Programmer since I was 14 years old, I am now 38, and have been 24 years coding

Currently I work with website development, apps, and process automation, and machine software using Arduino or Raspberry

I have solid knowledge in some Artificial Intelligence learning algorithms, and I've been working in the background on a 2D game in C++

I love Arduino, C++ is my favorite language. I like strongly typed languages and clean code, with explicit functions, microservices, well documented and organized.

I take on many types of development work, and I'm always open to a good proposal 😉😎

SmartBot

SmartBot is an AI-powered Discord bot I created for the Tecnologia da Informação BR server. It answers members' questions about the community's rules, channels, and open-source projects, helping keep the server active and organized.

The bot uses a large language model (LLM) accessed through the Groq API. I provide the model with a knowledge base containing server rules, channels, moderators, and projects, along with instructions on how to behave: respond in Portuguese, be direct, avoid making up information, and remain silent when a conversation is not directed at it.

Before making an AI API call, the bot determines whether it should respond. It only answers when mentioned, when someone asks a question in designated channels, or when a keyword is used. Dynamic information, such as the time, date, and Bitcoin price, is supplied by the code using real values rather than relying on the model to guess.

It also runs automated tasks. At scheduled times, it posts a creative good-morning message in the general chat, promotes open-source projects with varied messages, and posts a meme in the meme channel, once per day for each task, with execution tracking handled by SQLite. If an API key reaches its usage limit, the bot automatically switches to the next one.

Moderation deliberately does not rely on AI. Instead, it uses predictable, rule-based logic. The bot deletes prohibited words and targeted insults, mutes the author, logs all actions in a dedicated channel, and bans users who enter an anti-spam trap channel. Trusted roles are exempt from these rules.

This is an open-source project released under the MIT License and is still under development. Planned features include conversation memory, semantic search, conversation summaries, and a knowledge base that learns from answers approved by administrators.

Modular architecture with separate event handlers, services, and utilities. Channels, API keys, and word lists are configured outside the source code.

Technologies used: Python, discord.py, Groq API (gpt-oss-120b model), SQLite, python-dotenv, and the CoinGecko API.
