From Top-Tier Sales Leadership to Backend Architecture.
Hi, I'm Javier Cifuentes Avendaño. My unique career combines 13+ years of high-stakes commercial deal-making with advanced software development and data science capabilities.
The Journey: Bridging Two Worlds
For over 13 years, I've sold complex B2B solutions — from cybersecurity and cloud to enterprise software — across telecommunications, finance, industry and technology. Along the way I closed €100K+ ARR contracts, generated €250K+ in new pipeline and learned one lesson that changed everything: deals are won by understanding real business pain, not by listing features.
I built my commercial foundation formally, earning my Business Administration Engineering degree (Marketing & Sales Management) from Universidad Mayor de Chile with Highest Distinction, and in 2026 I'm completing a Master's in Management, Strategy & Marketing at the University of Zaragoza.
But strategy without execution is just a slide deck. So I taught myself to build: backend development in Python and Django, API architecture, automation with n8n and REST APIs, and applied data science — enough to design and ship the tools sales teams actually need.
Today I work at that rare intersection: commercial strategy meets technical execution. I build automations and applications that cut lead-qualification time by up to 40% — and every line of code is justified by one question: does this improve ROI or free someone's time? If you need someone who can sell the vision and build the pipeline behind it, let's talk.
My Working Philosophy
Every line of code and architectural decision must serve an authentic business purpose, optimize costs, or enhance customer retention.
Over-engineered systems create compounding technical debt. I champion clean, maintainable, modular Python/Django codebases that scale smoothly.
Software is written by humans for humans. Clear communication, transparency, and relentless accountability define my collaboration style.
