Software Engineer | Distributed Systems | Cloud Architecture | Backend | Microservices | AI-Driven Engineering

Software Engineer focused on building scalable backend systems, distributed architectures and cloud-native solutions.

I work with high-criticality systems, microservices, APIs, messaging and architectural evolution, with a growing focus on applying AI to software engineering and development workflows.

Currently exploring AI-Driven Engineering, Spec-Driven Development, RAG systems and modern approaches to building reliable software.


Engineering Focus

What I'm Building

My current direction combines four areas:

                    Software Engineering
                            │
          ┌─────────────────┼─────────────────┐
          ▼                 ▼                 ▼
       Backend        Distributed Systems    Cloud
          │                 │                 │
          └─────────────────┼─────────────────┘
                            │
                            ▼
                    AI Engineering
                            │
                            ▼
                 Software Architecture

The goal is not only to build applications, but to explore how architecture, automation and AI can improve the way software is designed, developed, tested and operated.


Current Technical Direction

I'm particularly interested in:

  • Designing resilient distributed systems
  • Event-driven architectures
  • Cloud-native backend platforms
  • Architecture and scalability
  • AI-assisted software engineering
  • RAG and LLM-based systems
  • Automated testing and quality gates
  • Spec-Driven Development
  • Engineering productivity and developer workflows

GitHub Philosophy

I use personal projects to experiment with architecture, technologies and engineering practices that can be applied to real-world software systems.

Some repositories are production-oriented experiments, some are architectural references, and others are ongoing explorations.

The goal is to keep learning by building, measuring, documenting and improving.


Building software, exploring architecture, and applying AI to engineering.
