BUILDING WITH INTENTIONSHARING ALONG THE WAY
A FEW CORNERS OF MY WORLD⌘ ajithberlin✳ AlphBerlinஅ BytamilanIndependent ideas. Shared possibilities.

01 / SELECTED WORK

Ideas out in the world.

A few things I’m building,
learning from, and putting out there.

CODE WITH A COMMUNITY IN MIND

Built to be shared.

Through Bytamilan, I explore how open technology can make public information more useful, accessible, and transparent.

02 / LANGUAGE & ENGINEERING CRAFT

Versatile code.
Deep architectural craft.

From low-level memory-safe systems and on-device neural runtimes
to silky 120 FPS native interfaces and modern web platforms.

⚡

Systems to Pixels (Swift + Rust)

Zero-Cost Abstractions at 120 FPS

Bridges memory-safe Rust compute kernels directly with Swift UI layers via C-ABI FFI, crafting silky-smooth creative graphics suites without GC overhead.

🧠

On-Device AI & Speech

Private, Quantized & Cloud-Free

Fine-tunes neural voice models, exports optimized ONNX computational graphs, and deploys offline LLM runtimes directly to mobile devices through Flutter.

🏛️

Civic Impact & Open Goods

Open Data for Communities

Founded Bytamilan to build open civic tools — from waterbody atlases to public transport networks — turning complex civic datasets into transparent interfaces.

04 / THE HUMAN BEHIND THE CODE

Many interests.
One curious mind.

I’m a developer, entrepreneur, and lifelong learner who enjoys making useful things — and making the process a little more playful.

My work moves between full-stack products, creative tools, AI, and open technology. AlphBerlin is where many of those ideas take shape. Bytamilan brings that same curiosity to community-focused projects.
