Manish Aneja — Senior Android Engineer

I build Android interfaces that stay fast and reliable at the scale of 4M orders a day — cart, payments, rendering and the design system underneath them.

Senior engineer at Blinkit (Eternal), where I own cart and payment surfaces, established the Jetpack Compose foundation, and build server-driven UI, observability and release-safety systems used across product teams. I lead a four-engineer Android team and have mentored engineers to promotion.

Cart, payments, rendering, design system & SDUI

Owned the cart surface: lifted conversion 4% (10% for new users) and drove 2% recovery through Save for Later.
Established the Jetpack Compose foundation and standardized 20+ reusable design-system components adopted across product teams — Compose now powers 20% of screens, with new surfaces defaulting to it.
Sped up app launch, cutting cold-start 12% and first-screen render 20% by initializing critical components earlier.
Cut initial load & bind time 3× on a heavy scrollable screen with a virtualized grid that binds in chunks — later reused across Wishlist and other long lists.
Instrumented per-screen scroll metrics now used by other teams, feeding Grafana dashboards and release gates.
Authored incident post-mortems, gated launches with LaunchDarkly, and led sprint planning, code reviews and release delivery for the Android team.

About

I'm an Android engineer who likes building the foundations other engineers build on — rendering, state, design systems and server-driven UI — and then making them measurably fast and safe to ship.

At Blinkit I work where the stakes are highest: cart and payments, the surfaces between a customer deciding and a customer paying. The work spans Compose adoption, virtualized rendering, performance instrumentation, and release gating with real dashboards and post-mortems behind it.

I lead a four-engineer Android team, run sprint planning and reviews, and have mentored engineers to promotion. Outside the day job I write Kotlin, Go and TypeScript, and tinker with side projects.

Let's talk

Building something at scale?

I'm open to senior and staff Android roles where rendering, performance and platform foundations matter. Happy to chat.
