With experience in Frontend & Backend Development, as well as DevOps basics. I love structuring and constantly improving my code, collaborating with other people and participating in brainstorming sessions.

I value innovative content & structure, clean design patterns & code, and thoughtful & respectful interactions.

</AboutMe>

Hi! My name is Patrícia Costa da Cruz. I'm a freelance Full Stack Software Developer. My interest in Development started in 2021 when I decided to upskill myself and enter the tech world. I love to work on backend projects because of their complexity but I also like frontend challenges! Using different technologies and tools, I'm able to create efficient and scalable solutions.


My main focus these days is applying best practices & coding as much as I can, I like to work on side projects which are different from my day-to-day job, and I really enjoy learning from knowledgeable people around me.

Biosaï

Biosaï is a prompt engineering tool that lets users get immediate value for predefined use cases. When users selects a preset, they go through a predefined set of questions. The answers are treated as inputs to create a final prompt which is then sent to the relevant AI engine to generate a response, and return it to the users.
I joined Biosaï's team as I believe in its potential and I am really interested in the technologies used. I briefly worked on the project early-on in 2023, and have come back later in 2024 in order to assist developing and improving this amazing tool. I am currently the main developer and one of the three co-founders.
