• Agenda360.app — Architected and developed the full backend platform (Django, PostgreSQL, Redis), centralizing schedule management for the business's client base and cutting manual administrative work by an estimated 70–80%. • Designed and integrated REST APIs with the Mercado Pago API to automate end-to-end payment processing, eliminating manual reconciliation from the transactional flow. • Engineered a decoupled task-queue system with Redis and RQ to move long-running jobs off the main request thread, improving response times and allowing the app to scale under load. • Modeled and optimized relational databases (PostgreSQL, MySQL, SQLite) and streamlined complex queries via the SQLAlchemy ORM to ensure data integrity and fast reads at scale. • La Arena VL — Built a web system for activity and user management from scratch (Flask, SQLite, SQLAlchemy), including role-based access control and data administration tooling. • Panchadata & Stickids — Delivered backend applications for data management, automated reporting, and business-logic integration using Laravel and PHP. • Standardized deployment across Linux/Docker on GCP, AWS, and VPS environments, improving release reliability and infrastructure consistency across projects.

• Built a foundation in organization, client communication, and cross-team coordination that now underpins a structured, requirements-first approach to software delivery.
