Senior Frontend Engineer — Mumbai, India

Building scalable web & mobile products for SaaS, IoT and commerce

9+ years shipping production-grade applications with React.js, React Native, TypeScript and Node.js — from workforce intelligence dashboards to BLE/NFC connected device platforms.

01 — About

I design, build and maintain web and mobile applications end-to-end — from the first sketch to the thousandth device in the field.

I work closely with product managers, backend engineers, hardware teams and stakeholders to take products from concept to deployment — and stay with them through the unglamorous parts: performance, data volume, device edge cases and everything real usage throws back.

For the last four years I've been the frontend engineer behind Traceplus, a SaaS workforce management platform for employee tracking, productivity monitoring, attendance automation and location intelligence, and SafeAir, an IoT platform for air quality, occupancy, health monitoring and footfall analytics. Across both I've delivered 10+ production web and mobile applications — real-time location intelligence, indoor 3D visualisation, geofenced attendance, MQTT pipelines and device communication over BLE, NFC and USB, including OTA firmware updates.

I started out in WordPress and WooCommerce, converting PSD and XD designs into responsive sites and growing into custom themes, plugins and business logic in PHP. That's 100+ websites across eCommerce, LMS, fundraising, corporate and directory platforms for clients in the US and UK — including stores with 30,000+ product variations and campaigns generating £10k–£20k+ in orders.
