About Mariano

Need to integrate AI into your company, connect your tools to work autonomously, or create a fast API in Azure? I'll build it for you frictionlessly.

I am a Software Architect and Tech Lead specializing in the Microsoft ecosystem (.NET / Azure) with over 20 years of experience. My goal as a freelancer is clear: deliver maximum value to your business in the shortest possible time.

My philosophy is 100% pragmatic: I'm not a theorist. I'm the person you call to build solutions, deliver value quickly, and leave a sustainable and maintainable architecture. I know perfectly how traditional enterprise systems are built, which allows me to evolve them and securely connect them to the disruptive technologies of 2026.

How can I bring immediate impact to your business?

🏗️ Cloud Architecture (.NET 8+ & Azure): Design and implementation of scalable and clean architectures to modernize your business agilely.

🤖 Generative AI & Intelligent Automation
I give a second life to your traditional software by integrating language models (LLMs) with your corporate data. I develop solutions based on RAG and intelligent agents that automate processes, improve decision-making, and ensure security over your information.

⚡ Automation: Let's not reinvent the wheel. I design complex orchestration flows to connect your isolated APIs and systems. I eliminate manual work for your team so you can focus on scaling.

If you're looking for a senior, autonomous, friction-free profile who understands the business and can talk about pure code as well as automation and AI, send me a message and let's review your case.
