What I'm looking for

I seek roles where I can lead end-to-end AI and full-stack projects, architect cloud-native solutions, mentor engineers, and deliver measurable business impact in collaborative, growth-oriented teams.

I am a Senior AI & Fullstack Engineer with 8+ years building scalable, secure, and intelligent systems using Python, .NET, and modern frontend frameworks. I design and deploy end-to-end solutions—covering frontend UI/UX, backend services, AI model deployment, and cloud-native microservices—while mentoring teams and driving DevOps adoption.

My work includes architecting AI-driven forecasting platforms that improved forecasting accuracy by 35%, implementing cloud solutions on Azure to reduce operational costs by 25%, and delivering responsive enterprise dashboards and recommendation engines that boosted retention and performance. I prioritize robust system design, measurable business impact, and collaborative delivery.
