Backend Engineering and Distributed Systems

Develop robust, horizontally scalable and fault-tolerant backend systems and event-driven architectures for business-critical applications.

Service Overview

Mission-critical applications in banking, healthcare, public administration and digital commerce demand backend systems that remain resilient under high concurrency. We engineer distributed backend architectures using Java (Spring Boot), C# (.NET), Apache Kafka and Amazon SQS.

Heartbeat’s Architectural Approach

We design domain-driven microservices and modular backend services paired with asynchronous event-driven messaging. Using Apache Kafka for high-throughput event streaming and Amazon SQS for reliable queue processing, we ensure fault isolation, eventual consistency and predictable horizontal scaling.

Business Problems Solved

  • 01.Monolithic backend bottlenecks that degrade performance during peak transactional load.
  • 02.Synchronous request chains where a single slow downstream service causes cascading failures.
  • 03.Data inconsistency and lost events across distributed business workflows.
  • 04.High technical debt that slows down feature delivery and increases regression risk.
