I'm working in a multi-tenant SaaS ERP platform for enterprise clients, designing the multi-tenant architecture and complex access control from scratch. I reduced client onboarding time from 2 weeks to 1 hour through an AI-powered tax invoice parser that auto-populates catalogs and initial data. I designed and built a pricing module with automated recurring billing and subscription management. I also developed complex ERP modules including bank reconciliation, document management, real estate tracking, and investment portfolio tools. I mentored junior developers and guided them through the team's core development workflow.

2023 — Present: I design and operate end-to-end software solutions for the business, including an ERP and POS system built from scratch that supports atomic transactions for multi-store inventory management, with multilingual support (ES, EN, KO) and continuous integration and deployment pipelines. 2018 — 2023: I managed the company's website, modifying styles and visual components of the system. I also handled the company's accounting information and warehouse control.

I developed an internal messaging broadcast platform from scratch, enabling secure mass communication for employee networks. I built a custom authentication system with phone verification, implementing rate limiting to avoid provider bans while processing thousands of messages daily with zero downtime.

I developed 'FixHogar', a home services marketplace with three mobile apps (Client, Expert, Admin). I designed a scalable REST API handling 5,000+ daily requests and managing user profiles, service bookings, and ratings. I implemented real-time notifications and payment gateway integration.
