I'm an Enterprise Software Architect and Product Engineering Lead from Argentina with 10+ years of experience designing and shipping cloud-native software. My work stands on three main practices: Domain-Driven Design, scalable distributed architectures, and AI-native engineering. Building systems where AI agents participate in development as first-class citizens, driven by precise specifications and disciplined engineering. I currently lead product and technology at Alephoo and provide solution-architecture consulting at Binks Software Solutions.

Over my career I've led monolith-to-distributed and serverless migrations, applied Test-Driven Development (TDD) and Domain-Driven Design across production systems, and built my daily workflow around Spec-Driven Development and agentic coding loops.

• The ubiquitous language is non-negotiable: code that doesn't speak the domain's language is already legacy.
• Model boundaries before technology. Most "scaling problems" are really coupling problems between bounded contexts.
• Boring, explicit domain models beat clever abstractions. The model is the code.

• A well-factored monolith beats premature microservices. Distribute with evidence, not fashion.
• Scalability is bought with isolation, idempotency and observability — not with more instances.
• The hard part of a migration is carving the seams, not deploying the services.

• AI-native means the process is designed around agents, not agents bolted onto a human workflow.
• Specs are the new source code: precise, reviewable specifications turn agents into a multiplier instead of a liability.
• Agents may write the code; engineers still own the model, the boundaries, and the proof. TDD matters more now, not less.

• SpecRalph — Spec-driven AI coding automation CLI (Go). Runs agentic AI loops on top of Claude Code, OpenCode, Cursor and other agent CLIs.
• Simple Newsletter — Free service that turns RSS & Atom feeds into email newsletters. Live at simple-newsletter.com.
• skills-update — GitHub Action for dependabot-like automated AI-agent skills management, with safe commits and path policies.
• web-archiver — Lightweight Go CLI to save websites on the Internet Archive.

• Backend & data: Go, PHP, Node.js, TypeScript, MySQL, PostgreSQL, Redis.
• Frontend: React, Vue.js, vanilla JS, semantic HTML, modern CSS.
• Architecture & infra: AWS, Cloudflare, Docker, Devcontainers, GNU/Linux, CI/CD.
• AI-native SDLC: Spec-Driven Development, agentic loops, MCP tooling, Claude Code, OpenCode, Oh My Pi.
