I need an engineer who can jump straight into my production environment and take full ownership of configuration, ongoing monitoring, and rapid-fire troubleshooting across three key platforms: F5 BIG-IP (with a heavy focus on LTM), Infoblox DDI, and the current fleet of network firewalls. On the F5 side you’ll fine-tune virtual servers, health monitors, profiles, SSL offload, and iRules so traffic flows efficiently and securely. All LTM changes must follow our change-control workflow and be fully documented for audit readiness. Infoblox tasks include cleaning up DHCP scopes, tightening DNS views, creating IPAM automation rules, and setting up alerts that actually matter—no more noise, just actionable events. For the firewalls, I’m looking for policy optimisation, real-time log analysis, and proactive health checks to make sure no unexpected outage or security gap slips through. The current estate is mixed-vendor, so the ability to interpret and refine rule sets regardless of platform is essential. Deliverables • Updated, working configurations pushed to production and backed up in our Git repo • A concise runbook outlining each change, rollback steps, and verification commands • A monitoring dashboard or set of alerts (your choice of tooling) that clearly shows device health, key performance metrics, and security events Acceptance Criteria 1. All new F5 LTM virtual servers pass functional testing with zero packet loss or latency regression. 2. Infoblox DHCP/DNS changes propagate successfully and remain error-free for 48 hours. 3. Firewall rule optimisation yields measurable reduction in rule-hit shadowing and improves throughput without dropping legitimate traffic. If you are comfortable owning these tasks end-to-end and can start soon, let’s move forward.

You need a reliable engineer who can immediately operate inside your production network stack, optimize traffic control, improve security posture, and reduce operational noise across F5 BIG-IP LTM, Infoblox DDI, and mixed firewall environments while keeping everything audit ready and stable. I will approach this by first reviewing your current configurations, change workflows, and monitoring signals, then safely optimizing service delivery without disrupting live traffic. Execution plan Audit existing F5 LTM virtual servers, health monitors, SSL profiles, and iRules, then optimize configurations following your change control process. Deploy updates with backup snapshots stored in your Git repository. Review firewall rule sets across vendors, remove shadowed or redundant rules, and tune logging and monitoring so alerts reflect real risk events. Deliverables will include a production runbook covering change steps, rollback commands, and validation checks, plus a lightweight monitoring view showing device health and traffic behavior. Quick technical question to help me align with your environment. Are you using centralized logging such as Splunk, ELK, or another SIEM platform for firewall and network telemetry? I follow strict production safety discipline. Every optimization will be validated in staging or via reversible configuration changes before touching live traffic.

Hello there, We bring 8 years of experience in network infrastructure automation, DevOps, and monitoring. Your need to eliminate alert noise on Infoblox and build actionable events while optimizing mixed-vendor firewall rules is exactly the signal-vs-noise problem we solve. For Infoblox DDI cleanup, we'd build Python automation that audits DHCP scopes against actual lease data, flags stale entries, and enforces naming conventions programmatically. For firewall optimization, we'd script rule-hit analysis across your mixed-vendor estate to identify shadowed and redundant rules, then quantify throughput gains before and after. We'd use Grafana backed by Prometheus exporters for device health, with custom Python collectors pulling F5/Infoblox/firewall metrics into a single pane — alert thresholds tuned to your baseline, not vendor defaults, so you get signal not noise. Every config change goes through Git with PR-based review and runbooks committed alongside. We've built similar Git-backed pipelines for government platforms serving 25M+ citizens where change traceability was non-negotiable. Assumption: your firewall estate is Palo Alto and/or Fortinet — if different, that shifts tooling but not approach. Week 1: audit, documentation, Infoblox/firewall cleanup. Week 2: monitoring dashboard, alert tuning, and production validation against your 48-hour error-free acceptance criteria. Daily standups or async via Slack, your call. Naveen Brainstack Technologies
