Lecionas is a platform that allows teachers to elaborate high-quality assignments for their students simply and quickly.

With challenges like accurate search, easy assignment build, great UI/UX for teachers and WYSIWYG text editor to .doc file downloads, I had to:

• Integrate backend with ElasticSearch and develop in-house UI components to deliver better faceted and text search experience, resulting in ~1s filtering response time (~6x response time decrease)
• Different components solutions with A/B testing in order to improve conversion rate data-driven (like custom Paywall and Onboarding tour);
• Handle complex and well-defined data structure to ensure same quality from WYSIWYG text editor (with images and math formulas) to teacher assignment .doc file download;
• Ensure development best practices and code quality.

As full-stack software engineer and tech lead at SkillCert, a startup specializing in talent management and skill assessments, faced several pivotal responsibilities in this role. Joined a small yet highly experienced team and was at a point in time the only one responsible for the technical aspects of the project.

• First task was to lead and release SkillCert site.
• Subsequently, approximately one month after site's successful launch, transitioned our platform (backend and frontend) from B2C to B2B model, aligning our strategy with market demands;
• Coordinated closely with CPO and CEO to streamline site launch process and then to develop and execute comprehensive plan for transitioning to a B2B solution;
• Despite facing technical challenges, such as adapting to a new backend development stack involving Kotlin, Micronaut, and Hibernate, embraced the opportunity to upskill and overcome these obstacles;
• Within one year of these efforts, SkillCert achieved remarkable results. We secured solid customer base and exceeded 5,000 test takers on our platform

These contributions played a pivotal role in SkillCert's early success and established a strong foundation for future growth.

Data n' Quant Labs is Fintech company for quantitative trading. As a software engineer I was responsible for building the user logged site.

I was reporting directly to the Founders and collaborated closely with the designers and the backend SWE to seamless integrate with the API services;

To achieve the goal the stack chosen was a React and production-ready template to speed up the development.

Some feature highlights:

• Realtime notification component through WebSockets;
• User registration and authentication flow;
• Homepage based on each user profile using RBAC and admin area for CRUD operations;
• Insightful trading data visualization chart-based (Apex charts) pages; - Mobile first approach for full responsiveness;

Despite the platform has not been made available yet, the beta testers could provide feedback such as easy and seamlessly site navigation and also insightful data visualization through well-designed charts for each kind of data.

• Globoesporte.com is Brazil's most significant and leading sports site, with ~7 million unique daily user.
• As software developer, was responsible along with my team for developing new pixel-perfect site components, backend apps to serve as API, besides participating in product definition and design ensuring there was complete alignment between Tech, Designers and Business units.
• In micro-frontend environment, pixel-perfect, small bundle size, component complexity and great UX were main concerns in choosing each component stack (eg: React with Styled-Components or raw HTML, CSS and vanilla Javascript component stack).

• Was part of great mission to elevate service and infrastructure monitoring to another level at Globo.com.
• Acting mainly as developer at Infrastructure area - Monitoring Team at Globo.com specifically - I was responsible to develop an API layer that was able to integrate any company system software to our monitoring platform, taking as a premise Zabbix abstraction (our current base platform at that time).
• This allowed all monitoring CRUD operations to be automated and integrated to other platforms - like DBaaS, IaaS and others "aaS" - so that client, whether a person or a system, could manage its monitoring for themselves without knowing the least of Zabbix. And it also lead the company to move from lazy "ticket" model to self-service model.
