What I'm looking for

I’m seeking backend/ML engineer roles where I can design scalable microservices and build production NLP/LLM systems—leveraging Python/Golang, data engineering, and cloud platforms (GCP/AWS/Azure) to ship impactful models.

I’m a skilled AI software engineer with 5 years of experience in backend engineering, system design, and scalable API development through microservices in Python and Golang. I build NLP, recommendation systems, and LLM-based applications on cloud platforms (GCP, AWS, Azure), including TensorFlow Lite and Vertex AI.

At OmniReach, I’ve developed LLM-powered SEO enhancement recommendations and deployed an on-mobile TensorFlow Lite model for speech filtering and noise removal—replacing paid tools and saving $30,000/year. I also create fine-tuned models using BigQuery ML and Vertex AI, and build real-time data ingestion/profiling with Hasura, Apache Unomi, and Rudderstack.
