I'm Sebastian Sala — a software engineer at Blinks Institute focused on building digital products.
While my main focus is web development, I keep an open mindset toward different branches of software, always eager to learn, experiment, and take on new challenges.
My primary focus is on building software, design systems and growing as a versatile developer.

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 also designed and launched a cross-platform mobile app using Apache Cordova, where I built custom plugins to integrate bank card payments.
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.
On the frontend, I reinforced the architecture by enforcing component reusability and coding standards, making the system easier to maintain and ready to scale.
At SCISA, I focused on financial operations and system performance. I implemented Stripe payment solutions, broadening the transaction
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 25% and made the application more responsive overall.
