MEET THE DEVELOPER
Carlos Kremmer
Founder & Senior Web Developer at GrowLenseI am a web developer with more than 20 years of experience building websites, custom web applications, mobile applications, automation systems and specialized software. My work ranges from customer-facing business websites and e-commerce to fintech tools, APIs, data workflows and algorithmic trading software.
I am also a photographer, videographer and the owner of Photo Studio 308 in TriBeCa, Manhattan. Operating a real customer-facing service business has shaped how I approach development: a website should not stop at looking good. It should make the business easier to understand, generate measurable actions and create a foundation that can improve over time.
That perspective is one of the reasons I built GrowLense—to connect development with search, analytics, measurement and clearer growth priorities after launch.

GROWLENSE-READY DEVELOPMENT
Don't launch a website and then wonder what is actually working.
Eligible builds can launch with GrowLense integration—the business growth intelligence platform I founded to connect development with measurement after launch. It brings search, analytics and local business signals into one workspace so your website can be measured, improved and prioritized after launch instead of becoming a static project that is forgotten.
Build my website + measurement →
Google account permissions and supported data-source access are required for corresponding integrations.
GrowLense recommendations support decision-making; they do not guarantee search rankings, traffic or revenue.
Google Search Console
Understand queries, clicks, impressions, CTR and which pages are already earning search visibility.
Google Analytics
Connect traffic and engagement with website activity instead of reading disconnected reports.
Google Business Profile
Bring local discovery and customer actions into the same growth view when available.
Tracked Website Actions
Measure important website actions such as forms, leads, phone clicks and other configured events.
AI-Assisted Priorities
Turn available business signals into prioritized opportunities and clearer next actions.
Content Opportunities
Identify pages and topics that deserve attention based on connected business and search data.
Action Plan
Move from observation to implementation with recommendations organized around business impact.
Performance Feedback
Measure what changed after implementation so future priorities can be informed by outcomes.
SELECTED LIVE WORK
