Norberto Enrique Cáceres Cárdenas

Developed the MVP for the VirtuVision product: https://virtuvision.vercel.app. VirtuVision is an AI-powered learning platform.

• Worked with Python and Langchain to create a PDF analysis tool.

• Set the foundation for the back-end project in terms of technology stack and code structure.
• Was the main coder of the back-end project.
• Set a test-driven approach to development.
• Was pro-active in making business logic decisions in terms of edge-cases as the client's product was in a very early start-up stage so the product specification was not exhaustive.

• Contributed to the design of Nest.js + RabbitMQ + MQTT based microservices, using PostgreSQL and Redis as the persistence layers. I've also contributed to the development of frontend applications using React.
• Developed an initial developer guide explaining some of the technical challenges we were going to face by building a microservices-based architecture, and outlined some strategies and techniques to solve them.
• Proposed Redis as the primary database for the core service in charge of pairing demand (orders) with supply (bots & pilots). This proved to be a big win not only in performance but in the wider choice of data structures Redis provides.
• Conceptualized the core service as a Finite-State-Machine (FSM) with independent nodes (FSM states) that consume priority queues. This architecture/mental-model proved easy to scale, both physically and mentally for developers.

• Contributed to the maintenance of a legacy Sails.js + MongoDB application.
• Developed a proof-of-concept for an improved scheduled payment mechanism.
• Resolved long-standing bugs in the codebase and refactored aspects of it, improving readability significantly.

• Contributed to the frontend development of the bank's p2p transactions app.
• Contributed to the design of MySQL schemas for the bank's p2p transactions app.
• Held weekly meetings with pertinent team members where we discussed and groomed the next sprint's tasks.

• Developed an MVP of a national budget transparency system for a Panamanian government agency.
• Managed two developers, one front-end and one back-end.
• Presented the project to pertinent members of the organization and our proposal was regarded as promising and ambitious.

• Developed a Shopify React plugin that allowed customers to keep track of their loyalty points and redeem them as discounts for their purchases.
• Fixed bugs and refactored parts of the core node.js application.
• Fixed bugs and refactored parts of the core vanilla HTML + CSS frontend application.

• Developed and internal tool for keeping time-series aggregations of sales data using node.js, MongoDB and React.
• Configured a Firebase project and integrated Google Analytics into the web app.
• Fixed bugs and refactored parts of the core vanilla HTML + CSS frontend application.
