About Antonio

I help engineering teams fix three common problems: unclear architecture, slow delivery, and rising cloud costs. I am a System Architect and Staff Engineer with 10+ years of experience. I work hands-on and lead technical decisions. I can analyse your system, propose a simple plan, and help your team execute it.

Tech focus: Node.js, React, Next.js, Astro; Cloudflare (Workers/Pages), AWS; Docker, Kubernetes; MongoDB/PostgreSQL; CI/CD with GitHub Actions; patterns like microservices, modular monolith, serverless, and DDD.

How I work: I start with a short architecture review (POCs/RFCs when needed), choose the simplest design that fits (KISS, YAGNI), remove unnecessary services, and use edge/serverless where it brings real value. I mentor developers and align with product so changes ship faster and safer.

Engagements: hourly consulting, architecture reviews, modernization roadmaps (monolith ↔ microservices ↔ serverless), Cloudflare/edge workshops, performance and cost optimisation.

Part-time availability. Remote. Clear communication and business goals first.
