Why I'm Writing Here Now

I'm Evgeny. I write backend systems that turn messy raw data into something people can actually query, trust, and build on. For the last six years that's mostly meant blockchains — indexers, ETL pipelines, SDKs, APIs that sit between "the chain emitted an event" and "the product shows the right number."

How I got here

I didn't set out to be a blockchain engineer. I ended up there the way most good careers happen — by solving one hard, specific problem well enough that it led to the next one. At DexGuru, that problem was ingesting on-chain events across multiple EVM chains fast enough and cleanly enough that a trading product could rely on it. At SQD, it was building the client library that lets anyone stream indexed on-chain data straight into a Python pipeline without fighting the plumbing.

What I actually like is the shape of the problem, not the buzzword. Raw data is chaotic. Someone has to design the schema, own the caching, decide what "correct" means when three sources disagree, and make the whole thing fast enough that nobody downstream has to think about it. That's the job, whether the data is on-chain events, health records, or log lines.

What I'm doing now

I'm based in Belgrade, working on backend and data systems — these days that increasingly means LLMs and retrieval, not just pipelines. The underlying skill transfers directly: same instinct for schema design, same obsession with making retrieval fast and answers trustworthy, just pointed at a different kind of raw material. I've also been building things on the side — small products, not just infrastructure for other people's products. More on those as they're ready to talk about.

What's next

This blog is where I'll write about the stuff that doesn't fit in a commit message: decisions I made and would make differently, tradeoffs in data pipeline design, what building small products on the side teaches you that a day job doesn't. If you're building something similar, or you have a data problem that's currently held together with duct tape, I'd like to hear about it.

More soon.
