Project history
Backend Developer focused on designing, developing, and maintaining scalable backend services and APIs. Collaborating with a distributed team to build reliable software solutions while following engineering best practices.
• Develop backend services using Node.js, NestJS, and TypeScript.
• Design REST APIs and integrate with PostgreSQL and Redis.
• Deploy and maintain cloud infrastructure on AWS.
• Participate in architecture discussions and code reviews.
• Collaborate in an Agile development environment.
Company Description: A leading financial technology company in South America, managing the complete Acapuedo Fintech Ecosystem, including the core payment processing API and the administrative frontend.
Engineered and maintained both the backend API (Laravel 10) and the frontend admin UI (Blade/Livewire) for a comprehensive fintech platform handling payments, transactions, and merchant management; developed core backend services such as BalanceService and CashoutService and integrated 70+ external payment and telecom providers using a custom factory pattern to ensure robust financial operations; built the admin interface with dynamic data tables and charts (DataTables, Chart.js) to enable efficient management of merchants, users, and financial reports; designed a custom PDO-based database layer to replace Eloquent ORM, optimizing MySQL queries for high-volume financial transactions; implemented secure token-based authentication (JWT) for the API and role-based access control (admin/sales) for the frontend; maintained high code quality through static analysis (PHPStan) and extensive unit and feature testing (PHPUnit); and collaborated in an Agile environment, contributing to all stages of the software development lifecycle from requirements gathering to deployment.
Technical Environment: Laravel 10, PHP 8.1+, MySQL, Livewire 2.5, Blade, Bootstrap 4, jQuery, DataTables, Git, PHPUnit, PHPStan, JWT, REST APIs.
As a developer, I collaborated on the transformation of Universidad del Pacífico's digital infrastructure by designing and implementing two interconnected systems. The first is an Academic Management System built with Python, Django, and PostgreSQL, serving as the institutional backbone for all core academic operations—including student enrollment, course management, grade processing, and regulatory compliance. This system handles over 10,000 daily transactions with exceptional reliability, replacing outdated legacy systems and reducing administrative workload by nearly half.
To complement this system, I developed a modern Campus Portal Ecosystem using the PERN stack (PostgreSQL, Express.js, React, Node.js), delivering responsive, user-friendly interfaces for students, faculty, and administrators. The portal features real-time grade tracking, interactive course dashboards, and automated reporting tools, all securely connected to the main academic system via RESTful APIs and WebSocket connections. The React-based frontend, styled with Bootstrap, ensures a consistent, mobile-ready experience across all devices.
Key technologies: Pythoan, Django, PostgreSQL, JavaScript, React, Node.js, RESTful APIs, WebSockets, Bootstrap, Docker.
