• Integrate and support real‑time API calls across policy and claims systems.
• Handle client‑specific configurations, including custom rules and data inputs.
• Leverage AI tools (e.g., Cursor) to navigate and analyze multiple repositories.
• Contribute to improving developer workflows, including AI‑assisted processes.
• Collaborate within an Agile/Scrum team (execution‑focused role).

Skills and Requirements

• 5+ years of experience in full stack development (mid‑level preferred) – 60% back end, 40% front end.
• Strong experience with .NET / C# – backend development focus.
• HTML/CSS knowledge.
• Experience working with or migrating legacy systems.
• Solid understanding of API development and integration.
• Working knowledge of modern JavaScript frameworks (Vue.js preferred).
• Experience using Git and working across multiple repositories.
