TRABEL BI — Travel analytics for corporate clients

Context

TRABEL BI is an analytics product built by Negocios Nex for corporate travel customers around the world. I worked as Frontend Developer and Data Analyst on a Nuxt.js + Vue.js codebase backed by a Node.js API.

This is closed-source proprietary work for an employer. The notes below describe my contributions at a technical level — no production screenshots, code or customer data are shared.

My role

• Built advanced reports with interactive charts and dynamic tables on a Nuxt.js + Vue.js frontend.
• Shipped entire modules from scratch by reusing production components through configurable flags, avoiding duplicated logic across similar flows.
• Led a progressive migration of table libraries to more performant, modern alternatives — preserving existing modals and custom features along the way.

Highlights

• Backend bug triage: resolved complex performance and data-integrity bugs in the Node.js backend — including refactoring functions that returned inconsistent payloads and applying safe SQL-rewrite patterns at scale.
• Roles & permissions module: built the user module with granular access control and per-profile feature toggles.
• APIs: designed and consumed RESTful endpoints for real-time data processing.
• Cross-functional: worked with Product Manager to capture requirements and shape features, keeping deliveries aligned with product goals.
