Senior Solutions Architect · AI Engineering
Software architect and senior full-stack developer since 2008. I design architectures for financial systems and build with Spec-Driven Development (SDD): clear specifications, coding agents like Claude Code inside a controlled harness, semantic search, and automated verification before every delivery.
Open to remote, international roles and relocation · Aracaju, Brazil
GitHub Spec Kit, OpenKit, GSD and Superpowers: the spec is the contract, and code only ships when it meets what is written.
Claude Code with subagents, MCP, hooks, memory and context engineering. Clear limits and feedback at every step.
Vector databases, embeddings and RAG to give agents and products the right context.
Quality metrics for what agents deliver. Nothing moves without passing.
About me
I am a software architect and senior full-stack developer with hands-on experience since 2008. I specialize in PHP, Laravel and Flutter, with strong experience in Node.js, React, Next.js and Docker. I build scalable, maintainable systems: enterprise applications, REST APIs, microservices, mobile apps and whitelabel platforms — from fintechs like EBANX and Digio to government systems like SISU.
In recent years the practice changed: the specification became the center of the work, and coding agents now write much of it. I develop with Spec-Driven Development using GitHub Spec Kit, OpenKit, GSD and Superpowers, run agents inside harnesses with advanced concepts — subagents, context engineering, hooks, memory and evals — and build solutions with vector databases and semantic search. All with the same care for clean code, design patterns and architecture as always.
Career
Senior Solutions Architect
I work where technology meets business: designing architectures that support the full customer journey, from requirements with product teams to distributed systems, financial APIs and banking integrations built with resilience and governance. I map trade-offs and produce architecture designs that guide engineering teams clearly.
