What I'm looking for

I am seeking senior engineering roles where I can own architecture and infrastructure, drive TDD and documentation practices, automate processes, and deliver scalable, cost-efficient systems.

I am a Senior Full-Stack Engineer with 15+ years of experience focused on PHP/Laravel and React ecosystems, delivering tested, secure, and high-performance web systems. I lead legacy migrations, build scalable architectures, and implement TDD culture to improve code quality and team autonomy.

As a technology partner and lead engineer, I architect infrastructure and automation that reduce operational costs and manual work — including a full legacy migration to Docker/Hetzner, a multi-tenant headless CMS in production, and marketing automation integrations using WhatsApp, n8n, and Chatwoot.

I take ownership of the full application lifecycle, prioritize documentation (ADRs) to eliminate hero culture, and maintain a strong focus on observability, CI/CD, and static analysis to ensure maintainable, production-grade systems.
