I've built payment orchestration, lending, HR, and AI-powered systems across MyDevConnect, Really Great Tech, and Progpharma Digital. At MyDevConnect, I architected a multi-provider payment orchestrator that achieved 99.9% uptime and 95%+ transaction success across six providers.

I refactored PCX's payment routing service into a modular Clean/Onion architecture supporting 12 providers and 30+ API endpoints, while building a no-code routing configuration UI that removed the need to deploy routing changes. I also designed RBAC across 12 intercommunicating services and built payment-link infrastructure that cut payment initiation time by 70%.

At Really Great Tech, I led automation for an HR management platform serving 100+ users, reducing onboarding from three hours to 30 minutes and saving more than 20 HR hours weekly. I've also delivered React and TypeScript products spanning 3D building verification, DeFi sports betting, and responsive risk-assessment tooling.

Outside client work, I build practical full-stack products such as a RAG-powered portfolio backend, an employee scheduling system, and an AI puzzle platform that served 1,103 concurrent users. I care about maintainable architecture, reliable delivery, and systems that create measurable business impact.
