About

Professional summary

I am a Frontend Developer with a formal Computer Science background from UNGS and over two years of experience building modern web applications. I specialize in React, Next.js, TypeScript, and creating polished, high-performance user interfaces.

I build scalable UI systems using component-based architectures, Tailwind CSS, SCSS, Storybook, and design systems. I care deeply about usability, visual consistency, accessibility, Core Web Vitals, and delivering responsive experiences across devices.

I have experience developing end-to-end SaaS products, including multi-tenant platforms, PWAs, POS interfaces, dashboards, and e-commerce storefronts. My work includes REST API integration, real-time data synchronization, offline-first functionality, and local caching with IndexedDB.

I also integrate AI and LLM-driven workflows into product development to accelerate delivery and improve team efficiency. I am comfortable working across frontend and full-stack contexts with Firebase, MongoDB, PostgreSQL, Node.js, and Java.

My background in software testing has strengthened my attention to detail, edge cases, regression prevention, and product resilience. I work effectively in Agile environments using Scrum and Kanban, collaborating through tools such as Jira and Git.

Career history

Full Stack Developer & AI Integrator Independent Contractor

I develop end-to-end SaaS platforms and web applications using Next.js, TypeScript, and Tailwind CSS, with a focus on user experience, maintainability, and Core Web Vitals.

I engineer offline-first caching layers with IndexedDB and Dexie.js to preserve operations during network interruptions and external API latency. I also integrate LLM-driven workflows that have reduced delivery times by more than 40%.

For MangoPoint, I developed a multi-tenant SaaS platform with a touch POS PWA and a real-time synchronized e-commerce storefront. The platform includes automated ARCA fiscal invoicing and offline checkout resilience.

For Auralis Web App, I built a bilingual creative-services platform with a dynamic full-stack gallery, optimized rendering, interactive particle effects, a custom magnetic cursor, and modular BEM-based SCSS.

Junior Frontend Developer Gincat Digital

I built modular React and TypeScript components for web products and documented the corporate design system in Storybook. This improved visual consistency and reduced duplicated implementation work across teams.

I consumed and integrated REST API endpoints to power management panels and interactive dashboards. I worked within Agile Scrum practices while contributing to maintainable frontend architecture.

Tester Accusys Technology

I designed and executed functional, integration, and regression test suites for mission-critical banking software. I also tracked, documented, and managed defects using Jira.

This role developed my preventative quality mindset and close attention to edge cases. I apply these testing principles to build more resilient and reliable frontend experiences.
