About

I’m an Engineer who gets things done — end to end. I have 5+ years of experience building and scaling SaaS and AI-powered products in startup environments. My work goes beyond writing UI code: I actively contribute to product ideation, MVP validation, performance optimization, analytics, and deployment. I specialize in: - React & Next.js ecosystems - High-performance frontend architecture - Core Web Vitals & SEO optimization - LLM-based and AI-driven applications I’ve built real-time AI interview platforms, quiz-generation tools, internal products that reduced costs, and multiple growth-focused experiments using A/B testing and analytics. Tech I work with regularly: JavaScript (ES6+), TypeScript, Python, React, Next.js, TailwindCSS, Node.js, REST & GraphQL APIs, Prisma, Supabase, MySQL, PostgreSQL, MongoDB, OpenAI APIs, WebRTC, AWS (S3, EC2), DigitalOcean, Docker, CI/CD, Jest, Playwright, Storybook, and analytics tools like Amplitude. Outside of work, I enjoy building product clones and experimenting with new ideas, constantly sharpening my skills. 📩 pavandeore90@gmail.com
