Mary Sopna

I’m a Senior Backend Engineer with 7.5 years of experience building and maintaining high-scale Python services, owning features end-to-end from design through production support. I specialize in FastAPI and Django, with a strong focus on performance, reliability, and clean engineering practices.

At TEKsystems, I independently designed and maintained critical backend services for the Blue4u platform, translating complex healthcare requirements into incrementally deliverable, production-quality code. I architected data ingestion pipelines for unstructured medical documentation and chat transcripts, using Python-based background jobs and Kafka for real-time, at-scale processing.

I also contributed to the platform’s GenAI roadmap by implementing retrieval-augmented generation (RAG) and reasoning workflows to automate extraction of key insights from medical policies. I integrate unstructured data pipelines with LLM workflows and vector search capabilities to support enterprise use cases.

I’m highly experienced in identifying performance bottlenecks and reducing API latency (4s to 1s) while ensuring 99.9% uptime. I establish standardized logging, error handling, and observability patterns, participate in on-call rotations, and lead code reviews to strengthen shared ownership, security, and maintainability.
