Duties

Backend & OCR Systems

• Design, implement, and maintain workflows for Optical Character Recognition (OCR) and image processing, covering everything from data ingestion to evaluation and output.
• Develop scalable backend services in Python using FastAPI.
• Integrate with third-party OCR engines through REST APIs, managing retries, errors, and fallback strategies.
• Implement preprocessing techniques and quality improvement measures.
• Contribute to improving OCR accuracy by utilizing feedback from manual reviews and downstream validation processes.
• Design data models and storage solutions for OCR results, metadata, and audit trails using PostgreSQL.

Distributed & Cloud Architecture

• Build message-driven services using Azure Service Bus for asynchronous processing.
• Deploy and operate services on Azure, including AKS.
• Containerize applications using Podman and support CI/CD pipelines.
• Contribute to system scalability, fault tolerance, and observability.

Full-Stack Skills
