What I'm looking for

I’m looking to build fast, secure, production-grade web products with React/Next and extend them with generative AI and agentic workflows. I want an agile team where I can ship user-focused features, improve performance, and automate smarter workflows.

I’m a Senior Frontend Developer with 6.5+ years building high-performance, scalable web and mobile applications using React.js, Next.js, and React Native. I’ve shipped secure, production-grade platforms across fintech and proptech, including an end-to-end ISO internal web platform that automated loan processing, cutting load times by 40% and improving operational efficiency.

I focus on reusable, scalable UI systems—like establishing a component library from Figma designs—to speed delivery and improve consistency. Now, I’m extending frontend expertise into generative AI, agentic workflows, and automation using tools like n8n, ChatGPT, Claude, and Groq to build intelligent, AI-augmented products.
