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.
Work experience
Blinks Institute 2024 - Present · Blinks Institute
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.
SCISA
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.
Personal Projects
PyPix PyPix
PyPix is a fast, modern browser for the PyPI registry: instant search, rich package pages, and a workflow-oriented UI for exploring Python dependencies without digging through raw index pages.
It is built as a real-world alternative to browsing PyPI from the terminal alone—focused on clarity, speed, and discoverability.
OpenAuth — Python, Ruby & Rust OpenAuth — Python, Ruby & Rust
SDKs and libraries under OpenAuth across Python (published docs), Ruby, and Rust (openauth on crates.io)—typed building blocks for OAuth-style flows and identity APIs.
Some surfaces are still evolving; each repository reflects current scope and roadmap.
NNative Voice NNative Voice
NNative Voice installs a local speech model on your machine and turns voice into text as a desktop dictation app.
It runs fully offline, keeps transcripts on-device, and is designed for private, low-latency writing with your voice.
Great for focused writing sessions, coding notes, and hands-free drafting without sending data to external services.
