About Tullio

Transforming Business Vision into High-Performing, Scalable Digital Products.

Clients need solutions that drive revenue and scale without breaking. I bridge the gap between complex business goals and robust technical execution.

With 5 years of experience, I bring enterprise reliability and startup agility to your project as FullStack Developer and Software Engineer. Whether you need a high-conversion e-commerce platform, a SaaS, or a financial system processing millions, I deliver software that scales seamlessly.

Core Value & Proven Impact:
-Financial Reliability: Engineered systems handling $1 Billion+ monthly for the largest bank in latin america, earning the internal "Mérito" award for direct business impact.
-Scalable Growth: Developed core backends for a national ticketing platform processing $200K+ daily with zero downtime during peak traffic.
-End-to-End Delivery: Architected and launched cross-platform mobile apps, an AI fitness SaaS with Stripe billing, and high-converting multilingual e-commerce storefronts.

Why Partner With Me?
-Strategic Alignment: I speak business, not just code. I explain technical trade-offs in terms of ROI and time-to-market. No confusing jargon.
-Conversion-Driven Engineering: I leverage digital marketing and sales funnel expertise to build platforms optimized for user retention and business profitability.
-Full-Stack Capabilities: I handle the entire lifecycle—from robust backends (C#/.NET, Python, Java) and scalable cloud (AWS/GCP), to responsive frontends (React, Vue, Flutter).
