About Me
AI researcher turned Riverside web developer.
I’m Sebastian Gabarain, founder of Weblocks Riverside — a Riverside, CA web design company offering custom web design, web development services, and website redesign for local service businesses. I build high-performance websites and local search systems using principles drawn from machine learning, technical SEO, and modern web engineering.

The Background
Engineering better local web infrastructure.
My background in machine learning and open-source AI research shaped how I approach web performance, search systems, and technical problem-solving.
Many businesses across Southern California are still using slow, outdated websites that struggle to rank, convert, or communicate trust effectively. Weblocks Riverside was built to bring modern web engineering principles to local service businesses that have historically been underserved by bloated agency templates.
Instead of relying on drag-and-drop builders, I focus on lightweight architecture, frontend performance, and semantic structure. The goal is to provide local businesses with technically efficient websites that serve as genuine assets for growth.
Research & Open Source
Before focusing entirely on web infrastructure, I founded the M4-ai research lab, working on model experimentation, open-source datasets, and AI architecture. This analytical training forms the foundation of my technical expertise. My independent research and AI models have been cited in over 25 published research papers by the global scientific community.

Operating principles
01
Local businesses come first.
I partner with local businesses focused on long-term growth and measurable outcomes.
02
Logic over guesswork.
Search is increasingly semantic. I approach local SEO as systems architecture—relying on structure, technical precision, and data.
03
Ownership & transparency.
Your domain, analytics, and website assets remain yours at all times. No vendor lock-in, just transparent technical partnerships.
Philosophy
How I think about web design & search systems.
Search is increasingly semantic.
Google doesn't just match keywords anymore; it evaluates semantic structure and entity relationships. My background in ML helps me architect technical SEO and content structures built for modern search retrieval.
Speed affects trust and conversion.
Slow sites lose customers before they even load. I use a modern development stack and performance-focused engineering to ensure your site passes Core Web Vitals and provides a frictionless user experience.
Local SEO is systems architecture.
Ranking locally isn't magic; it’s about clean code, robust structured data, and building technical authority. I treat your local search presence as a digital system that requires maintainable, logic-driven architecture.
Websites should support business outcomes.
A website is not a digital brochure—it’s business infrastructure. Every structural decision is optimized around generating booked jobs, inbound calls, and measurable growth for your service business.
