SharpDuel

SharpDuel is a sports betting and fintech marketplace, and Dan was its founding CTO. The market window was tight, so the first job was speed: the MVP shipped in 6 weeks, with the core product, payment integration, and user testing all landing inside that window. From there the backend had to hold up under real growth, a multi-tenant architecture built for high concurrency and real-time updates, payment and settlement systems handling real money, and admin tooling that let the team run the platform without adding headcount to match the user base. The platform reached $200K in monthly recurring revenue within 4 months of launch.

• The market window was tight and a slower launch meant a competitor could capture the users first, so speed mattered as much as correctness
• The platform had to process real-time odds and match data at scale from the very first release, with no room to defer it
• Multiple B2B clients needed to run on the same backend without one tenant's load or bugs touching another's
• Payment and settlement logic had to be correct from the first dollar, since it was handling real money through a subscription and betting platform

• Built and shipped the MVP in 6 weeks: the core product, payment integration, and user testing, all inside that window
• Architected the multi-tenant backend so B2B clients ran on shared infrastructure built for high concurrency and real-time updates
• Built the payment and settlement systems and the real-time match flows the platform's revenue actually ran through
• Built ops automation and admin tooling so headcount did not have to scale in step with the user base
• Made the early technical calls that let the team keep shipping instead of rebuilding the backend at month nine
• Carried the platform from that 6-week MVP to $200K in monthly recurring revenue within 4 months of launch

Daniel delivered an MVP in 6 weeks that became a $200K/month business.
