What I'm looking for

I’m looking for a team where I can design secure, scalable Python/FastAPI microservices on AWS, build event-driven systems, and ship AI-enabled backend features—prioritizing reliability, performance, and engineering best practices.

I build backend systems that turn complex business needs into reliable, scalable platforms. Over the past 7+ years, I’ve engineered Python-based services, distributed architectures, and cloud solutions across Healthcare, FinTech, SaaS, and Enterprise environments—improving performance, reliability, and engineering efficiency.

Most recently, I’ve architected Python-based FastAPI services on AWS with PostgreSQL to support 500K+ monthly users while maintaining 99.9% availability. I design microservices and API-driven architectures, use event-driven processing with Kafka, RabbitMQ, and Celery to increase throughput, and deliver AI-integrated backend capabilities with OpenAI APIs and LangChain RAG workflows.
