Januarizqi Dwi Milleniantoro — Application Support

About Me

Bridging Technology
& People.

I'm Januarizqi Dwi Milleniantoro, an Application Support Specialist based in Jakarta with hands-on experience at Faspay, PT Infosys Solusi Terpadu, and Telkom Indonesia — covering both B2B and B2C enterprise environments.

My work spans L2 incident handling, SLA compliance, deep log tracing with Kibana, and database querying across PostgreSQL, SQL Server, MongoDB, Redis, and Elasticsearch. I take pride in finding the root cause, not just the quick fix.

I also have a background in UI/UX Design, Manual Tester, iOS Development, and Web Development, giving me a broad perspective that helps me collaborate effectively with developers, QA, and business stakeholders alike.
