- Contribute to the development and continuous improvement of public APIs, internal SDKs, and shared frameworks, ensuring standardization, reusability, and high engineering quality across teams
- Design and implement high-performance integrations with external platforms and third-party services, focusing on scalability, resilience, and clear contract boundaries

- Committed to building high-quality, maintainable architectures. Hands-on experience applying architectural approaches such as event-driven, domain-driven design, and solid understanding of foundational engineering principles ( OOP, SOLID, ACID, and related concepts)
- Solid understanding of distributed systems: CAP theorem trade-offs, eventual consistency, data replication, scalability patterns, and fault tolerance
