Senior Engineering Manager at New Engen & independent developer at WhoIsRishav.com — building scalable products across Full Stack, Mobile & Web3.
About Me
I'm Rishav Kumar — an Engineering Leader based in India with hands-on experience across Full Stack, Mobile, and Web 3.0 development. At New Engen, I lead engineering teams to ship high-impact, data-driven products at scale.
Beyond my day job, I run WhoIsRishav.com — a freelance practice where I build bespoke digital products for clients worldwide, specializing in cross-platform mobile apps with Flutter and modern web applications.
I'm passionate about knowledge sharing and run a YouTube channel where I publish tutorials on programming, Flutter development, and the broader tech ecosystem.
Career
A journey through the roles and companies that have shaped my engineering leadership and technical depth.
Leading cross-functional engineering teams to build and scale data-driven digital marketing and analytics platforms. Responsible for technical strategy, team growth, architecture decisions, and delivery excellence across multiple product lines.
Building bespoke digital products for clients globally — from cross-platform Flutter mobile apps to full-stack web platforms and blockchain integrations. Key projects include LIFT by LT Partners (Partnership Analytics SaaS) and AUTOLOOP Tags (IoT vehicle notification system).
Progressed through individual contributor roles, building expertise in full-stack development, mobile engineering with Flutter/Dart, and early-stage Web3 development. Contributed to production systems serving millions of users.

A curated toolkit built over years of shipping production software across mobile, web, and blockchain domains.
Portfolio
Handpicked work spanning SaaS platforms, mobile apps, and experimental Web3 products.
