About Me

Backend software engineer. I build distributed services, APIs, and data pipelines, and increasingly the applied AI systems that run on top of them.

MS Computer Science, Rochester Institute of Technology. Three years shipping production backends before that: Excellus BlueCross BlueShield (C#, ASP.NET Core, Azure, cut CI/CD deploy time 35%) and Vodafone Intelligent Solutions (Java, Spring Boot microservices, auto-triaged ~5,000 ITSM tickets a month).

  • Backend first. Event-driven architecture on Kafka, CQRS, Postgres schema and migrations, REST API design, Docker and Kubernetes
  • Applied AI second, and grounded in the same discipline. RAG retrieval pipelines, agent orchestration, and LLM evaluation treated as engineering problems with tests, traces, and CI gates rather than prompt tinkering
  • Open to new grad and early-career SWE roles, backend or applied AI. F-1 OPT, seeking H-1B sponsorship
  • Writing about what I build, weekly, on LinkedIn

Experience

Software Engineer, Excellus BlueCross BlueShield C# / ASP.NET Core / Azure Functions / Cosmos DB / Angular. Reduced CI/CD deployment time 35% and broken builds ~30%
Software Engineer, Vodafone Intelligent Solutions Java / Spring Boot microservices. Automated ITSM triage for ~5,000 tickets per month, saving ~7 engineer-hours weekly
Research Assistant, RIT Proteomics mass-spectrometry pipelines. Debugged C++ search engines (Comet, X!Tandem) on SLURM HPC
