Hi
I'm Marina!

Joined DocuPet, a fast-growing North American SaaS company, where I had the opportunity to work on modern cloud-native applications and collaborate with highly skilled engineers, architects, product managers, and company leadership.

Developed and maintained web applications, APIs, subscription services, event-driven workflows, marketing automation features, analytics solutions, and third-party integrations. Worked on projects involving GraphQL, Redis, DynamoDB, AWS, Docker, Symfony, and modern software architecture patterns, helping improve platform scalability, reliability, and maintainability.

Contributed to strategic initiatives such as customer communication platforms, subscription management, marketing automation, event processing pipelines, and AI-assisted development adoption. The experience significantly expanded my knowledge of distributed systems, SaaS architecture, cloud services, and modern engineering practices.

Worked on the development and maintenance of internal systems used by one of Brazil's largest state judicial institutions. Contributed to applications supporting court operations, administrative processes, and judicial workflows.

Participated in system analysis, software development, database maintenance, integrations, and ongoing platform improvements while working closely with business stakeholders and technical teams. Focused on delivering reliable and maintainable solutions in a highly regulated public-sector environment.

This role strengthened my experience in enterprise software development, institutional systems, and projects requiring stability, compliance, and long-term maintainability.

Joined one of Brazil's largest fintech companies, working on backend services responsible for payment processing, financial integrations, and transaction-related workflows used by millions of customers.

Designed, developed, and maintained microservices and REST APIs using Laravel, Lumen, HyperF, MongoDB, Docker, and PHPUnit. Contributed to scalable distributed systems handling financial operations where performance, reliability, and security were critical.

Worked within agile teams alongside engineers, product managers, and business stakeholders, helping deliver solutions that supported the continuous growth of one of Brazil's most recognized digital payment platforms.

Worked within the Brazilian Air Force Airspace Control Department (DECEA), one of the largest air navigation organizations in the world, developing systems that supported airspace management, operational security, drone monitoring, and air occurrence investigations.

Designed and developed fullstack applications, REST APIs, GraphQL services, and backend solutions using Laravel, React, MariaDB, PostgreSQL, Docker, and modern DevOps practices. Collaborated directly with military personnel, analysts, and operational specialists to transform complex business and operational requirements into software solutions.

In January 2020, I was promoted to Technical Lead, becoming responsible for technical direction, architecture discussions, code reviews, project planning, delivery coordination, and mentoring team members. I led projects related to air occurrences, drone operations, and operational security, helping ensure the successful delivery of mission-critical systems used in highly regulated and high-responsibility environments.

This role represented one of the most challenging and rewarding experiences of my career, combining software engineering, leadership, architecture, and direct participation in systems supporting critical national airspace operations.

Developed web-based solutions for Fiocruz, one of the most important public health and research institutions in Latin America. Worked on systems supporting internal processes, information management, and institutional operations.

Acted not only as a software engineer but also as a requirements analyst and Git Manager, helping organize development workflows, version control strategies, release processes, and quality assurance activities.

Collaborated with multidisciplinary teams throughout the entire software lifecycle, from requirements gathering and technical analysis to implementation, testing, deployment, and maintenance.
