VONSSY.

Vonssy / Reyvaldi Zakaria

Web3 Builder · Automation Engineer · Software Developer

Software
that does
things.

I build automation systems, bots, and software that interact with real APIs, wallets, blockchains, and data.

From fundamentals to automation.

Vonssy is the builder identity of Reyvaldi Zakaria. The work started broad: programming fundamentals, C and C++, JavaScript, PHP, SQL, Python, AI and machine learning, and mobile development.

That path moved through web applications and backend systems into software that runs against the real world: wallets, blockchains, external APIs, accounts, proxies, and data. The point is not collecting technologies. It is combining enough of them to make a working system.

learning → experimenting → building → automating

How I build

The recurring decisions behind the repositories, not a manifesto.

Build for reality

Software should meet real APIs, networks, wallets, services, and failure conditions.

Automate the boring parts

Repeated workflows become useful when they can run predictably without supervision.

Reliability matters

Retries, rate limits, proxies, state, concurrency, and recovery deserve deliberate handling.

Keep it practical

Prefer understandable systems over abstractions that make the work harder to operate.

Selected work

A focused selection from two public GitHub accounts. Every description is tied to repository metadata or documentation.
