What I Do
(01)
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.
(02)
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.
(03)
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.

What Clients Say
“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.”
“We went from a rough idea to a working product in six weeks. Marc kept the scope focused, the communication clear, and the code clean. Would work with him again without hesitation.”
