Dear Startup Founder, I understand Startup is like jumping off the cliff and then building a parachute before you hit the ground It is challenging and not everyone's cup of tea I know you are worried about risking your hard-earned money on a product that you think can change the WORLD we breath in Anxious, anguish, tossing and turning in your bed at 3 AM And to take it one step further You are being handicapped and throat grabbed by a zillion of directions and scepticism OMG! Is the new idea big enough to matter? Can I leanly test it and quickly find out if it's viable? What problems can I solve that my competition cannot? What's the opportunity cost? How can I measure success—and failure? ..... Ugh!!!! and list goes on disrupting your neocortex and limbic cells! BUT “The people who are crazy enough to think they can change the world are the ones who do.” - No Surprises! Now Look, Dear Startup Founder, Are you also the one with a bad case of shiny object syndrome?

If your technical infrastructure is hitting a ceiling—or if your lead flow has 'leaks' you can’t identify—you don't just need a line-coder; you need a Strategic Engineering Partner who writes scalable architecture. I help $1M+ revenue organizations bridge the gap between business goals and technical reality. I don't just build websites; I engineer Revenue Engines. Whether you’re struggling with a legacy Drupal/Magento stack or scaling a modern React/Node app, I provide the oversight to ensure your tech is an asset, not a liability. How I drive value as your Fractional CTO: - Conversion Infrastructure: I identify the "dead ends" in your user journey. Using GA4 Path Exploration and Technical SEO, I ensure your site actually captures and syncs the leads your marketing team is paying for. - CRM & Pipeline Integration: Expert-level synchronization between your CMS (WordPress, Drupal) and your CRM/Lead tools (Pipedrive, Salesforce, Zapier, Mailchimp). No lead falls through the cracks. - Legacy Modernization: I specialize in the "high-stakes" maintenance of aging enterprise systems, ensuring security and performance while planning a strategic path to modern architecture. - Technical Stewardship: I own the roadmap. I manage the AWS/DigitalOcean infrastructure, oversee CI/CD pipelines, and ensure your code is documented, scalable, and built for growth. Core Expertise: - Full-Stack: PHP (Laravel, Zend), Node.js, React, MySQL/MariaDB. - Enterprise CMS: WordPress (Expert Custom Development), Drupal 7/9/10. - DevOps/Cloud: AWS (Lambda, S3, Amplify), DigitalOcean, Docker, Jenkins. - Growth Tech: Technical SEO, GA4 Audit, GTM, Conversion Rate Optimization (CRO). If you are tired of "developer ghosting" and want a partner who understands your P&L as well as your code, let’s talk.
