Julian Hernandez

'm an Information Technology Engineer (Universidad AUNAR, 2024) and Full Stack Developer focused on solving real business problems through well-designed software: fewer manual errors, faster processes, and systems that scale.

For nearly 4 years as Senior Full Stack Developer and Technical Lead at Agencia DROI, I led — using Agile/Scrum methodologies — the development of a corporate access control system used by over 200 daily employees, a bidirectional integration with the SIIGO ERP that eliminated 100% of manual accounting data entry (cutting errors by 90%), and a scheduling system for over 50 simultaneous sessions that reduced calendar conflicts by 60%. I also normalized the database of a corporate parking system, improving SQL performance by 50% and eliminating all data redundancy.

Alongside that, since 2021 I've worked as a freelance developer building an end-to-end PMS (Property Management System) for real-time hotel management — reservations, rooms, and reports — with a decoupled TypeScript architecture capable of supporting up to 500 simultaneous reservations. I automated 100% of the billing and voucher distribution process via the WhatsApp Business API and email, cutting the team's administrative time by 70%, and implemented transactional logic to guarantee data integrity in giveaways with over 1,000 participants.

I'm currently a Senior Full Stack Developer at Consuerte, refactoring the Autofile platform and improving how agreements are queried, invoices are uploaded, and reports are generated by 80%.

I work with Next.js, React, Nest.js, TypeScript, PHP, Laravel, Docker, Git, and GitLab. I'm especially interested in scalable system architecture, automating complex business processes, and database optimization. I'm a native Spanish speaker with B2-level English.
