Full Stack Software Engineer (backend-oriented) specializing in scalable, secure systems.
What I'm looking for
I am a Full Stack Software Engineer with 10+ years building high-performance, scalable systems for finance and healthcare, focusing on backend architecture and cloud-native applications.
I design and implement microservices, event-driven pipelines, and low-latency APIs using Python (FastAPI, Django, Flask), Golang, and Node.js, and I have led migrations to serverless and containerized environments on AWS and Google Cloud.
My work emphasizes security and compliance (HIPAA, PCI-DSS), real-time data processing, ML-enabled anomaly detection, and end-to-end system performance that scales to millions of users.
