Migrations, advanced technical SEO execution, and full CMS builds — quoted flat-rate, per project. For ongoing small fixes and tickets, see the Technical Retainer instead.
Zero-Drop Migrations & Algorithmic 301 Mapping.
I handle the heavy lifting for risky, large-scale migrations, deploying Python scraping and automated QA to ensure zero lost link equity. Hand over the legacy URL, get back the flawlessly mapped staging link.
Get a Migration EstimateTechnical Takeaways:
- → Algorithmic mapping ensures zero dropped 301s.
- → Automated pre/post Python QA catches 404s before launch.
Spreadsheet Mapping
- Relying on manual Excel data entry leads to human error and dropped link juice.
- Uncovering thousands of hidden 404 errors only after the client site goes live.
Algorithmic Assurance
- 100% programmatic 301 mapping using custom Python scraping architectures.
- Automated pre-launch and post-launch QA scripts. Zero risk to organic traffic.
What your agency actually gets.
Automated QA & Risk Mitigation
I run Python scripts to scrape the legacy site, map every URL programmatically, and test for redirect chains before you ever present the staging link. Your SEO strategy is mathematically protected.
Zero-Babysitting Delivery
No more managing massive spreadsheets or chasing status updates. I plug into your Asana/Slack and deliver the fully migrated, QA'd site on a strict, guaranteed fixed deadline.
Scalable Enterprise Deals
Stop turning away 10,000+ page enterprise migrations because you lack the dev bandwidth. Fixed-scope wholesale pricing lets you confidently say yes to massive retainers and mark up the execution by 50%+.
"They handled our massive E-com migration in 3 days. We handed over the logins on Friday, and it was mapped flawlessly by Tuesday without a single dropped 301."

Enterprise JS SEO & Server-Side Data.
Your strategists run brilliant audits. I execute the fixes — from Server-Side GTM pipelines to custom React "Link Magnets" — unblocking the technical SEO roadblocks your internal team can't touch.
Get a Tech Execution EstimateTechnical Takeaways:
- → Bypass iOS ad-blockers to recover "lost" e-com data.
- → Resolve SSR/SSG JavaScript rendering black holes.
Audit Paralysis
- You deliver brilliant Screaming Frog audits, but the client's internal devs ignore your faceted navigation fixes.
- Ad-blockers and browser cookies erase 30% of your e-com conversion data, making your ROAS look terrible.
Algorithmic Resolution
- I act as your ghost engineering partner, pushing complex JS rendering fixes directly to staging.
- I deploy bulletproof Server-Side GTM architectures to guarantee 100% accurate attribution.
What your agency actually gets.
Complex JavaScript SEO
I resolve heavy DOMs, SSR/SSG rendering bottlenecks, and crawl budget black-holes caused by complex faceted navigation, ensuring Googlebot perfectly parses the content you're trying to rank.
Server-Side Tracking (GTM)
Browser-side cookies are dying. I implement Server-Side Google Tag Manager (GTM-SS) and custom GA4 pipelines so your reporting is immune to ad-blockers and iOS privacy updates.
Digital PR "Link Magnets"
Stop begging for backlinks. I build engaging custom React/Vue calculators, data-viz widgets, and interactive tools that naturally acquire high-DR links from top-tier publications.
"Our client's browser-side tracking was blocking 30% of conversions due to ad-blockers and iOS updates. Rootvertex deployed a custom Server-Side GTM container in 5 days. Our reported ROAS jumped instantly."

Unreliable freelancers destroy your margins. Fixed-scope pricing delivered on exact deadlines lets you confidently mark up the build by 40-60%.
