CTO & Technical Founder From Code to $200K MRR
I'm Daniel Haynes, a CTO and technical founder based in Charlotte, NC. I've taken products from napkin sketch to $200K in monthly recurring revenue, helped secure $1.5M in seed funding, and built systems serving over 1 million customers.
Platform scaled in 12 months

MVP to production
Production systems I've architected maintain industry-leading reliability, ensuring users always have access when they need it.
Achieved through redundant architecture, automated failovers, comprehensive monitoring, and infrastructure-as-code practices.
My work spans the entire product lifecycle: from system architecture and infrastructure to team leadership and business strategy. I've written code that processes millions of transactions, designed hardware that ships to customers, and led engineering teams that deliver under pressure.
Based in Charlotte, NC, I'm currently Founding CTO at SharpDuel, leading everything from architecture decisions to scaling infrastructure to building high-performing teams.
From database schemas to pixel-perfect UIs
Designing for millions of users
Multiple successful ventures and exits
From MVP launches to enterprise systems, here's a look at products I've built from the ground up.
Took a startup from early stage to over $1M in annual revenue. Led a team of 10+ engineers, architected scalable systems on AWS, and engineered solutions that serve over 1M customers.
Led end-to-end product development of a smart cold plunge system, combining IoT hardware, embedded firmware, ML-powered recommendations, and mobile app integration.
Built the MVP in just 6 weeks and scaled the platform to handle explosive growth. Architected a multi-tenant backend capable of supporting high concurrency and real-time updates.
Built an online marketplace that matches buyers and sellers for 3D printing services. Took the product from initial concept to production deployment in just 3 weeks, acquiring 100+ users within 2 days of launch.
Built a real-time Amazon price comparison tool that calculates true price-per-unit by parsing product titles for quantities and integrating with Amazon PA-API 5.0. Implemented intelligent pattern matching with context-aware logic for edge cases like multipack equivalencies and hybrid pricing.
Built a React frontend for an MLB NRFI prediction tool featuring game simulations with probability meters, EV calculations, and Kelly criterion bet sizing. Added backend rate limiting with slowapi to protect against abuse, bringing existing code to production readiness.
Built a comprehensive platform that aggregates and categorizes developer tools, making it easy for teams to discover the right solutions. Implemented SEO automation strategies that drove organic growth to 100K+ monthly users.
A decade of building has given me a diverse toolkit. Here's what I bring to the table.
Senior-level execution without the agency markup. You're paying for engineering, not account managers, office space, or layers of overhead.
From idea to paying customers
Get to market fast with a production-ready MVP. I've shipped products that reached $200K MRR -bringing the same battle-tested approach to your startup.
Technical leadership without the full-time salary
Strategic technical guidance, architecture decisions, and hands-on execution. Get CTO-level expertise on a retainer basis.
Rescue your legacy systems
Your outdated infrastructure is costing you money and speed. I'll migrate, optimize, and future-proof your backend.
Full-stack, fully yours
Production-ready applications built by someone who's scaled them to millions of users. React, React Native, Node.js -your stack, done right.
No account managers, project coordinators, or office rent baked into your bill. Just engineering.
Talk directly to the person writing the code. No telephone game, no handoffs to junior devs.
Charlotte, NC. Real-time collaboration, same-day responses, no 12-hour delays.
"Daniel quickly dissected and truly understood my idea, then turned it into a polished, working web app with a clear and thoughtful approach. Communication was always excellent, timely, detailed, and easy to follow.
If you have the opportunity to work with Daniel, take it - you won't regret it!
"I shared an idea with Daniel for an MVP. He took that concept and implemented the necessary APIs and tooling, enabling a solid public-facing MVP to be launched significantly faster than anticipated.
Will be using him going forward as we expand on this project.
"Daniel completed our project quickly, with the utmost professionalism and knowledge. We highly recommend him.
We will rehire him when we need expert level support.
I take on select projects where there's room to do things right-typically starting at $2,000. Tell me about what you're building.
