What I'm looking for

I’m open to business analyst, data, and applied AI roles and internships.

I am an Informatics graduate (cum laude) from Telkom University, focused on business analysis, data analytics and process automation. I enjoy turning loose business requests into clear requirements, reliable data and controlled workflows.

My experience includes a Market & Demand Analysis internship in Telkomsel's Fixed Broadband Business, where I audited an existing dashboard workflow, cleaned and validated field-survey data in Excel, and built a monitoring dashboard. I also served as a Teaching Assistant for three semesters at the Informatics Laboratory, teaching AI Fundamentals and Object-Oriented Programming, and led a five-person team that ran an AI-literacy program for 7th-grade students.

Alongside my studies I built eight prototypes with automated tests, including a data warehouse that reconciles 1,848 KPI cells with zero mismatches, a B2B deal desk with rule-based pricing and approval workflows, and a request-to-approval workflow supported by a full BRD, BPMN models and a traceability matrix. I am also the first author of a machine learning paper presented at ICICoS 2026 and published on IEEE Xplore.

I am looking for Business Analyst, Data Analyst or process-automation roles where I can combine requirements analysis, SQL, Python and Excel to help teams make decisions backed by evidence. Portfolio: dzahyk.github.io
