Najmaz Sakib

Senior Engineer – Service Assurance

Infozillion Teletech BD Ltd

• Own L1/L2 incident management in a 24/7 production environment — from first alert to root cause, with structured escalation that keeps noise low and resolution fast.
• Monitor system, application, and network health across the stack using ELK Stack, Grafana, and Nagios; built custom dashboards that surfaced failure patterns previously invisible to the team.
• Lead investigation of A2P SMS delivery failures — correlating application logs, network traces, and telecom operator data to isolate root cause under time pressure.
• Reduced mean incident response time by standardising log triage workflows; what took 40 minutes now takes under 15.
• Authored and maintains the team's internal runbook library — structured so that a new engineer can handle critical incidents without tribal knowledge.
• Coordinate directly with telecom operators during outages, translating technical findings into clear, actionable communication across teams.
