Full Stack Developer.
The code I ship, I also break.

I'm Valentina Ramírez, a Colombian Full Stack Developer focused on Django and React.

I deliver real applications: multi-user, complex business logic, my own APIs, and frontends people actually use. Offensive mindset to write code that doesn't break, with AI integrated where it counts.

From challenge to product

Real systems in production: complex business logic, integrated AI, and security by design.

TerraCore dashboard: real-time metrics, production charts, and livestock distribution

The challenge

Agricultural producers in Colombia had no software designed for them: existing ERPs were too complex, and an Excel sheet with login was not enough to manage livestock, animal health, and production simultaneously. Operations were scattered across notebooks, spreadsheets, and WhatsApp groups.

What I built

TerraCore centralizes on a single screen everything a mid-sized farm needs to manage: livestock, inventory, production, animal health, costs, and finances. It replaces Excel, notebooks, and WhatsApp as operational tools. Built from the field with real producers in Urabá, it covers cattle, swine, equine, ovine, caprine, poultry, and associated crops (plantain, cacao, corn) in Colombia.

Root PWA

Live

The challenge

Eating with celiac disease, diabetes, or lactose intolerance means reading every label, deciphering hidden ingredients listed under other names, and finding recipes that comply with multiple restrictions at the same time, all manually and scattered across sources.

What I built

The user photographs a product and within seconds knows whether they can eat it given their active restrictions (celiac disease, diabetes, lactose intolerance), combinable with each other. Root goes beyond the scanner: curated recipes with strict filtering and an offline food diary for those who already know what they cannot eat and want to know what they can.

The challenge

Reviewing code with OWASP criteria or resolving a specific cybersecurity question means jumping between heavy scanners, scattered documentation, and outdated forums.

What I built

The developer pastes a code snippet and gets an immediate diagnosis against OWASP Top 10. They can keep asking in an AI chat that remembers the thread, without repeating context or switching between tools.

About me

I'm a self-taught Full Stack Developer by conviction, focused on Django and React. I founded Lúmina W to build my own products. I study Software Analysis and Development at SENA and English Language at Universidad de San Buenaventura, learning in parallel because I don't know how to do it any other way.

Outside of code, you'll find me in photography, behind the drums, and listening to a playlist that doesn't respect genres.
