About Alejandro

Hello! I'm Alejandro, a Senior Front End Engineer with 4 years of experience transforming complex ideas into high-performance digital products. My specialty is the React.js and Next.js ecosystem, where I focus on creating intuitive, scalable interfaces with impeccable TypeScript code.

How do I add value to your projects?
• Web Accessibility (WCAG): I have real experience implementing standards for AA certifications, ensuring the product is inclusive and complies with current legal regulations.

• Technical Efficiency: I master modern tools like Tailwind CSS for rapid deliveries without sacrificing visual quality (Pixel-perfect).

• Optimized Performance: I ensure your application is fast and meets the best Core Web Vitals standards.

• Fluid Collaboration: I accurately interpret Figma flows and easily integrate into agile teams, contributing a senior technical vision that avoids future errors.

I have worked in various corporate sectors, which gives me the ability to quickly understand business objectives and translate them into solid technical solutions. If you are looking for a committed collaborator who pays attention to detail and delivers expert-level results, I will be happy to help you take your project to the next level.
