PROFILE
Nicolas Temciuc
Nicolás Temciuc worked on the cedarcode/mi_carrera repository, delivering a series of features and infrastructure improvements over ten months. He modernized the frontend with Tailwind CSS, standardized authentication flows, and upgraded core dependencies such as Rails and Devise to enhance maintainability and security. His work included building a modular scraping system in Ruby to provide accurate, current-semester subject data, and implementing Slack-based CI/CD alerting for operational reliability. By refactoring UI components, optimizing data management, and streamlining deployment with Docker, Nicolás ensured the codebase remained robust, scalable, and easy to maintain, demonstrating depth in Ruby on Rails and frontend development.

Feb 1, 2026February 2026 monthly summary for cedarcode/mi_carrera focusing on business value, reliability, and technical execution. Overview: - Re-centered data delivery on the current semester by delivering a user-facing feature to display current-semester subjects and aligning the UI with the current academic calendar. This reduces user confusion and improves data relevance for students planning coursework. Key achievements (top 5): - Display Current Semester Subjects feature delivered, including scraping current-semester subjects and UI updates to replace previous INCO-based data (commits: 82714f54..., 46bde247..., b6ccb34..., 3be2f603..., 3fa3e0b4...). - Introduced robust scraping workflow with modularization and improved maintainability (Refactor scraper; two-module architecture; updated rake tasks) (commits: 3be2f603..., 3fa3e0b4...). - Fixed semester threshold to ensure accurate subject data presentation (#992) (commit: b6ccb34...). - Infrastructure and tooling upgrades to boost reliability and reduce maintenance: Ruby 4.0.1, Bundler 4.0.6, headless Chrome window sizing, and removal of Rollbar (commits: 65e90601..., 93f9d451..., f41ba2f..., ba5822d...). - Performance and data freshness improvements: threaded scraping and on-the-fly current_period calculation, resulting in faster and more up-to-date subject lists (commits: 82714f54..., 3be2f603...). Impact and value: - Improved data accuracy and user trust by delivering current-semester subject data and clear notices on how data is obtained. - Reduced maintenance burden via modular scraper architecture, updated tasks, and removal of obsolete tooling. - Faster data refresh cycles and better scalability as the system grows to handle more degrees/semesters. Technologies/skills demonstrated: - Ruby on Rails, advanced scraping patterns, multi-threading, modular code design, and runtime performance tuning. - Dependency management (Bundler, Ruby version), headless browser configuration, and removal of legacy integrations (Rollbar). - Refactoring discipline, test cleanliness, and maintainability improvements.
