SWE Portfolio

This is a list of projects I’ve created or worked on as a Software Engineer.

Personal project for fun. A database of movies with the sole purpose of warning you about jumpscares in movies (community-based), including timestamps and intensity level. Project is being developed with backend APIs in PHP Laravel and frontend in React (mainly using AIs, because I’m not a good frontend developer), and still have some fixes to be made before loading the full dataset of movies into it.

Instaprime for Survey Brasil

2019 - 2021

An innovative idea: paid private profiles on Instagram. The software would automatically accept or refuse followers in a private profile in IG based on whether the user’s subscription is active or not. The project was successfully ran with one of the biggest finance creators in Brazil (Ações Garantem o Futuro), generating a steady $1M MRR for them. Later on IG itself implemented the feature of paid profiles.

Linkzap for Survey Brasil

2019 - 2020

A software that automatically sorted WhatsApp groups for new members: if a group is full and a user is trying to enter, it automatically creates a new group and send the user to that new group. This software was used for marketing launch strategies that used WhatsApp as the primary source of communication. I worked on the backend whereas a coworker developed the frontend.

Tools: PHP, Laravel, MySQL, React, Github, WhatsApp API

Helo

AI Chatbot for Survey Brasil

2018 - 2020

Helo, a Customer Support Chatbot using IBM Watson’s conversational AI. The bot handled more than 60% of the chats at its peak by helping customers with simple questions or basic tasks, which were the majority of the requests we received. The bot was integrated with a webpage chat and WhatsApp’s API - the latter using a middle man partner, as WA’s APIs at the time were very basic. The chatbot’s AI was made using IBM Watson’s capabilites, and Python was used to make some integrations with backend APIs. I developed the chatbot from ground up and even participated in the Bradesco’s AI Congresses (BIA - Bradesco Inteligência Artificial) at the time to get along with AI.

Tools: AWS EC2, AWS SQS, Python, IBM Watson, Github, WhatsApp API
