During September 2025, Christian Hernández developed and enhanced voting and administration features for the IngAlim2023/sigevaFront and sigevaBack repositories. He implemented a user authentication system, OTP-based voting flow, and a real-time dashboard for election metrics, focusing on scalable, compliant operations. Using JavaScript, TypeScript, and AdonisJS, he integrated dynamic data retrieval, Excel-based data uploads, and robust access controls. On the backend, he modeled voting data, enforced voting restrictions via middleware, and refined API endpoints for elections and candidates. His work demonstrated depth in both frontend and backend engineering, addressing real-time data needs, security, and usability across the voting platform.
