I recover, fix, build, design, and maintain cloud infrastructure in live production environments. You work directly with me: no agency layer, no account manager, no handoff. The person who reviews the logs, reads the headers, checks the DNS, inspects the IAM policies, and plans the change is the same person you talk to. Two reasons clients usually hire me: 1. Recovering failing infrastructure Cloudflare rules blocking real users; DNS resolving differently across regions; Microsoft 365 mail flow breaking; SPF/DKIM/DMARC failing; Conditional Access locking users out; a high-volume sending platform landing in spam or its sender reputation collapsing; AWS environments drifting; or infrastructure becoming too risky to change safely. 2. Prevention When they want the environment built properly before it becomes too expensive to fix: secure identity, segmented infrastructure, controlled deployment pipelines, logging, monitoring, rollback procedures, and operating standards that hold up in production. Most engagements begin with a specific problem, then move into hardening, documentation, automation, governance, and reducing reliance on manual fixes. I bring 15+ years of experience across pharma, aviation, SaaS, MSP, startup, and Fortune 500 environments. My certifications include AWS Certified Solutions Architect Professional, AWS Certified Security Specialty, Terraform Associate, Microsoft 365 Enterprise Administrator Expert, MCSE Cloud Platform and Infrastructure, and Azure Architect. What I build and fix - Cloudflare and web infrastructure: WAF tuning, bot and DDoS mitigation, rate limiting, DNS, TLS, Workers, KV, Zero Trust, Access, WordPress and WooCommerce performance, hardening, malware cleanup, Linux, Nginx, Apache, and Docker. - AI and agentic infrastructure: LLM pipeline design and deployment (Anthropic, OpenAI), FastAPI and Python services, RAG, structured output, MCP server builds, prompt orchestration, evaluation and QA gates, API integration with Shopify and business systems, secure secrets handling, and VPS deployment on Hetzner and AWS. - Microsoft 365 and identity: Entra ID, Conditional Access, MFA, app registrations, least-privilege design, Defender for Office 365, audit logging, Exchange Online, hybrid mail flow, Intune, and GDPR-aligned tenant design. - Google Workspace security, governance, and migration: security reviews, identity and access controls, domain and tenant migrations, Shared Drive architecture, Gmail mail flow recovery, and evidence-based administration. - AWS infrastructure and security: VPC segmentation, IAM design, EC2 and RDS hardening, CloudWatch, GuardDuty, KMS, secure logging, and landing zone patterns. - Email deliverability and sending infrastructure at scale: SPF, DKIM, DMARC alignment and enforcement, header analysis, reputation recovery, SMTP relay, and coexistence across Google Workspace, Microsoft 365, and Postfix. Sending-platform infrastructure (Klaviyo and similar): deliverability diagnosis, sender reputation recovery, list and segment architecture, bounce and complaint forensics, ingestion-pipeline and API integration review, and warmup/scaling for high-volume senders. How I work No blind changes in production. Before changing anything, I review the evidence: logs, DNS behavior, headers, API output, IAM policies, live configuration, and operational risk. Changes follow ITIL methodologies and are planned, staged, documented, and, where possible, reversible. You get a clear record of what changed, why, which risks were reduced, how to roll back, and what to monitor afterwards. Message me if you need a senior independent consultant who can take ownership of your cloud infrastructure issues, without an agency layer between you and the work.

What does an Adguard specialist do?

An Adguard specialist configures and manages AdGuard Home to enforce network-wide DNS filtering that blocks ads, trackers, and malicious domains. This role focuses on deploying the software as a local DNS resolver and maintaining the rule sets that determine which internet traffic reaches client devices. The specialist ensures that every device on the network routes its DNS queries through the AdGuard server for consistent protection.

  • Installs and configures AdGuard Home on a server or container to act as the primary DNS resolver for the local network. This setup involves binding the service to the correct network interfaces and securing the admin panel with strong credentials. The specialist verifies that the service starts automatically after reboots to maintain continuous protection without manual intervention.
  • Manages DNS filter lists and writes custom filtering rules to block specific domains or allow trusted sites. This work includes selecting built-in filter subscriptions, such as the default AdGuard DNS filter, and adding third-party blocklists for enhanced coverage. The specialist tests rule syntax to prevent accidental blocking of legitimate services while ensuring unwanted trackers remain restricted.
  • Configures DHCP and DNS settings to force client devices to use the AdGuard Home server for all domain resolution tasks. This process often involves adjusting router settings or setting static IP assignments to ensure devices cannot bypass the filtering layer. The specialist documents these network changes so other administrators can replicate the configuration or troubleshoot connectivity issues later.
  • Troubleshoots DNS resolution failures and refines exclusion lists when users report broken websites or missing content. This task requires analyzing query logs within the AdGuard Home interface to identify which rules trigger false positives. The specialist adjusts the filtering logic or adds specific domain exceptions to restore functionality while keeping the broader blocking rules active.

How to hire an Adguard specialist on Upwork

Step 1: Post a job

Define your network filtering needs clearly to attract qualified candidates. Use the Job Post Generator powered by Uma™, Upwork's Mindful AI to draft a precise description in seconds. Describe your requirements in a few sentences, and Uma creates a tailored post for this role. You can write a new post, update a saved draft, or reuse an existing one.

  • Specify whether you need AdGuard Home installed on specific hardware or within a container environment.
  • List the types of DNS filters and custom blocking rules required for your network traffic.
  • Detail any DHCP configuration changes needed to route client queries through the AdGuard resolver.

Step 2: Evaluate candidates

Look for proof of experience with DNS-based ad blocking and network configuration. Uma runs instant video interviews and builds shortlists with side-by-side comparisons to speed up your review. Check their work history for successful deployments of AdGuard Home or similar DNS filtering tools.

  • Verify they have configured built-in filters and managed custom host-based allow or block lists.
  • Confirm they understand how to troubleshoot cases where specific domains fail to block or load incorrectly.
  • Check for examples of maintaining filter updates and adjusting rule syntax for complex network environments.

Step 3: Interview your top choices

Discuss their approach to managing DNS resolution and filtering logic. Schedule and conduct interviews within Upwork Messages, which generates an immediate transcript and summary after each session. Focus on their problem-solving methods for network-wide blocking issues.

  • Ask how they handle exclusions for legitimate sites that get caught in aggressive filtering rules.
  • Request examples of custom filtering rules they have written to block specific trackers or ads.
  • Inquire about their process for verifying that all client devices correctly use the AdGuard DNS server.

Step 4: Agree on scope and begin work

Set clear milestones for installation, configuration, and testing. Use Upwork Messages and the contract workroom for communication and project management. Identity verification, payment protection, hourly tracking, and project funds add security to your engagement.

  • Define the deliverable as a working AdGuard Home deployment with active DNS filtering enabled.
  • Require a configured filter set with any necessary custom rules or hosts lists for your domains.
  • Include troubleshooting notes or configuration logs that document how filtering issues were resolved.

Frequently asked questions

Is hiring an Adguard specialist worth it?

For most businesses, yes: hiring an Adguard specialist is worthwhile. This expert configures DNS-based filtering to block ads and trackers across your entire network without installing software on every device. They manage complex filter lists and resolve connectivity issues that generic settings often miss.

How do I evaluate Adguard specialist candidates?

Look for candidates who demonstrate specific experience with AdGuard Home rule syntax and DNS resolution workflows. Ask them to explain how they would troubleshoot a scenario where a legitimate site is blocked by a filter list, as this tests their ability to manage allow lists and custom rules effectively.

What does an Adguard specialist configure on my network?

An Adguard specialist sets up AdGuard Home as your primary DNS server and configures DHCP settings to route client queries through it. They also select built-in filters and write custom rules to block specific domains or ads based on your requirements.

Can an Adguard specialist fix sites that stop loading?

Yes, they identify which filter list blocks the domain and add an exception to the allow list. This restores access while keeping the rest of your network protection active.
