What I'm looking for

I'm looking to contribute to a B2B SaaS engineering team where I can build high-performance React and full-stack products, solve complex data-visualization challenges, and collaborate closely with product, design, and backend teams.

With over 5 years of experience specializing in B2B SaaS Startups in front-end and full-stack development—primarily using React.js, TypeScript, JavaScript, and Node.js—I am confident in my ability to add immediate value to engineering teams. During my tenure at Factors.AI, I successfully improved web application load times by 30% and engineered reusable UI components, optimizing data-intensive visualization tools.
