I’m a Senior full-stack developer with 9+ years of experience specializing in web development. I focus on designing and shipping scalable, high-performance systems while improving latency, reliability, and day-to-day developer productivity.

At Corevia, I led development of a gaming platform used by 50,000 users, cutting page load times by 40% and increasing session time by 25%. I built RESTful APIs supporting over 1M transactions/month and helped drive 99.99% uptime by streamlining game data and user session handling. I also integrated third-party APIs for external data and payments, reducing manual operations by 40%, and managed deployments with Docker and Kubernetes to achieve 99.9% uptime during peak traffic.

Previously at NodeCrest, I implemented secure authentication and Stripe payment gateway integrations, reducing failed transactions by 30% and strengthening user trust. I optimized platform performance to reduce loading times by 40% and built a cross-platform React Native mobile app downloaded over 100K times with a 4.8-star rating on iOS and Android. On the backend, I expanded services using Node.js and MongoDB to support 100K users and millions of dollars in transactions, plus real-time updates that increased engagement by 20%.

Earlier, at BlockHarbor, I led backend services for a real-time voting system with under 10ms latency, handling over 100,000 votes per minute during peak hours. I secured sensitive data with advanced database management and RBAC authorization, meeting GDPR compliance standards, and improved a live election dashboard with 100% uptime for high-traffic events. I’m motivated by cross-functional collaboration, disciplined engineering practices, and delivering measurable impact through modern web technologies.
