Leading AI & Data Programs
from Strategy
to Production

Shipped NOVA to production — an LLM-powered analytics chatbot enabling a 30-person CVM operations team to query live onboarding KPIs daily which is built on multi-agent event-driven architecture, SQL-based query generation, neural network chart rendering, guardrail frameworks (NeMo, Microsoft Guardrails, context-bound), and LLMOps. Cleared Infosec review and launched on schedule across global telecom markets.

Identified two compounding security risks in the NPS Survey Chatbot and Insights Agent before go-live — an unauthenticated access mechanism and unmasked PII in the LLM retrieval layer. Coordinated risk assessment across Infosec, Cybersecurity, and AI CoE, and drove a deliberate no-launch decision to protect customer data. Built a repeatable AI governance framework subsequently used to bring 3 POCs to funded production programs.

Secured funding and production approval for 3 POC initiatives — Recommendation Model (Ufone), Churn Prediction Model (KDDI), and RCA using Knowledge Graph — by building structured business cases for the AI Council/CoE. Coordinated cross-functional execution across engineering, data, and business teams.

Coordinated GA4 analytics validation for the By.U mobile app (Google Play Store) — tracking duplicate and missing event defects raised by the QA team, collaborating with the app development team on fixes, managing re-testing cycles, and signing off on launch readiness after resolution of launch-blocking defects.

Owned end-to-end delivery of 18 BI data extract pipelines supporting enterprise reporting for Telkomsel Indonesia (22M+ customer base). Maintained 100% SLA adherence across daily and monthly reporting cycles. Program-managed SQL optimisation efforts across data engineering teams, improving Snowflake compute efficiency and enabling scalable data processing for a 30% increase in users.

Governed high-priority incident management at Oracle Cerner — conducted root cause analysis for client-reported defects using Cerner's RCA tool, prepared and presented CAPA documents to senior leadership, and tracked corrective action closure. Achieved 100% on-time delivery across all client commitments and priority service changes across three cross-functional engineering teams.

Performed manual testing for Blood Bank (Laboratory Solutions) at Oracle Cerner — validating patient encounter registration, blood sample collection workflows, ABO blood group and RH phenotype typing (positive/negative), and antibody/antigen compatibility testing to confirm transfusion safety before patient discharge.

Led quality assurance and testing for IVR application migrations across Orange Slovakia (OSK), O2 UK, Deutsche Telekom (DTag), and Djezzy Algeria. Covered manual testing, end-to-end performance testing, integration testing, and production environment validation. Automated web application testing for Deutsche Telekom using Selenium with AngularJS and Protractor. Owned quality processes as Quality Champion for the OSK IVR migration (Nortel to HP OCMP platform).
