Meet Mitesh
An AI-first Senior Frontend Engineer who turns ideas into lightning-fast, scalable digital products. I've built 40+ web apps across FinTech, EdTech, e-commerce, and healthcare for international clients, always with a focus on speed, design, and usability.
Opening Hook
I'm Mitesh Tagadiya, an AI-first Senior Frontend Engineer specializing in React.js, Next.js, and TypeScript. Over 8+ years I've delivered 40+ high-performance web apps for clients in the US, UK, Canada, South Korea, and the Middle East, converting Figma designs into scalable component systems, integrating global payment gateways, and shipping LLM-powered chatbots and AI agents with OpenAI, Claude, and the Vercel AI SDK.
Professional Journey
My journey began in 2018 at DataOne Innovation Labs, a 15-person startup, where I shipped production React.js UI, architected a config-driven FinTech banking platform with micro-frontends, and mentored interns and junior engineers.
From 2021 to 2022 at Pansuriya Infotech, I built React.js and Next.js apps for international clients with direct stakeholder communication, integrating payment gateways, real-time video and whiteboard features, and CI/CD pipelines.
Since 2023 I work independently as a freelance Senior Frontend Engineer, owning end-to-end frontend delivery across FinTech, EdTech, e-commerce, and healthcare, and shipping AI-powered features with OpenAI, Claude, and the Vercel AI SDK.
Problems I Solve for Clients
As a senior frontend engineer, senior React / Next.js developer, and frontend architect, I help startups, SaaS, FinTech, and agencies when:
- Legacy Vue/React apps are slow — I migrate to Next.js and cut load times from minutes to seconds.
- Checkout conversion leaks — I integrate Stripe, PayPal, Kakaopay, and Naver Pay with cleaner flows.
- Product needs AI — I ship chatbots, agents, and semantic search with OpenAI, Claude, and the Vercel AI SDK.
- Teams need scale — I architect micro-frontends and config-driven UI so non-engineers ship screens faster.
Personal Touch
When I'm not building frontends, you'll find me exploring new coffee spots, tinkering with side projects, or reading about UI/UX psychology. I believe in continuous learning and sharing knowledge with the community.
