What I'm looking for

I'm looking to lead scalable, secure AI-powered full-stack and backend systems, contribute to cloud-native architecture, mentor engineers, and build practical GenAI, RAG, and agentic workflow solutions.

At Midwestern, I lead architecture and development of Python, FastAPI, Django, and Node.js microservices, improving API performance by 40% through async processing, Kafka, RabbitMQ, Celery, and Redis.

I direct GenAI and agentic backend initiatives using LLMs, RAG, LangChain, embeddings, vector databases, and prompt engineering, improving AI response accuracy by 45%. I also own backend architecture and database optimization across PostgreSQL, MySQL, MongoDB, Redis, SQLAlchemy, and vector databases.

Previously at PinTechSolution, I designed 15+ microservices and built GenAI solutions, document-processing pipelines, semantic search, and workflow automation. I delivered full-stack AI applications with React.js, Next.js, TypeScript, AWS, Azure, GCP, Docker, and Kubernetes.

Across healthcare SaaS and AI-powered platforms, I bring eight years of experience building secure, scalable cloud-native solutions and mentoring engineers through design sessions, architecture reviews, and code reviews.
