What I'm looking for

I seek a role building scalable cloud-native data and AI systems with strong MLOps, automation, and cross-functional collaboration.

I am a Data Engineer and Machine Learning Engineer focused on building cloud-native data platforms and AI-driven systems that translate business requirements into production-ready solutions.

I have delivered end-to-end projects including LLM-based chatbots, ETL pipelines, and backend services using GCP and AWS, emphasizing performance, reliability, and cost efficiency.

My work spans observability, CI/CD, and MLOps practices — deploying services on Cloud Run, Lambda, and Vertex AI while integrating OpenSearch, BigQuery, and relational databases for analytics and retrieval.

I collaborate cross-functionally with Data Scientists, MLEs, and analysts, and I prioritize automation, documentation, and query/index optimization to reduce costs and improve system trust and uptime.
