What I'm looking for

I’m looking for a senior role where I can own cloud-native full-stack development and production AI features, collaborate cross-functionally, and optimize high-performance platforms that drive measurable business impact.

I’m a Senior Software Engineer with 6+ years of experience designing and delivering scalable full stack and AI powered applications across enterprise and SaaS environments. I build cloud native systems, integrate machine learning models into production, and optimize high performance web platforms to improve user experience and business outcomes.

At Sii, I led the development of scalable full stack applications using React and Node.js, supporting over 50,000 active enterprise users daily. I architected microservices-based backend systems with Node.js and Docker, integrated OpenAI-powered intelligent document processing, and improved frontend performance by reducing page load times by 1.8 seconds while also delivering RESTful and GraphQL APIs at scale.
