Senior systems engineer specializing in AI evaluation, distributed backend architectures, and production-grade full-stack platforms.
What I'm looking for
I’m a Senior Systems Engineer and AI Specialist with deep expertise in distributed backend architectures and full-stack web applications. I build high-throughput, latency-sensitive Python and JavaScript/TypeScript infrastructures, then connect them to robust AI evaluation workflows and production-grade pipelines.
In recent roles, I’ve architected distributed backend services for automated AI evaluation pipelines, developing asynchronous, low-latency REST APIs with FastAPI and scaling write-heavy operations with Redis-backed queues. I’ve also designed structured model evaluation frameworks to improve LLM output accuracy, prompt durability, and security alignments.
I’m equally hands-on in dataset and geospatial work—engineering GIS mapping pipelines with QGIS, reconstructing 3D medical datasets from DICOM, and creating scientific visualization workflows in ParaView. Alongside that, I support cross-functional collaboration by leading remote technical teams, writing clear technical documentation, and translating complex requirements into scalable systems.
