My Experience

Companies I’ve had the opportunity to grow with, build products for, and solve real-world problems.

Acelerios

Full Stack Developer

June 2025 - Present

I’m part of a startup building BuildRunKit, a SaaS platform that helps small business owners with strategy, marketing, and branding. Since joining, I’ve led the frontend development from scratch, creating a production-ready landing page with React, Vite, and Tailwind CSS, including theme switching, multi-language support, and several AI-powered tools (business name generator, slogan creator, QR/Invoice tools, etc.). I also built the platform’s authentication system, contributed to its core features, and rebuilt a non-functional CRM product, handling its auth, database integration, and landing page. In just three months, I’ve helped take the company’s frontend from an empty repo to a live, production-ready platform.

About Me

Hey! I’m Saul Maldonado Navarro, a 25 y/o Computer Science Engineer and full-stack developer from Tlaxcala, Mexico. I specialize in building clean, efficient, and maintainable web applications using technologies like React, Node.js, TypeScript, and MySQL.

My journey into software development started with curiosity and turned into a career — from intern to full-time developer, working on a SaaS platforms and helping ship features that solve real problems. I also have experience with tests like unit, E2E and regression, authentication, dashboards, and CI/CD pipelines — always aiming to write code that’s both thoughtful and useful. I believe in team work, clear communication, and continuous improvement and learning.

Outside of work, I’m passionate about mountain biking 🚵‍♂️, hiking, take a walk with my dogs, play Monster Hunter and discover new music.

Hellow :)
