What I'm looking for

I seek senior engineering roles where I can build scalable, secure SaaS systems, integrate AI/LLM features, work in cross-functional agile teams, and drive reliable cloud-native deployments with opportunities for technical leadership.

I am a Senior Full Stack Developer with deep expertise in Python, Django, Django REST Framework, and React, delivering scalable APIs, real-time features, and secure multi-tenant SaaS solutions across finance, e-commerce, cybersecurity, cloud storage, and education.

I have driven AI integrations using LLMs and embeddings for semantic search and automated content features, built robust background processing with Celery and RabbitMQ, and deployed containerized services on AWS with CI/CD pipelines to achieve high performance and maintainability.
