I am a Senior DevOps & SRE engineer with 20+ years of experience building secure, scalable cloud and bare-metal infrastructure, and I love building platform tools that solve real operational problems.
I am also a heavy, hands-on practitioner of AI agentic coding, focused on getting the most out of it. I author custom Claude Code skills and MCP servers that make AI agents go straight to the point, and keep a persistent Obsidian engineering memory that gives instant recall of past tasks and projects — so AI acts as a long-lived teammate rather than a one-off assistant.

Technological Degree in Computer NetworksGPA: 8 out of 10Thesis:Analysis of the Microsoft Unified Communications (UC) architecture for VoIP Supervisor: M.Sc. Leonardo Garcia de Mello This article analyzes Microsoft’s enterprise VoIP solution under the Unified Communications (UC) architecture. It outlines the components—such as Microsoft Office Communications Server 2007—and their interactions with other Microsoft systems. The solution integrates with IT infrastructure and existing telephony (including legacy PBX and PSTN) to deliver videoconferencing, audio conferencing, and instant messaging within Microsoft Office 2003 and 2007. |
Production MCP (Model Context Protocol) server exposing on-chain blockchain data as tools to AI agents. Auto-generates its tool surface from the backend GraphQL schema via introspection, and integrates x402 pay-per-query pricing so blockchain data is programmatically queryable by AI. (Private repository.)
A persistent AI engineering memory built on Obsidian (PARA “compound engineering” vault) so every AI coding session has instant recall of past tasks and projects — no re-explaining context. Ingest → lint → query pipeline with hybrid contextual retrieval (BM25 + rerank), driven by custom Claude Code skills, subagents, and hooks. (Private repository.)
A Python tool that improves on the standard AWS pricing calculator by comparing the additional cost of a change against an account’s existing spend — turning “what will this cost” into “what will this add”.
