About

I've spent the last 10 years turning complex product problems into pixel-perfect, high-performance UIs — and I'm ready to do it again, starting immediately. 🚀 What I bring to the table: I'm a Senior Frontend Engineer and former Engineering Manager with deep specialisation in React, TypeScript, and micro-frontend architecture. I've shipped features used by hundreds of thousands of users at companies like Nextiva (a US-based UCaaS leader) and NoBroker (India's largest real-estate platform). Here's what I've done that I'm proud of: → Led and scaled a frontend team from scratch as Engineering Manager at Nextiva's Simplify360 division → Runner-up at Nextiva's Global Hackathon 2024 (Team: Cosmic TrailBlazers) → Recognised under "Honorable Mentions" at Nextiva's Tech All Hands 2025 → Built scalable micro-frontend systems handling complex nested DOM structures and dynamic forms — features my lead described as tackling "the most complex UI challenges with efficiency and creativity" → Drove cross-functional alignment across Product, UX, and QA teams at NoBroker 💡 My technical toolkit: React · TypeScript · Micro-frontends · Redux · Node.js · React Native · HTML5/CSS3 · REST APIs · Jest · Performance Optimisation Beyond the code, I care about mentoring junior engineers, writing clean documentation, and building products people actually enjoy using. I'm an immediate joiner based in Bengaluru, open to senior IC or EM roles at product companies — in India or remote. 📩 If you're hiring or know someone who is, let's talk: DM me here or reach me at kumar93.shashank@gmail.com.
