What I'm looking for

I seek a senior engineering role building GenAI/AI products with a collaborative, growth-focused culture, clear ownership, and opportunities to scale systems and mentor teams.

I am an experienced Engineering Manager who leads high-performance development teams to build robust, scalable GenAI and AI/ML solutions using Java and Python. I focus on delivering measurable product improvements—such as an 87%+ RAG bot accuracy and major efficiency gains in call-transcription systems.

I have led multi-disciplinary teams across startups and product companies, implemented agile practices that reduced time-to-market by 60%, and scaled systems for high-throughput use cases (for example, processing 100,000 call volumes in one second with Kafka and Elasticsearch).

My work spans cloud deployments (AWS, Azure, GCP), multi-tenant architectures, and end-to-end ML productization. I mentor engineers, build training programs, and drive cross-functional collaboration to align technical delivery with business goals.
