PORTFOLIO

A curated showcase of production applications, enterprise web platforms, and generative AI systems engineered for velocity and scale.

ABOUT ME

I am a Full-Stack Product Engineer at Mercury Sols and the Founder of RafayLabs. With deep hands-on expertise across modern web and cross-platform mobile ecosystems, I specialize in taking digital products from zero to production.

By combining scalable software architecture (React Native, Next.js, NestJS) with cutting-edge AI-assisted workflows, I build high-performance applications with startup velocity and enterprise reliability. When I am not architecting digital solutions, I am researching emerging generative models and experimenting with AI agents.

01

DESIGN

UI/UX & Product Design

I design intuitive, user-focused experiences for mobile and web applications. From user flows and interactive Figma prototypes to scalable design systems and pixel-perfect interfaces, I create experiences that are clear, engaging, and built around real user needs.

DEVELOPMENT

Full-Stack Web & Mobile

I build robust, production-ready applications across mobile, web, and backend platforms using React Native, Next.js, and NestJS. I focus on clean architecture, scalable code, performance, and reliable API integrations to turn ideas into complete digital products.

QUALITY ASSURANCE

Testing & Reliability

I validate applications across mobile, web, and backend environments to ensure reliability, usability, and production readiness. From functional and regression testing to API validation, release verification, and real-device testing, I identify issues early and help deliver stable, high-quality products.
