As a contractor for Invesco, one of the largest asset management firms in the US, I lead efforts on the UI team to modernize “Vision,” an internal tool whose legacy codebase has reached its performance limits. My role involves designing the frontend architecture, developing POCs with Micro-Frontend and BFF approaches, and mentoring engineers to ensure best practices. The primary focus of this rewrite is to enhance both performance and maintainability by implementing modern, cutting-edge techniques.

We use a monorepo managed by NX with React 18, Next.js, TypeScript, Redux Toolkit, and RTK Query as core technologies, alongside a Storybook-documented Design System. With ~90% test coverage from Vitest and React Testing Library, supported by ESLint and SonarQube, we maintain high code quality. Automated CI/CD pipelines and Gitflow enable seamless deployments. To ensure optimal performance, we manage server state using a combination of RTK Query and a Backend for Frontend (BFF) architecture, which seamlessly integrates with multiple backend services.

At Conversica, I contributed to the Partner Portal as a key UI team member, setting architectural standards and developing reusable components in React, Redux Toolkit, and RTK Query. My work included leading a major rebranding effort in under two weeks, which involved replacing +1,500 hardcoded tokens to support Dark Mode and White Labeling.

I created a POC for migrating the legacy PHP system to React using Micro-Frontends with single-spa, supporting a seamless transition to modern technologies. My role also involved close collaboration with backend, Product, and Design teams, as well as mentoring engineers and presenting solutions in company architecture meetups.

At SIDIA, a R&D institute for Samsung, I played a key role in a team that developed a sophisticated system to detect duplicated bug reports and recommend the right tech groups to address them. As a full-stack developer, I worked on frontend applications with Angular, supported backend development using Node.js and Python, and closely collaborated with the Design Team to create new features.

I spearheaded DevOps efforts by automating CI/CD processes to ensure seamless deployment of 8+ microservices across development, QA, and production environments. I designed and implemented CI/CD pipelines using Concourse CI and Docker, and configured Traefik to manage communication between microservices. Additionally, I supported a team of 5 engineers throughout these initiatives.

I was invited back to join the UI Development team at VTinova to work on the same remote metering product I had previously supported from the hardware side. In this role, I focused on building web and mobile applications using React and React Native, leading efforts to create interfaces that allowed users to visualize vast amounts of data in real-time via WebSocket connections. The resulting interactive charts, tables, and maps significantly enhanced data visualization and usability, aligning the UI with VTINOVA’s commitment to innovation in remote metering solutions.
