01. About Me

Backend engineer building reliable production systems.

I'm a Python backend engineer with 4+ years of experience building and maintaining production backend systems with FastAPI, Django, and Flask. I design REST APIs, microservices, and third-party integrations backed by PostgreSQL, MySQL, and MongoDB, with asynchronous processing through Celery, RabbitMQ, and Redis.

At SaveLife.AI I work on the Python/FastAPI microservices platform behind medical AI products, with a focus on EHR/EMR integrations (HL7 v2, FHIR R4) and DICOM/PACS imaging pipelines. I have contributed to four FDA-cleared AI products. Before that, at HNH Tech Solutions, I built Django and Flask REST APIs, third-party integrations, and Selenium automation.
