Within the scope of this role, my responsibilities included developing new features, fixing bugs and improving the performance of the application and Internet Banking of the IRIOM digital bank.Among the notable deliveries made was the "refer and win" program for the application. In this delivery I had to program in native code for both Android and iOS, to enable the storage and retrieval of referral codes after and before the user installs the store app.Another significant task was the functionality of non-nominal cards. This functionality aimed to expand Iriom's reach among truck drivers, distributing non-nominal cards at gas stations as part of marketing campaigns. These cards allowed users to experience the benefits of using IRIOM without having to order a card and wait for it to arrive.I implemented this functionality in the mobile application. I developed the entire card registration flow process, including requesting a duplicate card and generating virtual cards.

After 7 months as a full-time Full Stack Developer, I was promoted to Technical Leader of the B2B squad. With increased responsibilities, I focused on documentation, onboarding new developers, conducting code reviews, and monitoring system metrics.During this period, I handled debugging, feature development, and technical feasibility analysis for the squad. I also estimated tasks, collaborated on business rule documentation, supported PM and PD teams in discovery, and ensured code quality through automated testing.

After a successful 3-month stint as an intern, I was promoted to work as a full-time Full Stack Developer in the B2B squad. With increased responsibilities, I began conducting technical feasibility analyses of activities, ensuring code quality, developing automated tests, and building microservices using AWS tools such as Lambda, S3, SQS, and API Gateway. Additionally, I assisted in defining the squad's OKRs and KPIs.During this period, my main responsibilities included debugging and developing new features for the squad, assisting in technical feasibility analyses of proposed activities. I also participated in task estimation and development structure definition, collaborating on determining and documenting business rules. Furthermore, I supported the Product Management (PM) and Product Discovery (PD) teams, as needed, in the discovery process, and ensured the quality of codes used in the product by developing automated tests for implemented features.

During my last year in high school, I was recommended by a professor to work at Arbo Imóveis as an intern. I was involved in bug fixing, feature development, and writing and documenting business rules. During the internship, I worked with Next.js, Loopback.io, Node.js, PostgresSQL, Angular.js, and React Native.

I participated again in the PIBIC-EM program with the project "Alcoholic and Acetic Fermentation of Tamarind Pulp" in the development of the work "Development of a Remote Temperature Control System for the Fermentation Process" under the guidance of Professor Dr. Lyssa Setsuko Sakanaka from the Federal Technological University of Paraná (UTFPR).During the program, I aimed to build a system responsible for automating temperature control, using two low-cost reservoirs, one for cold water and one for hot water, which would be controlled by the ESP32 microcontroller. This allowed for greater control over the fermentation process, reducing the loss of quality in the final product due to temperature variations, and provided remote control and data visualization through a mobile application developed with the Flutter framework.

The Institutional Program for Scientific Initiation Scholarships for High School Students (PIBIC-EM) aims to strengthen the process of disseminating basic scientific and technological information and knowledge, and to develop the attitudes, skills, and values necessary for the scientific and technological education of students.I participated in the program with the project "Alcoholic and Acetic Fermentation of Tamarind Pulp" under the guidance of Professor Dr. Lyssa Setsuko Sakanaka from the Federal Technological University of Paraná (UTFPR).During the program, I had my first contact with the scientific community. I was able to understand how scientific research is developed, familiarize myself with scientific articles, conferences, and technical-scientific writing.The final result achieved with this project was that for the development of a temperature control system for a laboratory fermenter, using Peltier cells for water cooling is a better cost-effective option compared to other methods. Due to the lower cost and energy consumption of Peltier cells, it will be necessary to increase the time in which the water can be cooled, making the use of Peltier cells more viable for the project.With this conclusion, it was possible to continue the project the following year with the development of the temperature control system.
