STOP HIRING CONSULTANTS WHO ONLY PROVIDE REPORTS. HIRE A COMPUTER SCIENCE ENGINEER WHO ARCHITECTS SOLUTIONS.

In high-stakes digital environments, a list of recommendations isn't enough. You need a Computer Science Engineer with a Master’s Degree who can dive into the database, the server configuration, and the core code to eliminate bottlenecks. I am a Senior Technical Consultant with over 10 years of experience specializing in the intersection of advanced software engineering, technical SEO, and enterprise security.

I don’t just "do SEO" or "manage sites." I apply computer science fundamentals to build, secure, and optimize infrastructures that are designed to scale and rank.

Most SEO specialists stop at the report because they lack the engineering background to implement changes. I specialize in turning failing scores into green passes by optimizing the technical core:

• Core Web Vitals Optimization: Surgical fixes for LCP, CLS, and INP at the code and server level.
• GSC & Crawlability: Expert resolution of Google Search Console errors, sitemap logic, and crawl budget optimization for massive sites.
• Performance Engineering: Advanced Nginx/Apache tuning, Object Caching (Redis/Memcached), and SQL query optimization to ensure sub-second load times.

As an Engineer, I treat WordPress as an enterprise framework. My expertise includes:

• Complex Domain Mapping: Managing hundreds of independent domains within a single network.
• Governance & MU-Plugins: Developing centralized logic to standardize performance and security across the entire network without adding overhead.
• Zero-Downtime Migrations: Executing massive data transitions between Multisite and Single Site environments with 100% integrity.

I am the "Fixer" you call when things go wrong.

• Forensic Cleanup: Deep analysis and removal of malware from files and databases.
• Hardening: Server-level shielding (LFCS Certified) and application-level security to prevent data breaches.
• Data Sovereignty: Strict handling of sensitive information. I am available for NDAs and follow enterprise-grade security protocols.

As a Claude Certified Architect, I integrate AI into the development lifecycle to move with extreme velocity. I build custom AI agents and automation frameworks (Python/Railway) that handle repetitive technical tasks, allowing your team to focus on growth.

• Academic Excellence: M.S. in Computer Science & B.S. in Computer Science Engineering. My solutions are built on solid architectural principles, not just "hacks."
• Scaling DNA: I was the 5th employee at a startup (GrantSolutions) and helped scale its technical foundation as the team grew to 300+ people. I know what 0-to-1 and hyper-growth look like.
• Total Independence: I require zero hand-holding. I analyze the environment, execute the solution, and report results clearly to both technical and non-technical stakeholders.

I maintain a professional schedule that allows for a 4-hour synchronous overlap with PST (California) and full alignment with European business hours. I provide "deep work" during my day and live collaboration during yours.

If you have a complex technical challenge that requires an elite engineering eye, let’s talk.
