Solution Architect and team leader specializing in cloud-native AI solutions.
What I'm looking for
I am a Solution Architect and Team Leader with 8+ years delivering cloud-native solutions, AI-driven products, and full-stack applications for global clients. I specialize in AWS infrastructure, Generative AI (chatbots, RAG, ML pipelines), scalable architectures, and leading cross-functional teams to align technology with business value.
My hands-on background spans backend and data engineering (Python, Django, FastAPI), DevOps and cloud (AWS, Docker, Terraform), and frontend development (React, TypeScript). I have led projects that improved system performance, reduced analytics latency, implemented document-processing and search solutions, and mentored engineers through hiring and onboarding.
