Most software projects don’t fail on technology. They fail on translation: what the business needed never quite made it into what got built. I close that gap by being the same person in the requirements meeting and in the code.
I’m Tony Mercado, founder of MercTech. I’ve spent 20 years building production systems, from startups to enterprises processing hundreds of millions of dollars in transactions. When you hire MercTech, I’m in the work: writing the code myself on focused builds, leading a senior engineering team on larger ones.

Fixed bid, not an open meter
You’ll know the cost before we start. I put the scope in writing, price the outcome, and tie payment to delivery milestones. Estimates are my risk to carry. That discipline is why clients keep coming back with the next project.
The stack
PHP, Python, and Node.js on AWS, with Terraform managing the infrastructure underneath. I build for the team that will maintain the system, so the code ships documented, tested, and deployable from day one.
Based in Winter Park, serving Orlando and remote teams across the US.
