Mode of Work: Hybrid

Key Responsibilities:

• Analyze the existing monolithic system and define service boundaries.
  
• Decompose modules into scalable microservices.
  
• Design the target architecture for IoT ingestion, business services, and integration layers.
  
• Define APIs (REST/gRPC) and inter‑service communication patterns.
  
• Establish standards for retries, fault handling, idempotency, and resilience.
  
• Work with Cloud Architect to define MQTT-based IoT communication flows.
  
• Define message formats, event flows, and data contracts between devices and services.
  
• Define data ownership per service and transactional boundaries.
  
• Implement consistency strategies such as eventual consistency.
  
• Collaborate with DBA on schema strategies and cross‑service data flows.
  
• Review system designs, API specifications, and critical code implementations.
  
• Establish and enforce coding standards and architectural best practices.
  
• Identify and resolve performance bottlenecks in monolith and microservices.
  
• Architect solutions for high-throughput IoT data and low-latency APIs.
  
• Ensure horizontal scalability and reliability of the platform.
  
• Mentor developers on microservices and distributed systems concepts.
  
• Conduct architecture reviews, design sessions, and knowledge‑sharing workshops.
