Hi, my name is Bruno.
Here’s a quick summary of my main journey so far as a professional developer.



## 1st trajectory — Ruby on Rails


**Stacks:** Ruby on Rails · Next.js · Flutter  
**Infra:** transition from Heroku → AWS


- Started my career in a structured Agile SCRUM team (QA, PO, Scrum Master, Tech Lead), contributing as a trainee to sprint delivery and agile planning.


- After one year in that team, I transitioned to independently maintaining and evolving a Ruby on Rails product, taking full-stack ownership of a healthcare platform.


- Recently migrated this production Ruby on Rails server from Heroku to AWS, improving performance and reducing costs. Configured RDS, S3 buckets, Amplify, SSL/TLS, and managed domains using cPanel on AWS.


- Built a Flutter app from scratch and deployed it to the Google Play Store; it is currently used by clients for real-time server communication.


- I’m also developing and maintaining the API that serves both the Flutter mobile app and the Next.js frontend.


- Currently implementing a new Next.js frontend based on a commercial Bootstrap design, fully integrated with the RoR API.


- Also currently integrating medical equipment into the Ruby on Rails-based healthcare system, enabling real-time monitoring and clinical data synchronization.



## 2nd trajectory — Django / DRF


**Stacks:** Django · React · React Native · Web3 · AWS


- Coordinated a small dev team to build a complete system from scratch using React, Django, and React Native, with push notification support triggered by backend events. The product was later extended with blockchain integration.


- Rejoined the same blockchain-based project as IT Manager; currently leading a small team working on smart contract integration and system maintenance.



## Overall context


All of my professional development experience has been in startup environments: fast iterations, MVP delivery, and full-stack product responsibilities.


Before becoming a developer, I worked as an English teacher.
