Turning Vision Into Reality Through
Code & Innovation
I'm an AI Engineer and Full Stack Developer specializing in intelligent document processing, natural language interfaces, and cross-platform applications. Currently pursuing Informatics at Telkom University with a GPA of 3.60.
At Telkom Indonesia, I built OCR-powered document validation systems processing commissioning test reports with multi-layer LLM verification. At Infomedia, I developed multi-marketplace e-commerce platforms integrating TikTok Shop and Shopee APIs with real-time inventory synchronization.
I architect production systems that handle real business workflows. My work spans from RAG-based educational platforms to NL-to-SQL chatbots for financial analytics. I focus on building tools that solve actual operational challenges, not proof-of-concepts.
