    Over the past fifteen years as a technology consultant, I’ve delivered many services and tackled thousands of troubleshooting and security-related tickets. My twelve-year tenure at Dell SecureWorks, working in eight different roles, involved managing cybersecurity for clients worldwide and contributing to numerous high-impact projects. These experiences inspired me to develop FixFinder, a software product that enhances service efficiency through self-help IT tools. As a long-time UpWork client, I value transparency and honesty. I’ve often encountered freelancers who claimed they could handle everything but lacked depth. I understand the importance of hiring someone who can consistently and successfully tackle challenges without a steep learning curve. As a freelancer, I commit to billing only for the hours worked, never padding time entries or idling on your hard-earned money. I believe in scoping work clearly with clients from the start—determining requirements, organizing resources, and planning our approach to accelerate progress and reduce surprises. While I’m adaptable and can work with less initial information, I prefer to keep processes transparent and structured. My deep technical intuition, developed through professional services and ongoing support for my companies and others of all sizes, is complemented by a relentless work ethic. I’m adept at auditing systems, securing environments suitable for small to enterprise-level operations, and employing a business-savvy approach without overwhelming clients with technical jargon or excuses for not producing results. In my hands-on technical work, I focus on eliminating surprises, clearing obstacles, and resolving issues swiftly and thoroughly. I provide detailed reports on problems and strategize preventive measures to mitigate future complications. Whether leading a team or working independently, I tailor my approach to meet project demands effectively. Having managed numerous migrations for remote, on-site, and hybrid setups, I know the nuances of planning, communication, preparation, execution, and ongoing support. I aim to teach my methodologies, help organize our efforts and ensure alignment at every step. I seek opportunities to build trust and mutual growth with introspective clients. Things I promise never to do: • Undermine you in front of your employees or clients. • Expose your environment to apathy and neglect. • Misrepresent problems, challenges, or progress. • Exaggerate my skills or abilities to gain profit. • Outsource any of my work to others. • Attempt to solicit your employees, clients, vendors, etc. What I like about my clients: • Mutual Effort in Scoping: Helps avoid misunderstandings and ensures a smooth project. • Realistic Expectations: Ensures quality work without undue stress, neuroticism, etc. • Respect for Expertise: Trusting experts to execute smooth transitions and avoid pitfalls. • Engagement: Active involvement keeps the project aligned and progressing. • Understanding of Complexity: Recognizing IT challenges helps manage expectations. • Appreciation for Effort: Acknowledging hard work creates a positive environment. • Ethical Practices: Valuing honesty and integrity builds a trustworthy relationship. Powered by #actualintelligence Vendors, tools, and platforms I have mastered, trained others on, supported in production, and migrated to/from. I also excel at quickly ramping up on similar tools: AFI.AI Airtable Aruba Autotask Avanan Azure Barracuda BitDefender BitTitan Bloomfire Box.com Bolt.new Calendly Carbon Black Cisco Security Citrix CloudAlly Cloudflare ConnectWise Confluence Crowdstrike DataDog Dell DMarcly DNSFilter Docker Dropbox Duo MFA Datto RMM Famous Server Fortinet Google Cloud Google Workspace GoDaddy GitHub Hyper-V InTune Involv Intranet IT Glue JIRA Juniper SRX Kaseya Products Kernel Migrator Keeper LastLine LastPass Lenovo METRC Meraki MigrationWiz Mimecast Microsoft Defender Monday Mover MoveBot Ninja RMM N-Able N8N NoCoDB Okta Panda Pantheon PagerDuty Palo Alto Pillr Prismatic Product Board Remedy Replit Rocket Cyber Salesforce SendGrid SentinelOne ShareGate SiteGround Snort Sonicwall Sourcefire Splunk StackPath Sucuri Taegis EDR Teams TeamWork Trend Micro Umbrella Ubiquiti Webroot WebTitan WPEngine WordPress Zapier Zoom --- 'No Feedback' Note: This happens when clients become unresponsive during consultations or contracts, not due to dissatisfaction. I end these on my side with positive feedback to keep my profile up to date. ---

    I am a security-driven individual with intimate knowledge of various security solutions and best practices, primarily the full Sophos suite of security offerings, including next-gen firewall appliances, XDR/MDR, and MDM. I also have experience working with and/or reverse-engineering Fortinet, Ubiquiti, Aruba, Palo Alto, and Cisco products. I am a quick learner and an on-the-fly thinker and I thrive by learning and adapting while I work. My love for puzzle solving fuels my interest in infrastructure design/improvements, and I have worked on infrastructures across several different platforms, including Azure, AWS, MS Hyper-V, VMWare, and Nutanix. My drive to constantly improve my surroundings has resulted in being recognized as a crucial resource at my current position, to the point that I was able to collaborate with the leadership at my current company to create my current role as Service Desk Manager, where I have made numerous measurable improvements to the overall operation of the company.
