Building the edge — from Android kernels to Flutter apps, MQTT pipelines to container runtimes. Crafting systems that perform at the boundary of hardware and software.
01 — About
I'm Kesavan G, an Edge Systems & Mobile Developer based in India, with deep expertise in low-latency infrastructure and cross-platform mobile development.
My work spans the full stack of embedded-to-cloud: from building custom Android ROMs and kernels (AOSP), to architecting Flutter applications, to designing efficient Rust-based edge services communicating over MQTT.
I care deeply about systems that are lean, deterministic, and elegant — software that does exactly what it promises at the boundary of hardware and the cloud.

A curated set of tools I use to build resilient, performant systems from the hardware layer up.
