About Pablo

I transform legacy systems into modern, scalable architectures powered by Generative Artificial Intelligence.

As a Software Architect and technical leader, I specialize in helping companies make the leap towards cloud-native architectures and AI-augmented workflows. I'm not just a code executor; I bring business vision, technical governance, and tactical execution to solve complex bottlenecks and scale operations.

How can I help you?

AI Integration (On-Premise & Cloud): Design and implementation of AI agents, RAG (Retrieval-Augmented Generation), and internal process automation, ensuring the total sovereignty and security of your corporate data.

Architecture Modernization: Refactoring monolithic systems into robust microservices using the modern .NET (C#) ecosystem and Cloud Computing (AWS / Azure).

Complex API Integrations: Secure, asynchronous, and fault-tolerant connection between ERP systems, financial modules, and third-party platforms (REST, SOAP, event-driven architectures).

Operational Efficiency (SDLC): Architecture audits, high-concurrency database optimization, and development cycle standardization for high-performance teams.

My approach is direct: maximum operational efficiency, reduced technical debt, and deliverables that directly impact return on investment (ROI).

Let's talk about scaling the engineering of your next project.
