As the CTO and founder of a dynamic early-stage startup, I have been responsible for overseeing the end-to-end development and strategic evolution of our core product and business.Key responsibilities include:- Leading the design, creation, and continuous improvement of the MVP.- Defining and implementing the product and company growth strategy.- Hands-on involvement in the full development lifecycle, including front-end (Svelte), back-end (Node.js, Python), database management (PostgreSQL), and DevOps (Google Cloud).- Managing freelance teams to ensure project success and efficiency.- Collaborating with co-founders on business and strategic decisions.- Engaging with key clients, participating in presentations, and developing follow-up materials to ensure client success.- Architecting scalable solutions, leveraging cutting-edge technologies.- Developing solutions with Generative AI technologies, including LangChain, LLMs, Speech-to-Text, Vector Databases, and more.Driven by innovation and technical excellence, my focus is on delivering value through scalable and impactful tech solutions.

As a Engineering Director, I was responsible for all engineering teams in the company – about 100 direct or indirect employees – divided into four main areas:- SaaS: multifunctional product squads developing our main product;- Fiscal Document Platform: internal product providing a set of integrations to store, download and query Fiscal Documents with high performance and availability;- Projects: engineer team focused in expand the value of the SaaS platform providing customizations for our client needs;- Product & Technology Operations: works on improvement of the efficiency and quality of the product development processPart of my efforts was spent creating a Community team to increase the engagement with the brazilian engineering community with the following actions: participating in events, giving speeches, writing articles, producing videos and developing open source codeDuring this time, the Product & Technology Operations area was created – as a fusion of pre-existent teams (QA, TechOps) and the creation of new ones (Agile, ProdOps and InfoSec). Since its creation, we could reduce our lead time by 30%, increase the delivery efficiency, map and improve the product development process and generate data to enrich discussion. We also implemented OKRs in the whole organization.At this position, I was also responsible for bringing the Engineering point of view into strategic discussions with my peers and C-levels, providing insights to the business, capturing opportunities through technology and giving a direction to our department initiatives.

During the first months of 2021, the R&D areas were redesigned due to major changes in the company. One of my main duties was to ensure we could maintain the high level of engineering and keep low levels of turnover during these major changes.I had been working, together with the leadership team, in the career plan, leadership structure and employer well being. This actions lead to an increase of the e-NPS and a low turnover rate (bellow benchmarks)

I was responsible for an engineering team with more than 30 employees, divided in five multidisciplinary product squads. My main duties were:- ensure systems are available; - facilitate resolutions of high priority issues;- plan architectural changes with other technical leaders;- define and create initiatives to achieve company's strategy;- evaluate performance of tech leads, helping them to develop their careers;- implement process improvements to increase team efficiency;- maintain a positive work environment for the team.As a manager responsible for the engineers’ careers, we started the first Individual Development Plan, helping employees develop their professional skills quickly and advance in the company through a structured feedback plan.On the technical side, the team I lead migrated the majority of our services to a Continuous Delivery lifecycle (including a monolithic application with many of 12 factor app caveats), implementing automation and observability best practices to guarantee the quality of delivery.

Arquivei's main product was created to obtain, store and provide easy access to Fiscal Documents (DF-e or "Documento Fiscal eletrônico" in Portuguese) for our customers. In order to achieve this, the Arquivei's system must communicate with SEFAZ webservices (a Brazilian government agency) to obtain all XML files that represent the Fiscal Documents of all Arquivei's customers. As the number of XMLs grows, it becomes more complex to retrieve large amounts of data from SEFAZ SOAP Web Services.Working as a Tech Lead, I designed and deployed a major architectural change in the core services used to consult from SEFAZ. This change was built to increase scalability of Fiscal Documents (DFes) consulting from SEFAZ , allowing to substantially increase the volume of XMLs obtained without any perceived delay.

As a Lead Software Engineer, I was responsible for the engineer team ( 5+ engineers) of the startup – this including the roles of System and Software Architect, Agile Master, Engineer Manager, Senior Backend Developer. My major contributions were:- Defining a strategy to break a non-scalable monolith application into a scalable, robust and fault tolerant microservices application minimizing the impact to the final user during this transition.- Developing and implementing a software architecture to our backend systems based on Clean Architecture (Robert Martin)- Management of product lifecycle and ceremonies (planning, refinement, dailies, retrospectives and others), as an Agile Master. - Career management of the engineers, following their performance, giving feedback, and creating a space to advance in their career.- Software development in PHP, Node.js and MongoDB- DevOps Culture adoption, using automated processes (CI/CD, IaaC, containers, observability) in order to guarantee a fast feedback deployment cycle while minimizing the friction to deliver value to the final user.As the CTO of the company, I also had the responsibility of deploying and following business and product KPIs, collaborating on the strategies of the company with other managers, investors or board members.

I joined the team in an early stage, being the second employee of the company. During this time, I had the pleasure to contribute to the first deployment of two major projects.Claro Campaign ManagerI worked as Technical Leader and Project Manager in a project to launch a platform that manages and supports real time marketing campaigns using a Complex Event Processing (CEP) tool. This was the highest revenue-generating project of Stefanini Inspiring.Febrafar Campaign EcosystemI lead a team in the development of mobile app templates and a platform to supply white label apps to pharmacy and drug store brand associates of Febrafar. With that platform and templates, any drug store associate to Febrafar could have a brand new mobile app deployed in a few days.I also was responsible for managing this account, directly engaging with clients, evaluating their needs and proposing delivery roadmaps.

I worked for two years on the product team of Spring Mobile Solutions on the development of its mobile framework. Programming in Objective-C, I was part of the team that built all the features for the framework for iOS. Besides Objective-C, other technologies were used in the product included:: - JavaScript: used to program the framework;- UltraLite: to provide a mobile database with capability to synchronize with a server database;- SQL Server: the server database;- C#: documentation, automated code generation and server side framework;- Java: to build tools interchangeable between different mobile teams (iOS and Android).The team that I was a part of had a strong basis in the agile process, resulting in a self-managed team with high performance and complementary skills. This environment encouraged the members to share their experiences, helping to increase the knowledge of the team. The team also used good practices for continuous delivery including automated builds in Jenkins, unit tests and functional automated tests to make sure that all development was available to the final user in a timely manner.Achievements:- Automated Test Presentation: I made a presentation, open to the product area, discussing best practices in automated tests and where to use each type of automated tests in the pipeline of the product build.

Working in the role as Product Architect on development of a new pre-paid topup management product, I was involved in the decisions of which technologies, design patterns, frameworks and tools best fit each development situation.At the same time, in the Technical Leadership area, I alternated between leading the development team in developing new features of products and leading the support team in fixes and improvements on the product to increase reliability. As part of the support team leadership, I led the testing for the official release of the product.I also worked as developer on critical issues of the product using Java, OSGi, Spring Dynamic Modules and Oracle Database.Achievements- Innovation Time: I gave a lecture in a series of innovative themed lectures, discussing the use of non-relational databases. This presentation was open to all employees of Portugal Telecom Brasil and it received high scores by the listeners.- Zero Production Bugs: In the first delivery of the product to a Telecom Carrier, we had no bugs found in the production environment.

As systems analyst, I participated in the design, development and customization of several processes in the BSS modules of the NGIN*. The BSS modules were developed using Oracle PL/SQL and Shell Scripts and were created to work on scenarios of high availability, fault tolerant and real time operations.Achievements- Vivo On: I was the Technical Leader of the first release of Vivo On which was considered one of the most successful Vivo projects of all time.-Communication Module Design: I designed an entire new module to make communications easier between the BSS Modules and the platforms outside of NGIN. This new module helped decrease the cost and the time spent to customize NGIN.*NGIN is the acronym for Next Generation Intelligent Network, a Portugal Telecom software product.

As a member of an agile team, I participated in the development of Bradesco Bank's personal credit website. In this project, we used a wide range of Java technologies, such as Java Server Faces, CSS, Spring Framework, Hibernate and Microsoft SQL Server.
