"Someone who can help you solve problems"

— the positioning I hope collaborators remember.

Cloud Engineer & AI Solution Developer

Building Scalable AI Solutions

M.S. in Computer Science and Information Engineering, with research in Information Security and Image Processing. In 2023, while volunteering at AWS Community Day, a session on building generative AI and cloud solutions powered by enterprise data set me on the path since — a gradual shift from software systems and web development toward data, AI, and cloud.

I work with a research mindset: clarify the problem and ground the foundation before building. When facing uncertainty, I prefer running a POC or validating feasibility through analogous tasks.

Focus Areas

Generative AI & Agentic Systems

RAG, Multi-Agent, LangChain. Experienced in choosing the right approach per context rather than applying tools by default.

From Data to Decisions

Tableau / Alteryx / SAP ETL. Led end-to-end BI pipelines from data sources to executive dashboards that actually drove decisions.

Cloud Solution Architecture

AWS / GCP / Docker / Kubernetes. AWS Community Builder (AI Engineering), actively learning and sharing within the community.

How I Work

Research-driven, direct, and pragmatic. I break down problems before acting and share opinions openly while staying open to others.
