    Hello, this is my profile! My name is Daniel, I am 30 years old, and I have been working in web development for five years. My journey with technology began early, at the age of 11. My first encounter with the web world was in a web designer course, where I learned HTML and the use of editing software such as Photoshop and Dreamweaver. Years later, at the age of 25, I returned to studying technology, seeking knowledge in JavaScript, HTML, and CSS. During this time, I had my first contact with NodeJs, React, and React Native. Today, besides being a technology enthusiast, I work as a full-stack developer at a major supermarket company in Paraná, working in various areas. I have a strong interest in DevOps and microservices.

    After developing a wide range of software and companies for 13 years, I am very secure when I say that dev is my passion. And in the last 5 years I figured out that what I do best in my work is to be able to translate in code and for the IT team, what a company needs to be done for its business.. I will explain. My first 7 years being a software developer were working mainly on retail companies like buscape.com.br, FControl (anti-fraud), Walmart Brazil, PRNewswire, submarinoviagens.com.br and impostometro.com.br. These years gave me a solid ground for performance goals because I had to always be looking for performance, scale, and clean code. At this time I also started managing small teams using scrum. In 2014 I started Polen.com.br, a corporate donation platform focused on offering ecommerces and companies an easy way to donate and practice CSR inside their business strategy, like donating part of their sales. This adventure led me to live in Santiago in Chile, London, and Manchester in the UK, where we got selected for different startup accelerator programs. In 2018 we went back to Brazil and after a pivot at Polen, we took our first investment round where R$700k was raised in total of venture capital initially focused on helping ecommerces to sell more using social impact as a differential and later by developing the first social impact open API in Latam for corporate donation. I have been Polen’s CEO for 2 years and after a strategy change, my partner took the job and I happily took the CTOs charge, which is my specialty. As CTO I was able to focus on building the technology in a way that it worked side by side with the whole business strategy for the company and being able to balance between clients and commercial demands and technology and infrastructure improvement. I implemented the agile framework that we work on now for the whole team, using OKR and Scrum to manage and measure results. It was a particular challenge when we decided to expand an IT knowledge framework for the whole team. It was a great accomplishment to see sales and support achieving greater results with an IT agile strategy. After Polen, I was able to work in a listed NASDAQ company as a Tech Lead in which I learned a lot and helped to implement new technologies and good Team leading processes. After OpenAI changed the game forever, I started to focus my career on helping companies optimize their processes using AI with my consulting company otimiza.ai. I'm also a mentor for new startups and entrepreneurs that are beginning their journey and with my 10 years experience with Polen, I can help on what to do and mainly what not to do. Besides being very proud of my professional life, I have to say that my greatest achievement happened in 2022. My little daughter was born and definitely is the best piece of organic hardware that I'll ever make!

    I am a web developer specialized in the JavaScript stack: - Typescript - React (Styled Components, Tailwind, Redux, Context) - Node - Next - NestJS I know a bit of Vue and Angular, but not (yet) in a professional level.
