I am drawn to the opportunity to build dependable reporting and AI capabilities for wealth management and financial services. In my current role at Northwind Wealth Technology, I lead architecture and delivery for advisor reporting and financial-data services , working across product, compliance, and quality teams. That work closely matches Crescent Harbor’s focus on secure reporting platforms shaped by both business needs and regulatory requirements. My experience combines hands-on .NET and Python development with technical leadership across APIs, AWS, and data-intensive services. At Blue Mesa Capital Systems, I introduced Kafka-based processing for selected reporting feeds, using idempotent consumers and retry handling to reduce duplicate records during replay and recovery. I have also delivered portfolio and performance reporting services with .NET, Python, REST APIs , SQL Server , and PostgreSQL, and have guided architecture discussions and code reviews across distributed systems. I bring direct production experience with AI and LLM applications , including the evaluation, governance, and operational care this work requires. Since 2024, I have advanced production AI and LLM features for report research workflows, adding evaluation routines, controlled data access, governance checks, and cost monitoring before broader release. I have designed stateful agent workflows with explicit memory boundaries and recovery paths, and use Claude Code and GitHub Copilot in implementation, code review, and test drafting with engineer oversight. Crescent Harbor’s combination of financial reporting, production AI, and cross-functional engineering is a strong fit for the work I have led throughout my career. I would value the opportunity to contribute my experience in resilient services, AWS operations, CI/CD , incident response , and mentoring to your team. Thank you for considering my application. I look forward to discussing how my background can support Crescent Harbor’s reporting and AI platform work. Sincerely, Click to edit Draw your signature below Clear Generate Signature Save X Levi Le
