• Backend Development: Work closely with the team to design, build, and maintain reliable backend services using Python, Django, and related technologies. • API Development: Create and evolve RESTful APIs to power our front-end and mobile applications and support integrations with third-party partners. • Performance & Optimization: Monitor, identify, and resolve bottlenecks to ensure fast, efficient, and scalable applications that deliver a smooth user experience. • Architecture & Design: Contribute to the technical architecture of our platform, ensuring scalability, maintainability, and robustness as the product evolves. • Security & Compliance: Implement and enforce best practices to guarantee the security and integrity of sensitive health data, in line with healthcare regulations.

• Design and evolve Node.js / NestJS services powering systems that operate at scale • Take architectural decisions that balance scale, cost, and long-term maintainability • Build well-typed, thoughtful REST contracts for high volume flows • Think in versioning, backward compatibility, and clean boundaries • Model and optimize MongoDB / Firestore schemas for high read/write workloads • Design atomic updates and consistency strategies for distributed systems • Implement queues, caching layers, and rate limiting to handle burst traffic gracefully • Design for failure modes before they happen • Ship modular Vue 3 UIs that efficiently consume APIs • Optimize realtime updates and state management (Pinia) • Improve Core Web Vitals and perceived performance • Instrument logs, metrics, traces, and alerts • Participate in on-call • Debug real production issues • Drive post-mortems to meaningful closure (not just documents) • Review code thoughtfully • Support junior engineers • Raise engineering standards across the team

• Own the full lifecycle of Opportunities backend: translate business and customer needs into scalable, production-grade services • Design and evolve the data model for pipelines, stages, deals, and associated entities — getting consistency, throughput, and query patterns right • Build and scale APIs, event-driven workflows, and background jobs that handle high-volume writes, automations, and integrations • Tackle distributed systems concerns: idempotency, eventual consistency, race conditions, hot tenants, and noisy-neighbor isolation • Improve performance and reliability of large pipelines (millions of opportunities per workspace) through indexing, sharding, caching, and query optimization • Ship end-to-end when needed — including UI changes in Vue — without blocking on cross-functional handoffs • Instrument the system: logs, metrics, traces, and SLOs that make production behavior legible • Drive incident response, postmortems, and the engineering hygiene that keeps a high-traffic product healthy

• Projetar, desenvolver, testar, implementar e manter soluções de software de alta qualidade • Traduzir requisitos de negócios e funcionais em especificações técnicas claras • Colaborar na arquitetura de sistemas, implementação e testes • Solucionar problemas e resolver questões técnicas relatadas por equipes internas ou clientes • Contribuir para o desenvolvimento de aplicações voltadas para o usuário e serviços de backend • Promover e manter padrões de desenvolvimento e melhores práticas de engenharia de software • Participar ativamente de revisões de código, programação em par e cerimônias ágeis • Fornecer insights no planejamento de projetos e na tomada de decisões técnicas.
