Responsibilities

• Independently own the full stack, from front-end and service layers to backend, data, and reporting.

• Build and support enterprise-grade web applications using modern stacks: React, .NET Core, Python, APIs, SQL Server / PostgreSQL, and SSRS.

• Develop Python services, data-processing routines, and automation across the application and pipeline layers.

• Use DuckDB for fast, in-process analytical queries over structured and columnar data, powering reporting, validation, and data-quality checks.

• Design and maintain structured and unstructured data pipelines (ETL/ELT and document / OCR / NLP ingestion) feeding production workflows.

• Drive deployment automation, environment readiness, and performance optimization for seamless, zero-disruption releases.

• Own and optimize the CI/CD pipeline across hybrid (Azure, AWS, on-premise) ecosystems, keeping assets secure, testable, and auditable.

• Tune and optimize queries for performance, reliability, and reporting accuracy in high-volume environments.

• Translate business needs into secure, scalable technical architectures, embedding data protection and compliance by design.

• Resolve high-priority production incidents with precision, ensure zero-downtime operations, and proactively prevent recurrence.

You're not just shipping code. You're building high-impact platforms that touch lives, ensure compliance, and power payer operations.

• Deliver healthcare solutions that work at scale, with reliability, speed, and security built in.

• Own production performance metrics and implement observability across app layers, APIs, and data-ingestion points.

• Collaborate deeply with product managers, QA, and business analysts to ship features that are user-friendly and technically sound.

• Own multiple product modules and pipelines simultaneously, balancing delivery with quality and continuous improvement.

• Apply strong design patterns, architecture principles, and agile delivery to accelerate time-to-market.

• Proactively remove roadblocks, anticipate risks, and communicate mitigation plans clearly to stakeholders.

• Internal: Partner with data engineers, DevOps, business analysts, client-service teams, and tech leads. Share knowledge, mentor teammates, and grow technical depth across the team.

• External: Engage with client-side stakeholders and, on occasion, executive teams to understand expectations, demo capabilities, and bridge business needs with technical delivery.
