o Back-office reporting and reconciliation tools for statements, balances, and DCO communication.
Write high-quality, production-grade code using .NET Core and C++, with an emphasis on performance, correctness, and maintainability.
Define and build scalable APIs, ensuring seamless integration with frontend systems (SwiftUI, Jetpack Compose, Next.js).
Own technical decisions across services, including data modeling, service boundaries, observability, and error handling.
Deploy, monitor, and support backend systems in a cloud-native AWS environment (DynamoDB, Kafka, EC2, EKS).
Collaborate closely with product managers, architects, compliance teams, and fellow engineers to iterate on requirements and deliver production-ready solutions.
Guide and mentor junior engineers through code reviews and technical support, while staying hands-on with daily development tasks.
