What I'm looking for

I seek senior engineering roles building scalable, cloud-native systems where I can lead architecture, apply ML/LLM solutions, and mentor teams while improving reliability and delivery velocity.

I am a senior full-stack engineer with 10+ years designing and scaling backend systems, APIs, and SaaS platforms across e-commerce, healthcare, and analytics domains. I specialize in Python, Java, Go, and cloud-native architectures to deliver reliable, secure services.

I build event-driven microservices, real-time pipelines, and high-throughput messaging systems using Kafka, RabbitMQ, gRPC, Celery, and Redis, optimizing databases like PostgreSQL and Snowflake for performance gains.

I have implemented LLM and ML solutions with TensorFlow, PyTorch, OpenAI API, and LangChain to automate workflows and improve product ROI, and I lead CI/CD, containerization, and monitoring efforts across AWS, GCP, and Azure.

I mentor engineers, run Agile ceremonies, and collaborate cross-functionally to shorten release cycles, reduce bugs, and deliver production-grade features at scale.
