ABOUT ME

Solutions Architect · Self-taught developer

Over 16 years I held different roles — developer, tech lead, DevOps specialist, and architect — and that left me with something more useful than a title: a complete vision of the solution lifecycle.

I understand what each decision implies from the inside: how it's founded, how it's governed, how it's implemented, how it's tested, how it's deployed in CI/CD, and how it's improved over time. Not just the part that shows up in a diagram.

My key strengths

Over 16+ years I've worked in different contexts, but I always come back to these four areas. It's where I have the most experience, the sharpest judgment, and where I enjoy solving problems the most.

Cloud Architecture & Migration

Scalable architecture design in Azure and AWS. Migrations from legacy systems, AS-IS / TO-BE strategy, and infrastructure decisions with a long-term vision.

DevOps, CI/CD & Automation

Pipelines with GitHub Actions and Azure DevOps. Process automation with n8n. Infrastructure that deploys and monitors itself — less friction, more focus.

AI across the development lifecycle (SDLC)

I speed up how teams build software with AI: GitHub Copilot adoption, coding agents, and AI-assisted code review and testing. I standardize and govern its use to add speed without losing quality.

Business-facing AI solutions

I take AI to product: agents and assistants on OpenAI, Claude, Gemini and Azure OpenAI, with RAG over your own data and process automation. Governed and observable from day one — just AI that moves the numbers.

Real results

No client names due to confidentiality — but with real metrics. These are the transformations that make the difference.

Solution architecture for business initiatives in banking

Business teams were moving forward with their own initiatives without aligning with bank policies and standards, generating technical and regulatory risk. I designed AS-IS / TO-BE solutions using C4 methodology, guiding each team so their proposals fit within the corporate architecture before entering development.

Automatic bank reconciliation system

Executives were manually reconciling bank statements against pending payment operations — an error-prone process that consumed hours every closing cycle, coordinated over a shared Excel spreadsheet that was a constant source of outdated versions and editing conflicts. I developed a platform where the executive uploads the statement and the system automatically generates the match with business operations, detecting differences instantly and eliminating the spreadsheet entirely.

Transversal integration bus for SaaS providers

When operations are distributed among multiple SaaS providers, communication between them becomes chaotic: no traceability, no control, and with silent errors difficult to detect. I implemented a custom Service Bus on Azure as a transversal channel, providing complete visibility over every message between providers and turning the integration into something governed and auditable.

DevOps Isn't a Trend: It's the Common Language Your Team Needs

After years of working on technology transformations across organizations of all sizes, I've reached one clear conclusion: DevOps doesn't fail because of missing tools. It fails when we treat it as a project with a deadline.
