What I'm looking for

I’m looking for a role where I can lead secure, scalable full-stack systems and modernize architectures, while building applied generative AI (RAG/LLMs) that’s production-ready. I want a team culture that values TDD, clean architecture, and mentorship.

I’m a Senior Full Stack Developer with 9+ years designing, developing, and maintaining scalable enterprise web applications. I specialize in full-stack delivery, back-end technologies, and system design—always with an eye on security, performance, and maintainability.

At Cisive, I led full-stack development of a cloud-based screening platform using ASP.NET Core, Angular, and Azure, building configurable workflows for criminal searches, employment verification, and sanctions screening. I also architected event-driven microservices on Azure Service Bus and Azure Functions, helping deliver 78% of criminal searches closed within one hour, while integrating RESTful APIs with enterprise systems like Workday, iCIMS, and Greenhouse.

In my recent work, I’ve built compliance-ready capabilities (including FCRA-compliant adverse action workflows with dispute tracking and audit-ready documentation) and strengthened identity verification with biometric facial recognition and forensic document validation. I also optimized sanction screening against OIG-LEIE, GSA-SAM, FDA debarment lists, and state exclusions, while improving large-scale SQL Server query performance for faster indexed searches.

I enjoy raising the technical bar through mentoring and code reviews, enforcing TDD practices, clean architecture standards, and Agile ceremonies. I’m also actively exploring generative AI—building a chatbot using Retrieval-Augmented Generation (RAG), integrating LLM APIs and vector databases, and experimenting with MCP and intelligent agent architectures.
