About

I’m a Full Stack Engineer with strong expertise in modern frontend engineering, AI/agentic workflows, and scalable product architecture. I’ve built products from 0→1 in high-velocity startup environments and contributed to large-scale systems in enterprise teams. Currently, I’m a Founding Engineer at Gigin.ai, where I’m leading the end-to-end development of an AI-powered ATS and recruitment automation platform. I architected the entire product from scratch using React, Next.js, TypeScript, and an Nx monorepo, improving performance by 15% across web and mobile. I also built an AI agent orchestration system using LangChain, LangGraph, RAG pipelines, vector databases, and Elasticsearch—enabling intelligent candidate matching and automated recruitment workflows. Before this, I worked as a Senior Frontend Engineer at CAI Platforms, driving a full UI migration to React, building a company-wide design system with 80+ reusable components, and setting up a monorepo architecture with Microsoft Rush. My work reduced render times by 47%, bundle size by 90%, and improved developer efficiency for a multi-tenant MLOps SaaS platform. My earlier experience at Optum (UHG), Arista Networks, and Samsung R&D gave me a strong foundation in full-stack engineering, system testing, and network tooling. I love building clean, scalable, predictable systems—whether it’s modern frontends, AI agent pipelines, or microfrontend architectures. I enjoy mentoring teams, shaping engineering best practices, and turning product ideas into reliable, user-first experiences. If you're working on AI, SaaS, developer tools, productivity, or B2B products, I’d love to connect.
