What I'm looking for

I'm looking to build end-to-end AI-driven products, from intuitive interfaces to scalable backend systems, while collaborating with strong cross-functional teams and continuing to grow in generative AI and software engineering.

At Summon Cipta Inovasi, I build Next.js interfaces, Python FastAPI services, LLM workflows, and RAG systems for intelligent business applications. I focus on scalable architecture and low-latency AI interactions.

Previously, I developed REST APIs and AI services at Falah Inovasi Teknologi, including file summarization and content generation. I also bring hands-on UI/UX, mobile, IoT, Linux, Docker, and cross-functional delivery experience.
