About

I’m Carlos Kremmer, a senior web developer and business owner with 20+ years of experience building and maintaining PHP/MySQL applications, WordPress solutions, and database-driven websites. I combine hands-on development with real production troubleshooting—fixing issues, improving performance, and wiring analytics and conversion tracking so the business can make confident decisions.

I also build AI-assisted workflows, including local large language model inference and background processing, through my platform GrowLense. GrowLense connects performance data from Google Search Console, GA4, and Google Business Profile to generate recommendations, guide implementation, and measure results over time—turning connected signals into continuous growth.

GrowLense — AI-Powered Business Growth Platform

I founded and developed GrowLense, an AI-powered SaaS platform that helps businesses turn their website and Google performance data into practical growth actions. The goal was to connect analysis with implementation and ongoing measurement, giving business owners a clear process for improving their online presence. As the platform’s developer, I built: Custom PHP/MySQL backend functionality, dashboards, and reporting workflows. Integrations with Google Search Console, Google Analytics 4, and Google Business Profile. AI workflows that analyze performance, prioritize opportunities, and generate actionable recommendations. Background workers running across local and cloud environments for automated AI processing. WordPress and StudioCMS connectors that support website improvements and performance tracking. Content validation, revision workflows, and image optimization functionality. Measurement tools that track completed actions and use results to inform future recommendations. The result is an operational platform built around a continuous cycle: connect data, analyze performance, recommend actions, guide implementation, measure outcomes, and learn from the results. This project demonstrates my experience in full-stack development, AI integration, database design, automation, analytics, and production infrastructure. Website: https://www.twine.net/signin
