I already have a trained machine-learning model sitting in a repo; now I need it running reliably on AWS. Your first task is to containerise the model (Docker) and spin it up on an AWS EC2 instance—the environment I’ve chosen for this project. Once it is live, expose a secure REST endpoint so my application team can POST data and receive predictions in real time. Low latency matters, so please size the instance with that in mind and configure autoscaling policies if you feel they will help. Model quality can drift, so the next priority is a solid monitoring stack. I want to see Accuracy, Latency and Error rate streaming into CloudWatch (or Grafana/Prometheus if you prefer) with clear dashboards and alarms that alert us when thresholds are breached. Feel free to add extra me...

I’m bringing in an external expert to tighten up a mixed-vendor environment that spans Cisco, Juniper, HPE/Aruba switching and a FortiGate firewall. Most of the day-to-day items run well, yet lingering issues around VLAN design, trunk consistency, OSPF versus static routes, and a few NAT quirks at the edge are starting to show. The single highest-value task is establishing a reliable Site-to-Site VPN between two offices so we can retire an aging MPLS circuit. Beyond that, I’d like you to review current firewall rules, clean up redundant objects, and confirm that inter-VLAN routing on the switch stacks lines up with our security zones. SolarWinds is in place for monitoring; if you see gaps in SNMP polling or alerting, feel free to tune those as you go. To keep expectations c...

Our VMware Cloud Foundation 9 deployment is ready for its management-domain build and I need the underlying network finished off quickly and cleanly. The hosts sit on Aruba switches, and the remaining tasks centre on switchport updates, IP/DNS adjustments, and a complete firewall rollout so the VCF bring-up checks pass first time. Work to be completed • Aruba switchports: create or modify trunks/access ports, tag the correct VLANs for Management, vMotion, vSAN, NSX-Edge and future workload domains, then document every change. • IP addressing: finalise the allocation plan, reserve management ranges and update any DHCP scopes. • DNS: add the A/PTR records for SDDC Manager, vCenter, ESXi, NSX and support services so name resolution works end-to-end. • Firewall: im...

Our users have now moved to Windows 11 and I need an experienced hand to keep them productive. Day-to-day you will troubleshoot any workstation issue—slow logons, driver conflicts, blue screens—and close it out with clear, concise documentation. Alongside the endpoint work, I rely on an on-premises Microsoft Exchange environment. You will diagnose mail-flow problems, adjust mailbox quotas, manage backups, and apply cumulative updates without disrupting service. Because our deskside tickets often bleed into hardware faults and occasional wiring or switch-port hiccups, you must also be comfortable swapping parts, tracing cables, and restoring connectivity when a PC, printer, or access point drops off the network. Deliverables (all ticket-driven): • Resolved Window...
