Since the merger of UserZoom and UserTesting I’ve worked as a software developer in a fully distributed team focused on building a new test management experience that brings together the best capabilities of both systems in a simpler but powerful package. I’ve used my frontend expertise to help introduce surveys to the new platform, quickly adapting to new technologies, ways of working and requirements to build the right thing the right way, all under time constraints, differing time zones and cultures.

Among my areas of impact are adopting component testing with Cypress in the new features being developed to allow us to move forward faster and confidently, and using newly gained RxJS knowledge to solve bugs present in the legacy system and provide a speedier feedback in the survey builder. Merely a week after their release, 2 out of every 10 completed research sessions were surveys and we had achieved 15% of our customer usage goals for the entire year, which wouldn’t have been possible without a robust and performant survey-building experience.

Angular, NgRx, RxJS, Jest, Cypress, Sass, React, Redux, NodeJS, Apollo GraphQL, Ruby on Rails, GitHub, GitHub Actions, CircleCI, ArgoCD, internal tools.

Frontend developer in a cross-functional Scrum squad responsible for developing and maintaining the part of the platform which enables UX researchers to create, configure and manage studies. We’re mainly concerned with analysis, splitting and delivery of new product features, but doing this also involves managing tech debt and balancing business priorities with sustainable development practices that enable us to keep evolving the system in the long term.

Some features I’ve had the opportunity to work on include the implementation of a re-designed study creation flow which simplifies choosing the right research approach, new study capabilities for mobile app testing, and part of an ongoing large-scale integration effort to offer powerful and diverse user research methods through a unified platform that can scale along with every research teams’ needs.

Technology stack:

React (Jest), Redux, styled components, Sass, CSS, GitHub, GitHub Actions, XSLT, jQuery, internal tools.

Developer in a team for a Germany-based client, in which I supported the maintenance and evolution of a product in charge of providing personalised product recommendations to users. As one of the world’s biggest e-commerce companies, the main concern was developing strategies to seamlessly scale the system.

Ensuring data redundancy, the least amount of downtime and the most performant recommendation experience was paramount. Technically this involved (but wasn’t limited to) a change in product data persistence mechanisms and a refactor of the codebase to reduce complexity by moving towards a Clean Architecture approach, all while developing new product features.

Technology stack:

Java (Spring Boot, Thymeleaf, JUnit, Mockito), AWS, Docker, Terraform, bash, GoCD, GitHub, Kibana, Grafana, MongoDB Atlas, Redis, plain JavaScript micro frontend (Jest, Cypress), Togglz.

Junior developer in a team for a leading German real estate company, maintaining a system that connects property sellers to real estate agents. The system interacts with the client’s existing client relationship management solution sending email notifications and billing invoices, and integrates a dashboard allowing agents to manage the number of potential customers they receive.

As part of the team, I worked on implementing features and user flows to increase the quality of customers acquired through the system, contributed in the migration process to the new brand identity for the company, and supported the onboarding of three new client developers during the product’s handover phase.

Technology stack:

JavaScript micro frontend (React, Redux, Testing Library, Selenium), CSS (Sass), Node.js lambdas running on AWS, Java (Spring Boot, JUnit, Mockito), Jenkins, Kibana, Datadog, PostgreSQL.

I was part of the communications team for a feminist organization group that carries out two of the biggest women’s rights marches in Paraguay. Within the team, my work included planning and preparing visual deliverables to publicize events, complement educational measures and engage public opinion on women’s issues.

Despite strong backlash and misinformation from anti-rights groups and conservative mainstream media, more than three thousand women took to the streets during the International Day for the Elimination of Violence against Women in November 2017, and more than five thousand participated in the International Women’s Strike of 2018.
