Crafting scalable, high-performance web applications with modern technologies. Specialized in Angular, microservices architecture, and cloud infrastructure.
<About/>
I'm a full-stack engineer with over 8 years of experience designing, developing, and deploying complex software systems at scale. Currently serving as Tech Lead at Rexel Group, where I architect e-commerce solutions serving multiple international markets.
My expertise spans the entire development lifecycle – from system design and architecture to implementation, testing, and deployment. I specialize in building modern web applications with Angular, TypeScript, and microservices architecture, while leveraging cloud infrastructure to deliver high-performance, scalable solutions.
I'm passionate about operational excellence, mentoring junior developers, and continuously improving development practices through code reviews, testing strategies, and design patterns.
