Application Monitoring & Observability

Splunk — Data Processing and Data Quality Alerts

• Used Splunk-generated notifications delivered via SMTP email to detect data-loading errors and anomalies in enterprise data processing.
• Investigated mismatches between expected and actual data volumes, including significant increases or decreases in the number of rows or records in Data Warehouse tables.
• Analyzed notifications and relevant logs to identify ETL and reporting issues and support incident resolution.

Grafana, InfluxDB & Prometheus — Monitoring Platform Setup

• Installed and configured Grafana, InfluxDB and Prometheus on a new server as components of an application and infrastructure monitoring environment.
• Supported initial setup and operation of the monitoring stack. Details of exporters, alert rules and dashboards will be documented only if confirmed.

AppDynamics — Windows Monitoring Components

• Installed and configured AppDynamics monitoring components on Windows hosts.
• Configured collection of selected application and system metrics and transmission to a centralized AppDynamics server for visualization and analysis through its graphical interface.

ITRS Geneos — Enterprise Monitoring

• Worked with ITRS Geneos within enterprise application monitoring and production operational support.

Disaster Recovery & Business Continuity

Disaster Recovery Documentation & Planning

• Created and maintained step-by-step Disaster Recovery documentation for enterprise applications, including infrastructure dependencies, installation prerequisites and application recovery sequences.
• Documented how to rebuild and reconfigure applications from scratch after major failures, providing detailed operational instructions for support teams.
• Prepared backup and restoration guidance: required backup types, where backups were stored or retrieved, and how they should be used during recovery.

Manual and Automatic Data Center Failover

• Participated in and performed failover tests simulating the unavailability of a primary data center.
• In manual scenarios, started required services in the alternate data center and restored application operation.
• In automatic scenarios, verified that load balancers redirected service access as intended and that applications became operational in the alternate data center.
• Checked application startup, availability and core functionality after failover; investigated and troubleshot failed starts, connectivity issues and other application errors.
• Validated recovery outcomes and documented steps needed for repeatable future recovery exercises.

Change Management & Application Deployment

Developer Collaboration & Release Preparation

• Collaborated directly with application development teams and participated in Agile development and release activities.
• Received installation and deployment packages from developers and coordinated application changes across development, pre-production and production environments.

Automated Deployment & Verification

• Deployed application updates and release packages to pre-production and production using Bamboo and Jenkins.
• Configured and executed Bamboo deployments with custom runtime parameters and variables; created Bamboo plans and tasks linked to scripts.
• Inspected Bamboo Deployment History step by step, downloaded execution logs and investigated failed deployment steps.
• Monitored application behavior following deployments and troubleshot startup, configuration and runtime issues in collaboration with development teams.

Incident Management & Production Troubleshooting

Application Availability & Service Failure

• Investigated and resolved application incidents in production and pre-production environments, including service crashes, failed application startup and system unavailability.
• Performed application and infrastructure troubleshooting, corrective configuration changes and functional verification following service recovery.

ETL Data Loads & Reporting

• Investigated failed data loads, incomplete or inconsistent data, and unexpected changes in record counts within enterprise data platforms.
• Diagnosed unavailable BI reports and reporting discrepancies involving application behavior, underlying data or database connectivity.

Database Connectivity & Runtime Configuration

• Troubleshot communication failures between applications and databases, including unsuccessful ODBC connections and database access errors.
• Investigated and modified configuration files, environment variables and other application settings as part of incident resolution.
• Validated the affected application and data-processing functionality after corrective changes.

Problem Management & Root Cause Analysis

Recurring Incidents & Problem Records

• Identified recurring incidents and initiated Problem records to investigate systemic issues beyond immediate service recovery.
• Independently performed Root Cause Analysis by examining incident history, application behavior, logs, configurations and system dependencies.

Mitigation, Corrective Actions & Recurrence Prevention

• Documented underlying causes and proposed permanent corrective solutions, as well as mitigating actions to reduce immediate operational impact.
• Worked with colleagues across development, infrastructure and other departments or organizational units to define, coordinate and follow up on preventive actions.
• Focused Problem Management activity on preventing similar incidents from recurring and improving long-term application reliability.
