Bryan Gomes Saraiva
Founder, Full-Stack Developer, and Product Architect
I am a software developer with a proven history of building, launching, and scaling products from zero to millions of users, single-handedly. My work, spanning mobile apps, complex game modifications, and a full-featured SaaS platform, demonstrates a rare combination of technical mastery, user-centric design, and an entrepreneurial spirit. I don't just build features; I build empires.
By the Numbers: A Career at a Glance
These are not team accomplishments. This is the impact I have delivered alone, without funding or external support.

My Journey: From Solo App Developer to Platform Architect
My career has been a strategic progression, with each step building on the last to create a uniquely versatile skill set.
Phase 1: Conquering the Mobile Market
I began my journey by diving headfirst into the Android ecosystem, independently developing and managing a portfolio of over 12 applications. This is where I learned to build complete products from concept to launch. I engineered viral hits like "Roller Roulette", which amassed over 2.3 million installs by focusing on performance for low-end devices and implementing custom multi-language support to unlock international markets. This phase proved my ability to manage the entire product lifecycle—from development to marketing and monetization on a global scale—and established my foundation for building user-centric software.
Phase 2: Mastering a Craft in the Trenches
With a strong product background, I shifted my focus to the highly competitive world of game modding to deepen my technical expertise. I used LUA and C++ to reverse-engineer complex game systems and build features the original developers hadn't. Publishing over 200 mods taught me how to write highly efficient, stable code under extreme constraints. This work, including community-defining mods with 4M+ individual downloads, established my reputation for technical excellence and innovation, proving I could deconstruct and master any system put in front of me.
Phase 3: The Founder's Gauntlet — Cartovyn
The culmination of my experience is Cartovyn, a sophisticated SaaS platform for the tabletop role-playing community. As the sole architect and developer, I built this entire full-stack application from the ground up. From its performant Next.js frontend to the robust Supabase/PostgreSQL backend, every line of code, every API endpoint, and every architectural decision was my own. Launching a complex, market-ready platform single-handedly demonstrates my capability to execute projects of the highest order, blending advanced engineering with strategic product vision.
As a recent graduate with a Bachelor of Information Systems, I have now paired my seven years of intensive, real-world experience with a strong academic foundation. I am a native Portuguese speaker, fluent in English, and ready to apply my unique background to solve the next significant challenge.
I'll let the next project speak for itself.
