About Me

Lucas de Paula profile photo

Frontend Developer with Product Vision

Hello! I'm Lucas de Paula, a front-end developer passionate about transforming ideas into functional, accessible, and scalable digital experiences.

Throughout my career, I've worked on projects for fintech, energy, healthcare, and technology companies. I combine performance, usability, and design to deliver solutions that work effectively — both for end users and the teams maintaining the product.

Beyond coding, I have a strong interest in UX/UI and software architecture. I thrive in collaborative teams while being comfortable taking responsibility and making technical decisions when needed.

If you're looking for someone who understands both the interface and the underlying logic, let's connect.

My Journey

The evolution through the years

2022

SmartNX

I worked on the development of the NxSuite SaaS platform, specialized in omnichannel customer service powered by chatbots. I was responsible for building a dynamic interface using React JS and WebSocket to enable real-time support, ensuring a smooth experience for both operators and clients. I led integrations with external APIs such as VTEX and developed scalable data dashboards with a strong focus on performance. I refactored critical parts of the codebase using Atomic Design, functional programming principles, and best practices like DRY and KISS. I also identified and resolved security vulnerabilities, improving the platform's reliability and stability.

SPDATA

I served as a front-end developer and team lead on two healthcare-focused systems built with Vue.js, integrating with government APIs. I developed robust interfaces for internal use in high-reliability environments, prioritizing scalability and clear data visualization. I contributed to architectural decisions, provided technical mentorship to the team, and standardized reusable UI components. The project required strict compliance with technical regulations and a user-centered design approach for critical environments.

Axis Mobfintech

I contributed to several internal projects at Mobfintech, focusing on building real-time interactive dashboards using React and TypeScript. I developed integrations with payment APIs, including Pix transaction support and QR code generation. I helped structure internal component libraries, enforced code standardization, and implemented high-performance, accessible components. The delivered solutions significantly improved data analysis workflows and decision-making for end users.

Versatus

I led the front-end development of the Kosen Energy project, a solution for energy pricing and meteorological data analysis. I designed a decoupled component architecture to support dynamic report generation, advanced filtering, and interactive charts. Beyond the technical implementation with a performance-driven mindset, I actively participated in UX decision-making, improving user flows and overall usability. The enhancements significantly boosted the platform's navigation experience and operational efficiency.
