What I'm looking for

I’m looking for a team where I can own front-end architecture, improve performance and accessibility (Core Web Vitals), ship scalable React/TypeScript products, and collaborate tightly with Product/Design/QA while using AI tools responsibly.

I’m a Senior Software Engineer with 15 years of experience, specializing in building scalable, high-performance front-end applications with React and TypeScript. I’m driven by creating responsive, accessible, and performant user interfaces backed by modern APIs and distributed systems, with a strong focus on quality, usability, and maintainability.

Since 10/2021, I’ve designed and built scalable front-end applications at DigitalNebi LLC for teams like Pacific Gas & Electric (PG&E), Apple, and Fidelity Investments, delivering high-quality web experiences across platforms. I translate product requirements, wireframes, and design systems into responsive, accessible UI components that support millions of users, and I own UI architecture decisions including component design, state management, and data-fetching patterns. I integrate with RESTful APIs (handling asynchronous flows, request lifecycles, and error states), optimize rendering efficiency, bundle size, and caching strategies to improve Core Web Vitals, build reusable component libraries for scalability, and use AI-assisted development tools (Copilot and Cursor-style workflows) for rapid prototyping, refactoring, and test generation—while validating for quality and security.

Earlier, I’ve broadened my impact across front-end and supporting full-stack work, including developing modern web applications with React, Angular, and TypeScript, improving performance with code splitting and lazy loading, and contributing to testing and CI/CD pipelines for front-end deployment while mentoring junior engineers. I’ve also led iOS development for customer-facing applications (enhancing performance and user experience) and contributed to cloud service architecture focused on high availability and security, including payment gateway work at AT&T / Total Merchant Services (TMS) centered on security, scalability, and performance. Throughout my career, I collaborate closely with Product, Design, and QA, refine features across browsers and devices, and pair engineering rigor with a practical, delivery-focused mindset.
