Core Voice Network Engineer | Observability, Data Engineering & AI‑Driven Telecom Operations

With 25+ years of telecom experience, actively hands-on with Machine Learning & Data Science since 2021, I connect deep Core Voice domain expertise with modern enterprise observability, high-volume data engineering (~10M daily data points), Python microservices, and AI/MLOps operational intelligence. I design, build and support cross‑domain operational capabilities that enhance network visibility, reliability, efficiency and operational readiness through monitoring platforms, data‑driven insights and intelligent automation.

Transforming complex Core Voice network operations into data‑driven, ML‑enabled and automated environments that reduce risk, improve decision‑making and enable faster, more effective operational response.

Profile

About

I operate at the intersection of critical telecom operations, data engineering, observability and AI‑driven operational intelligence. With 25+ years of experience in Core Voice networks, I transform complex operational environments into reliable, measurable and automated platforms.

My work spans Core Voice/IMS operations, enterprise observability, high-scale data engineering (~10M daily data points), and modern MLOps practices. I support and evolve IMS/SDVoice environments for both mobile and fixed networks, contribute to Deutsche Telekom’s Common Operating Model for Europe (COME), and serve as a core member of the Agile NT MLOps & AI Squad on AI‑driven operational capabilities. I own and operate large‑scale monitoring platforms such as Grafana Enterprise, oversee Red Hat–based operational environments including vulnerabilities, patches and upgrades, and design Python‑driven ETL pipelines, microservices and automation workflows.

Across PostgreSQL/TimescaleDB, MySQL, MongoDB and InfluxDB, I design schemas, process operational data and build KPI‑driven insights that improve visibility and decision‑making. I also contribute to MLOps architectures, machine learning initiatives and AI adoption within telecom operations, while supporting Linux‑based environments through lifecycle management, upgrades, security remediation and operational readiness activities.

Beyond engineering delivery, I strengthen team capability through ML/AI training, knowledge sharing and hands‑on guidance across Python, Linux, data platforms and operational technologies. My focus is connecting domain expertise, engineering practices and AI‑driven approaches into practical, cross‑domain capabilities that reduce operational risk and enable faster, data‑driven decisions.

Value Proposition

Cross-team technical leverage, not just individual execution

Cross-domain technical leverage

Connects traditional and modern Core Voice operations with observability, data engineering, automation, database platforms and AI/MLOps practices to create scalable, reusable operational capabilities.

Operational platform thinking

Builds monitoring foundations, data pipelines, automation workflows and support models used across multiple teams — not isolated one-off scripts.

End-to-end ownership

Manages critical operational components across OS, databases, dashboards, integrations, users, patching, upgrades, vulnerabilities and production support.

Metrics into decisions

Transforms raw Core Voice measurements into structured KPIs, dashboards, aggregations and actionable operational intelligence.

Reduced escalation dependency

Resolves complex Grafana, database, Linux and monitoring issues internally, reducing delays, vendor dependency and operational friction.

Team enablement & knowledge transfer

Delivers ML/AI training, technical guidance, hands-on support, documentation and practical enablement across Python, Linux, data platforms and operational technologies.

Core Pillars

One mission, multiple technical foundations

Telecom Domain Authority

Deep Core Voice expertise across IMS, SDVoice, SIP/Diameter, core applications, access, roaming, alarms and operational troubleshooting — connecting telecom domain knowledge with modern engineering practices.

Observability & Operational Intelligence

Design and support of monitoring platforms, Grafana Enterprise dashboards, KPI models and near real‑time visibility that strengthens decision‑making and operational readiness across critical network functions.

Data Engineering & Platform Reliability

Python ETL pipelines, PostgreSQL/TimescaleDB, MySQL 8, MongoDB and InfluxDB engineering, metric normalization, storage, aggregation, analysis, upgrades, patching and vulnerability handling for reliable operational platforms.

MLOps & AI‑Driven Operations

Contribution to MLOps initiatives, anomaly detection concepts, AI‑assisted operational workflows and practical ML/AI training that accelerates adoption of intelligent automation within telecom operations.

Platforms & Projects
