-oriented architecture, contributing to the design and development of robust REST APIs using ASP.NET Core, Entity Framework (Code First), SQL Server, and Swagger documentation. Resilience patterns like Polly were applied to improve service stability.

I participated in deployments on Azure App Service, the configuration of the API Gateway, and the definition of communication mechanisms between services using shared libraries distributed as NuGet packages, reinforcing reuse and consistency within the ecosystem.

This experience allowed me to consolidate good practices in backend development, API design, and Azure deployment, laying a solid foundation for my subsequent evolution into roles with greater technical responsibility.
