What I'm looking for

I am looking for a role that challenges my skills in AI and backend development, fosters collaboration, and offers opportunities for continuous learning and growth.

I am a Senior Backend & AI Engineer with over 7 years of experience specializing in scalable system design, API development, and performance optimization. My expertise spans across various technologies including Node.js, Django, and Golang, with a strong focus on cloud-native solutions such as AWS and Docker. I have a proven track record of implementing microservices architecture and optimizing databases to handle millions of daily requests efficiently.

In my current role at Novomind, I successfully developed an AI-powered Chatbot that integrates machine learning algorithms and natural language processing. I have also worked on fintech integrations, enhancing payment gateways, and ensuring compliance-driven solutions. My experience includes designing robust CI/CD pipelines and collaborating cross-functionally to deliver high-quality systems that meet tight deadlines.
