Senior Full Stack Engineer

I build scalable, maintainable, and high-performance frontend applications using Vue 3 and Nuxt. My work follows Clean Code and SOLID principles and focuses on delivering production-ready software.

I collaborate in Agile teams using Azure DevOps for backlog management, sprint planning, and delivery tracking. I also work with Azure services, pipelines, releases, repositories, ARM templates, accessibility standards, SEO improvements, Datadog, and LaunchDarkly.

I delivered end-to-end Web3 and NFT solutions across multiple projects, including smart contract development, frontend and backend engineering, ecosystem automation, and community tooling. I developed ERC721A contracts with advanced sale mechanics, NFT collections, ERC20 tokens, and passive staking functionality.

I built React and Vue.js applications, Discord bots for transaction monitoring and community engagement, NFT combat-game features, rarity tools, and marketplace integrations. Technologies included Solidity, Node.js, MySQL, DigitalOcean, Moralis SDK, Web3.js, and OpenSea, LooksRare, and X2Y2 APIs.

I led frontend, backend, and smart contract initiatives for Web3 and NFT products. I built the responsive React and Next.js frontend for the Messi Time Machine NFT project and developed a full-stack NFT platform for a World Cup bracket challenge with purchasing, predictions, and real-time interactions.

I maintained and optimized the main React and Next.js platform, developed Node.js and NestJS backend services, and created Solidity smart contracts deployed through Hardhat. I also delivered blockchain proof-of-concepts using Algorand and Ripple for NFT minting, trading, and marketplace expansion.

I maintained legacy systems and supported their migration to a modern PHP architecture using Symfony, improving reliability and scalability. I developed backend services, internal tools, and event-driven components for internal teams.

I strengthened application security by implementing a web application firewall with Nginx and ModSecurity to mitigate XSS and other web vulnerabilities. I also improved delivery workflows with Docker, contributed React frontend integrations, and worked on Java-based system components.

I developed and enhanced digital solutions for self-service systems, cashless payments, ticketing, accreditation, and access control. I created the ElevenCash cashless application using Java for Android, Vue.js for the frontend, and PHP backend services.

I built self-service systems for reload cards and cashless wristbands, REST APIs for self-service terminals, and integrations for facial recognition and ThermoFocus temperature-measurement devices. I also supported access-control systems at major stadiums and events, including Copa America 2019.

I developed and maintained internal web systems focused on intranet functionality, reporting, and operational support. I designed dynamic reports and interactive pages that improved access to business information and supported decision-making.

I implemented backend and frontend features using PHP, SQL, JavaScript, HTML, and XML. My work improved usability, performance, and data presentation across internal platforms.
