What I'm looking for

I am seeking a role that fosters innovation and collaboration, allowing me to leverage my skills in backend development and AI to create impactful solutions.

With over 7 years of experience as a Senior Backend & AI Engineer, I specialize in scalable system design, API development, and performance optimization. My proficiency in technologies such as Node.js, Django, and cloud-native solutions like AWS and Docker has enabled me to successfully deliver high-quality systems that handle millions of requests daily. I have a proven track record in fintech integrations and compliance-driven solutions, showcasing my ability to adapt and excel in fast-paced environments.

At Novomind, I developed an AI-powered Chatbot, integrating machine learning algorithms and natural language processing to enhance customer interactions. My role involved configuring infrastructure for fast inference and optimizing database performance using PostgreSQL and MongoDB. Previously, at Sumitomo Mitsui Banking Corporation, I improved website response speed by 30% and implemented a microservice-based infrastructure, demonstrating my commitment to delivering efficient and scalable software solutions.
