Bryant Caballero
Senior Full Stack Developer
4+ years building web and mobile products with React, Node.js, and TypeScript. I like boring code: clear standards, automated checks, and releases nobody is scared of. Now I want to bring that to a secure development role.

Experience
Semi-Senior Full Stack Developer · Baleares Group
May 2022 – Oct 2026
- Worked on JAD, the internal platform behind 8+ client products, and owned a big part of it: authentication and permissions, keeping each client's data separate, and automated tests.
- Integrated payments with Stripe and Mercado Pago, and electronic invoicing with ARCA (Argentina).
- Built the internal quality modules that keep the code to standard. When the team started coding with AI, I wrote the rules that code had to follow.
- Owned DevOps: per-environment seeds and migrations, and CI quality gates that blocked a deploy if anything failed.
- Migrated all 6 client legacy systems onto JAD in under a month and moved the infrastructure from virtual machines to Cloud Run.

I'm working through Hack The Box's Junior Cybersecurity Analyst path and studying application security (OWASP Top 10) to bring what I already did with permissions and CI checks into a secure development role.
