What I Do
From Idea to Product
Got something brewing? I take concepts from whiteboard to working software, handling product decisions, technical architecture, and execution in a single engagement. You bring the vision. I make it real.
Full Stack Development
React, Next.js, Node.js, and everything in between. Production-grade code that scales and hands off cleanly. No shortcuts, no technical debt handed over at the end. Built right the first time.
AI Integration & Enablement
I built techstax.io to help businesses move from AI curiosity to AI capability. Custom LLM integrations, intelligent workflows, and the product thinking to make it stick. Not AI for the sake of AI.
techstax.ioBubble.io to AI-Ready Codebase
Heavily invested in a Bubble app that's hit a ceiling? I migrate Bubble.io apps to a modern, owned codebase — without losing what you've built. The result: a foundation that's hireable anywhere, scales with your business, and is ready for AI-powered development. You bring the app you outgrew. I deliver the one you'll grow into.
See how it worksNo-Code to Code
Softr, Make.com, Webflow, Glide, Airtable — they got your idea live. Now they're holding it back. I migrate no-code and low-code platforms to a real, owned codebase: preserving what you've built, removing the ceilings, and giving your product the foundation it actually deserves.
See how it worksVibe-Code to Production-Ready
You shipped something real with Cursor, Claude, or Lovable — fast, scrappy, and it works. Now it needs to survive real users, real load, and a real team. I take vibe-coded apps and harden them for production: proper auth, error handling, test coverage, CI/CD, and a codebase the next developer won't dread inheriting.
See how it worksFractional CTO/Tech Lead
Your product, always in capable hands. $4,995/month — flat, predictable, pauseable. Includes 10 hours of development, hosting management and monitoring, DevOps, emergency production support, and security operations. Senior technical leadership without the full-time headcount.

“Marc has a rare combination of technical depth and product intuition. He didn't just build what we asked for, he pushed back when it mattered and shaped something much better than we'd spec'd.”
“Working with Marc felt like having a co-founder in the room. He understood the problem before we finished explaining it, and the execution was flawless.”
“Marc is extremely collaborative, accommodating, and devoted. He is an all-around lovely person to meet and work with and was highly motivated to understand our specific needs for the web app we were creating. He was patient with us and always made time to fix bugs, often making improvements beyond our initial ask. He also spent time clearly explaining coding and programming concepts to build our independence with programming tools. Marc helped us create a beautiful product that we were able to launch and now have users joining! You'll be in excellent hands with Marc and his team. Can't recommend him enough!”
