>AI Engineer•Generative AI & Computer Vision
I build RAG chatbots, research agents, and LLM pipelines with Python, FastAPI, and LangGraph. I also work on instance segmentation and image classification.
Applied AI across generative AI, multi-agent systems, and computer vision.
I am an Informatics Engineering graduate focused on applied AI. My work includes generative AI, multi-agent systems, computer vision, and the backend systems that support them.
During my AI Engineer internship, I worked on backend architecture, data ingestion, and evaluation. I collaborated with cross-functional teams to turn ideas into working systems.
I also have experience with instance segmentation and image classification. I currently work as an AI Engineer at PT Wiratek Solusi Asia, where I deploy local models on-premise and build RAG chatbots and AI agents for a partner company.
How I Work
From problem statement to monitored system.
My process covers the full AI lifecycle, from defining the problem and preparing the data to evaluation, deployment, and ongoing monitoring.
01Problem StatementDefine the user need, technical constraints, expected output, and success criteria.
02Data AcquisitionIdentify, collect, and verify the data required by the system.
03Data ProcessingClean, structure, annotate, or transform data for training, retrieval, or inference.
04System DevelopmentBuild the model, RAG pipeline, agent workflow, API, and supporting infrastructure.
05Evaluation & ValidationTest output quality, failure cases, latency, and reliability before release.
06Deployment & MonitoringDeploy the system, track production behavior, and improve it using observed results.
