I’m a seasoned Full Stack Engineer with over eight years of hands-on experience in designing, building, and scaling software solutions across logistics, e-commerce, and SaaS industries. Alongside deep technical expertise in the MERN stack, React Native, and Spring Boot, I bring a strong track record of technical leadership—mentoring developers, driving system architecture decisions, and ensuring delivery of reliable, high-quality products. In my most recent role at Code Charley, I led a team of engineers in developing logistics and CRM platforms used by over 10 enterprise clients. I was responsible not only for the technical direction but also for improving team workflows, introducing CI/CD pipelines, and reducing deployment times by nearly 50%. These systems supported 100,000+ active users and helped improve delivery efficiency by 25%. Earlier at Poshmark Pro Tools, I helped scale our automation platform to support thousands of sellers, while fostering best practices that improved team productivity and code quality. What sets me apart is my ability to balance hands-on coding with technical leadership. I take ownership of my work, communicate clearly with both technical and non-technical stakeholders, and stay focused on delivering scalable solutions that solve real business problems. Whether it's leading a sprint, reviewing architecture, or rolling up my sleeves to solve a production issue, I bring consistency and accountability to the team. Thank you for taking the time to review my background. I’d welcome the opportunity to contribute my experience and leadership to a team where reliability, innovation, and collaboration are valued.
