Technical Architect

Your tasks

Job overview Map the environment: servers, domain, network, firewalls, DNS and certificates. Find every background process: Windows services, Task Scheduler jobs, SQL Agent jobs, scripts and batch files. Work out what each job does, when it runs, and to which systems it connects. Trace network traffic to identify all inbound and outbound connections (APIs, SFTP, file shares, database links). Review IIS setup, service accounts, permissions and security exposure — the portal is publicly reachable. Check backups and help set up a safe copy of the environment for analysis. Produce the infrastructure document, network diagram, batch job catalogue and runbook. Work read-only on production and report progress daily.

Month 1 Get access. Find every server, service, scheduled job and network path behind the application. Deliverables: Infrastructure inventory, first network diagram.

Month 2 Trace what each background job does, when it runs, and to which systems it talks. Deliverables: Batch job catalogue, integration flows at network level.

Month 3 Validate findings, close gaps, and hand over the full picture. Deliverables: Infrastructure document, network topology, runbook, risk register.
