Software Engineer with strong frontend expertise and full-stack experience building and evolving production software across different products, domains, and engineering environments.
I work across the software development lifecycle — from understanding product and business requirements and designing technical solutions to implementation, testing, deployment, production support, and continuous evolution.
My experience spans frontend engineering, backend services and APIs, databases, integrations, cloud infrastructure, CI/CD, performance, accessibility, and software architecture. Frontend remains one of my strongest areas of expertise, particularly in complex product interfaces, frontend architecture, design systems, and the JavaScript/TypeScript ecosystem.
I've worked with products and engineering teams in Brazil and the UK across fintech, SaaS, AI-driven products, cybersecurity, healthcare, creative software, and other domains.
Creator and maintainer of sdd-agentic-flow, an open-source, local-first Spec-Driven Development toolkit and engineering harness for AI coding agents.
It brings structured specifications, execution workflows, guardrails, evidence-based validation, CLI tooling, and human-in-the-loop governance to AI-assisted software development.

- Full-Stack Product Engineering
- Software Architecture & System Design
- Frontend Architecture & Design Systems
- Backend Services, APIs & Integrations
- Cloud, CI/CD & Production Delivery
