I build software that shipsand stays standing.
Today I lead IntelliFix, an Industry 4.0 platform at SMI. From front-end to deploy — through IoT, real-time data, and command-line tooling.

Experience
Technical Lead — IntelliFix
I lead the technical development of the IntelliFix platform: new features, architecture, and performance. I joined as a junior, became a full-stack mid-level dev in two months, and reached technical lead in under a year, serving large global industrial companies.
- —From junior to technical lead in under 1 year
- —Technical leadership of the dev team
- —Scalable architectures for enterprise clients
- —Platform performance optimization
- —Mentoring and technical reference for the team
Frontend Developer
I joined as the sole front-end dev on a legacy Angular.js system — inconsistent layout, poor performance. After a technical review, I proposed and executed a full refactor to Next.js 14, modernizing the whole front-end architecture.
- —Full refactor from Angular.js to Next.js 14
- —International expansion: global SIM and eSIM sales
- —Sales lift through better UX/UI
- —Major gains in performance and scale
- —Implemented a consistent design system
Junior Frontend Developer
I built web experiences focused on Next.js and SEO, and occasionally worked on the back-end — which broadened my full-stack view.
- —Responsive interfaces with SEO focus
- —Landing pages for client acquisition
- —Node.js API optimization
- —More efficient database queries
- —Increased search-engine visibility
About
I'm a full-stack developer. I started coding in 2020 and, at SMI, went from junior to technical lead in under a year — today I drive the development of IntelliFix, an Industry 4.0 platform used by global companies.
I like hard problems: real-time data, factory-floor integration, refactoring legacy, command-line tooling. I write from front-end to deploy, and I care about what happens after the code ships — performance, maintenance, and the next dev who'll touch it.
