What I'm looking for

I seek roles where I can design scalable backend systems, apply GenAI to solve product problems, work in collaborative teams, and drive measurable performance and cost improvements.

I am a results-driven Senior Software Engineer with over 7 years of experience building high-performance systems using JavaScript, NodeJS, TypeScript, and Python. I focus on designing scalable backend architectures, serverless solutions, and cost-efficient data processing pipelines that directly reduce compute costs and improve operational reliability.

Throughout my career I have delivered production systems that process millions of records and notifications, including OpenSearch transform jobs handling 18M+ documents monthly and a WhatsApp bulk notification system capable of 1M+ notifications per session. I have also led GenAI initiatives—building LLM-powered resume parsers and hackathon-winning GenAI assistants—using HuggingFace and SageMaker for model deployment.

I collaborate closely with cross-functional teams, document systems clearly, and drive process optimization. My notable achievements include measurable improvements in cost, performance, and engagement across enterprise and startup environments, and I continually explore practical applications of LLMs and scalable cloud infrastructure.
