Soy Sebastian Sala - ingeniero de software en Blinks Institute enfocado en construir productos digitales.

At Blinks, I worked on expanding and modernizing the payment ecosystem. I implemented card payments via terminals, mobile payments through CoDi, and online transactions, giving the platform multiple ways to process sales.

I designed and launched a cross-platform mobile app with Apache Cordova, including custom plugins to integrate bank card payments. I also shipped Flutter applications for additional mobile experiences across the product.

I contributed to an internal web builder—templates, blocks, and flows—to assemble and publish pages with less friction for stores and marketing content.

On the conversational side, I created a WhatsApp chatbot that automated sales across several stores, with dynamic product catalogs and promotional offers. This improved customer interactions and streamlined operations.

At SCISA, I focused on financial operations and system performance. I implemented Stripe payment integrations, broadening the payment options we could offer and supporting more billing scenarios.

I also designed and built an automated billing system that generated and managed invoices, reducing manual work and improving operational efficiency.

I spent time refactoring components for reusability and simplifying dependencies, which cut down complexity and made the codebase more maintainable.

By identifying and fixing performance bottlenecks in critical flows, I improved load times by roughly 25% and made the application more responsive overall.
