I build digital products from the inside out, with my feet on the ground: well-thought-out architecture, a healthy obsession with data, and great care to ensure everything fits together, scales, and works without drama.

My foundation is Big Data, and over time I've moved through entrepreneurship and product. From there comes a hybrid profile where backend, automation, technical SEO, and business judgment go together, not separately. I like to think about systems end-to-end, from how data is stored to how someone actually uses it in their daily life.

I treat AI as just another layer of the product: it's useful for automating tasks, enriching data, and improving how we design and maintain software... though sometimes it means burning more tokens than planned 😅. I feel comfortable on small teams, where impact is visible quickly and what we build makes sense and stands the test of time.

• Building a multi-tenant platform designed to publish niche directories and SEO with NodeJS and ReactJS
• Data ingestion and enrichment engines (ETL, crawlers, scrapers) in NodeJS
• Config-first development, so I don't fight with code every two weeks
• Content and process automation powered by LLMs

• Practical use of LLMs in real products (context & prompt engineering)
• Clean architectures in monorepos
• Automation and tooling to scale without the project becoming unmanageable
• Improving DX with AI assistance

• Small projects that tackle concrete problems, without fireworks
• Products where engineering and business understand each other and communicate clearly
• Open-source projects focused on data, automation, or product

• Node.js, backend, and product-oriented architectures
• Big Data, pipelines, and data processing
• Technical SEO, Programmatic SEO, and automation
• Realistic use of AI in development (no magic prompts or vibe coding)

If a problem repeats more than twice, it usually ends up as a script... though then I have to deal with 10-year-old backups 😅
