    Work

    Software engineer - Tech Lead

    Consumidor Positivo/Acordo Certo

    Feb 2023 - Currently

    I'm currently a tech lead at Consumidor Positivo, a joint venture between Red Ventures and Equifax, formed by merging the IQ and Acordo Certo teams. The business focuses on debt renegotiation, credit products, and services related to credit scores. While my main expertise remains in front-end development, I now work in a more generalist role—contributing to back-end, CI, team management, and people development. I continue to drive creative tech solutions, leading the development of internal tools that bring together people with diverse skill sets to solve everyday challenges.

    Red Ventures

    Oct 2019 - Oct 2023

    I worked in a dedicated team called IQ Contas, focused on automating utility bill payments. I joined as a junior developer and grew into a senior role, working mainly with React, React Native, and AWS. Over time, I also contributed to back-end development with Golang and serverless. I led the creation of internal tools like Blueberry (our design system) and Firebolt (a multi-step form builder), bringing more creativity and an collaborative mindset to the team.

    Apr 2019 - Sep 2019

    In my first experience working in a team, I joined LEDI, a company focused on access control solutions and automation of internal workflows for other organizations. My work was primarily front-end development with Angular, but also involved maintaining legacy systems built with jQuery. I also contributed to UI design using Adobe XD and occasionally handled back-end tasks using PHP with Laravel.

    I started my journey in technology as a freelancer, working mainly with JavaScript, PHP, and WordPress while learning more modern technologies like React and Vue. I also worked with jQuery, CoffeeScript, and mobile development tools such as Apache Cordova and Ionic. Additionally, I dabbled in web design/UX.
