About me

I grew up among coffee, avocado, plantain and citrus in El Zulia, Norte de Santander. Each crop has its seasons — so does code.

The four crops as values

☕ Coffee

Patience · Long process · Quality

Complex projects: Symfony, architectures that last years

🥑 Avocado

Slow growth · Concrete fruit · Real value

Open source with impact: plugins with 7k+ active stores

🍌 Plantain

Foundation · Abundance · The essential

Solid backend, databases, APIs that don't fail

🍊 Citrus

Freshness · Energy · Adaptability

Versatile stack: PHP, React, Node, AI according to the problem

🤖 AI — The new seed

I don't promise AI. I deliver it.

I integrate artificial intelligence in real projects for clients. Like the farmer who adopts new techniques without abandoning knowledge of the land: judgment remains, tools evolve.

Development philosophy

CI/CD as a way of life

Continuous Improvement / Continuous Delivery
Every day a better version of the code and oneself.

"The land doesn't wait for perfect conditions to bear fruit. Neither do I."
