Documented architectural decisions behind a fast, maintainable portfolio.Continuous learning
I keep sharpening the technical foundations behind my day-to-day work. These recent courses reflect a deliberate focus on understanding the platform deeply, from the JavaScript runtime to the browser itself.

Advanced JavaScript course focused on the language fundamentals and runtime concepts behind modern frontend development. Strengthened my understanding of execution context, closures, asynchronous programming, promises, and JavaScript internals.
Open certificate
Advanced JavaScript course focused on building robust web applications with native browser APIs and modern Vanilla JS. Covered DOM APIs, Web Components, browser capabilities, performance, and architectural decisions around when a framework is — and isn’t — necessary.
Open certificate
Advanced training focused on understanding JavaScript from first principles. I deepened my knowledge of types and coercion, scope and closures, this, prototypes, and the language's object model, with a focus on how JavaScript interprets and executes code.
Open certificate
Advanced JavaScript course focused on understanding asynchronous execution from first principles. Strengthened my understanding of the event loop, callbacks, promises, browser APIs, and execution order, with a focus on how JavaScript coordinates synchronous and asynchronous work under the hood.
Open certificate
Advanced JavaScript course focused on modern language features introduced in recent ECMAScript versions. Covered ES Modules, generators, destructuring, tagged template literals, advanced regular expressions, and other language enhancements, with an emphasis on understanding how these features work and when to use them effectively.
