I build high-performance web applications using modern technologies and efficient runtimes. Focused on clean code and intuitive user interfaces.

Portrait of the developer in a high-contrast style
Background

Engineering web apps that scale and interfaces that perform.

I am a Full-Stack Developer who is passionate about building robust software. I focus on writing clean, maintainable code and developing resilient applications that solve real problems while maintaining an uncompromising standard for user experience.

My expertise lies in bridging the gap between efficient backend logic and dynamic frontend ecosystems. I am continuously learning and building for performance, scalability, and maintainability.

01 // Systems Design

Developing real-time applications and seamless full-stack data flows.

02 // Modern Frontend

Building modern, reactive user interfaces with React, Next.js, and high-performance tooling.

03 // Runtime & Infra

Creating efficient backend services using Node.js, Bun, and containerized deployments.

04 // Quality Culture

Dedicated to clean code, SOLID principles, and reliable testing practices.

Core
Principles

The dogmas that govern every line of code and every architectural decision I make.

01

S.O.L.I.D over Convenience

I prioritize long-term maintainability over temporary shortcuts. Clean code is the only path to scalability.

02

Performance by Design

Performance is not a post-optimization; it is an architectural foundation. Every ms counts in the user experience.

03

Resilient Architecture

I design systems that fail gracefully. Technical robustness comes from anticipating error and mitigating its impact.

Projects
& infrastructure

A selection of full-stack applications built with performance and clean code in mind.

Luxe Estate

"Redefining the digital luxury real estate experience. Luxe Estate combines cinematic visualization with a robust infrastructure based on Server Components and Server Actions for exceptional performance."

Next.js 16 Supabase Tailwind CSS 4 Leaflet i18n

Assembly: Endgame

"A high-stakes word-guessing survival game built with React 19. Players rescue iconic programming languages through dynamic state management and full ARIA accessibility."

React 19 CSS Grid ARIA Hooks

Tickets App

"High-efficiency real-time flow architecture. The ecosystem bridges React 19 with native WebSockets and a Bun/TypeScript backend for instant reactivity."
