Hi, I'm Arancha!
About me
Driven Full-Stack Developer and recent BSc Computer Science Graduate (First Class Honours) with 1.5+ years of commercial experience building performant web applications with React, TypeScript, and Node.js. I like building things that actually work: clean, fast, and useful to the people using them.
Outside of my core responsibilities, I've always been drawn to understanding the whole system, I like to go beyond my role sometimes just because I want to know how things fit together. That curiosity is what I bring to every team.
I get excited about roles where there's room to grow beyond a narrow job specifications. Contributing to product decisions, picking up new technologies, and working closely with a team that cares about what they're building.

PROJECTS
Overview
A full-stack community platform connecting disaster-affected communities with qualified first responders.
Problem solved
Developed in response to the lack of coordination tools during disasters, particularly highlighted by the 2024 Valencia floods where communication between volunteers and those needing assistance was severely limited.
Results
Awarded a distinction and selected to showcase at the 2025 Oxford Brookes Tech Show, generating significant interest from attendees and faculty.
Overview
A complete website redesign for a kitchen company featuring an interactive kitchen customization tool.
Problem solved
Modernized an outdated website to improve performance and user experience, helping attract new clients through better functionality and visual appeal.
Results
Delivered significant performance improvements and client growth. Continues to be maintained with regular updates, receiving highly positive user feedback particularly for the interactive kitchen visualization feature.
Overview
A data analysis project investigating water reservoir trends in Madrid through ETL and predictive modeling.
Problem solved
Explored the relationship between climate patterns and reservoir levels through comprehensive data analysis, testing the hypothesis that increased rainfall was driving higher water reserves.
Results
Analysis revealed that improvements in water management and conservation technology, rather than climate change, were the primary drivers of increasing reservoir levels, challenging initial assumptions.
Overview
A Python automation tool that generates complete React project scaffolding through an intuitive GUI.
Problem solved
Eliminated repetitive 3-hour project initialization workflows by automating folder structure creation, component generation with base code, theme configuration, and icon componentization.
Results
Reduced project setup time from 3 hours to 15 minutes. Adopted by the entire frontend engineering team (3 engineers), receiving enthusiastic feedback for significantly improving workflow efficiency.
Overview
An internal password management system with role-based access control and encryption.
Problem solved
Addressed critical security vulnerabilities where sensitive passwords, including CEO and HR credentials, were shared via Slack conversations accessible to unauthorized employees and even former staff after termination.
Results
Successfully adopted company-wide (12 employees) with full engineering team rollout followed by organization-wide implementation. Eliminated password loss incidents and security breaches, remaining in active use throughout tenure.
