Profile
Who I am, how I work, and what I bring to a product team.
Frontend engineer
I'm Yash Kapure, a frontend engineer with 4+ years of experience. I ship UIs and full-stack features with React, Next.js, Angular.js and TypeScript for product companies and startups in the US, UK, EU, and India. Based in the UK, I work remotely.
Alongside my frontend experience, I possess good full-stack skills in JavaScript and TypeScript, and familiar experience in Node.js, Express, and databases like MongoDB and MySQL. This allows me to manage projects from start-to-finish, from designing smooth UIs through connecting scalable backends.
“I have built software for product companies, clinics, and start-ups, delivering maximum performance, engagement, and lead capture through precise engineering. Writing elegant, up-to-date code and discovering new tools and trends thrills me.”
Outside of work, I enjoy cricket and a good cup of tea, but now I am used to drinking coffee. I'm always up for learning, experimenting, and growing and looking for opportunities wherein I can bring value toward impactful products and inventive teams.
React, Next.js, and TypeScript UIs for real traffic, clear ownership, and long-term change.
APIs, auth, data, and UI glue so features ship end to end without handoff gaps.
UK-based. Comfortable with US, UK, EU, and India teams across async and overlap hours.
Performance, accessibility, and UX detail treated as product work, not extras.

Case studies
Two builds I owned end to end, from the hard calls to production.
Full-stack product
A full-stack booking platform where customers discover wellness venues, reserve slots, and pay online - while owners manage bookings, availability, and refunds from one portal.
Designed and shipped end to end, solo, into production at calmllama.life: self-serve booking, payment-first checkout (Stripe + Apple Pay), and a single owner portal for bookings, availability, and refunds.
Real-time full-stack
A browser-based technical-interview platform: live video, a collaborative code editor that runs 13 languages, chat, scheduling, and QR-based candidate join - all in one room.
Built solo, end to end - one room that replaces a video call, a shared coding pad, and a scheduling thread. Three real-time transports (WebRTC, WebSockets, REST) coordinated so media stays peer-to-peer and the server is a matchmaker, not a bottleneck.
