Hi. I'm Dmytro! I write
developer docs for
web3 and AI companies.

5 clients · Fintech, L2s, Stablecoins

Technical writer with 8+ years of experience in APIs, blockchain ecosystems, and AI workflows. I turn complex systems into documentation developers use.

Dmytro worked with us at OMG Network as a technical writer. He took our developer portal and reworked how we maintained it, so the documentation actually kept pace with how fast the product was evolving. He also put together sample code and small demo apps that helped partners integrate on their own. I remember the Bitfinex team going through the integration without any major questions for us, which says a lot about how clear the docs were. He also did a lot of the work on the spec for our Community Points Engine, which we submitted as part of Reddit's scaling competition. He wasn't the lead on that project, but he pulled a lot of it together and made sure it actually read well and made sense to people outside our team. Dmytro is easy to work with, reliable, and just gets things done without needing a lot of hand-holding. Great person to have on a team.

Kasima Tharnpipitchai

Chief Technology Officer, OMG Network

Dmytro is an excellent communicator and documentation expert. His technical depth and expertise ensure that documentation he owns are technically correct and well-informed with code samples, taking on the heart of developer documentation. Combining this with his empathy means that he's an asset to any DevRel / API team.

Stephen Fluin

Head of Developer Relations, Chainlink

Dmytro is a strong technical writer, developer relations and an all rounded software specialist that can wear multiple different hats. He is not afraid to jump in with high ownership and get a good grasp of difficult technical domain. His high bar for technical writing quality, obsession with good developer experience and ability to work autonomously can be a force multiplier that gives your software product a polish required for good integrations experience.

Pong Cheecharern

Technical Product Manager, OMG Network

I had the pleasure of working with Dmytro during our time at Myria, where we built our SDK ecosystem and developer experience from the ground up. D consistently demonstrated strong technical curiosity, deep research skills, and an excellent ability to translate complex technical concepts into clear and practical documentation. He didn't just document feature, he invested time in understanding the underlying architecture, developer workflows, and potential challenges that users might face. His contributions to our SDK documentation, technical guides, and sample implementations played a significant role in helping developers onboard quickly and successfully integrate with core platform. Beyond his technical writing expertise, he regularly brought valuable insights and thoughtful suggestions that improved both the developer experience and the overall quality of our technical resources. I would highly recommend D to any team looking for a technical writer who can effectively bridge the gap between engineering and developers while maintaining a strong technical foundation.

Documentation built for both humans and agents

Every sample in my portfolio includes working code, verified output, and context explaining the decisions behind it.

Each piece is clear enough for a developer reading through it, and structured for AI agents to consume directly.

  ProjectResponse
} from "myria-core-sdk";
import config from "../config";

(async (): Promise<void> => {
  const starkKey: string = config.stark_key;
  const env = config.environment;

  const projectManager: ProjectManager = new ProjectManager(env);
  const projectId: number = config.project_id;

  const params: UpdateProjectParams = {

  const updatedProjectResponse: ProjectResponse = await projectManager.updateProject(params);

  console.log("Updated project response:");
  console.log(JSON.stringify(updatedProjectResponse, null, 2));
})();

CLIs & Sample Apps

Runnable code. I build minimal working apps so the reader can clone, run, and adapt rather than guess from incomplete snippets.

This Chainlink has a dedicated connection to [FlightAware](https://uk.flightaware.com/).

### Steps for using this oracle

1.  **Write and deploy** your Chainlink contract using the network details provided.
2.  **Fund** the contract with [LINK](https://docs.chain.link/resources/link-token-contracts).
3.  **Call** your request method.

Basic Contract Structure (Solidity 0.6.0):

```solidity
pragma solidity ^0.6.0; 

import "@chainlink/contracts/src/v0.6/ChainlinkClient.sol"; 

contract FlightAwareChainlink is ChainlinkClient {
  uint256 oraclePayment;

  constructor(uint256 _oraclePayment) public {     
      setPublicChainlinkToken();     
      oraclePayment = _oraclePayment;   
  }   
  // Additional functions here...
}
```

Case Studies

L2 Infrastructure · Docs-as-code · Samples App · Product Spec

OMG Network

Integration time: 2 hours → 3 minutes

OMG Network's Plasma-chain docs couldn't keep pace with an actively shipping protocol and partners had no single path through an integration. I rebuilt the Docusaurus portal on a docs-as-code workflow, built a JavaScript samples app covering every omg-js operation, wrote end-to-end use-case guides for exchanges and wallets (cutting integration time 60-70%), and authored the Community Points Engine technical specification, which received the highest ranking in Reddit's Great Scaling Bake-Off.

Developer Portal · Guides & Tutorials · Community

Chainlink

Support volume down 30–40%

Chainlink's portal was a closed Read the Docs site with no path for community contributions. I helped migrate it to an open-source Eleventy site, then shipped integration guides for every new data feed and automation feature as they landed: price and data feeds, L2 sequencer health, job requests, and Automation upkeep. I also embedded in hackathons and Discord to feed developer friction back into the docs rather than answering the same questions one at a time.

SDK References · Sample App · Developer Portal

Myria

Partner integration time dropped 70–80%

Myria had no public developer documentation when I joined. Partners depended entirely on direct access to the engineering team. I built the portal from scratch, including SDK references, a Stark key SDK helper, a TypeScript samples app with runnable examples for every core flow, and a quickstart for new partners. Within weeks of launch, high-profile partners including AB de Villiers and LeapBlock Studios had integrated.

Content Strategy · API Docs · POS Integrations

Paytomat

Audience engagement up 35–45% in the first few weeks

Paytomat built crypto POS infrastructure for merchants and needed to build an audience around it while simultaneously managing API docs for live integrations with NCR, Poster, and 1C. I ran the content strategy that grew engagement, contributed to two whitepapers that opened doors with non-technical clients (increasing interest by 30–40%), and kept the Console Panel REST API documentation accurate across three concurrent partner integrations. I also represented Paytomat at Malaysia's MaGIC Accelerator Program.

Toolchain

Docs-as-code, all the way down.

Every doc I produce lives in version control, ships through CI, and is reviewed like code. Documentation stays in sync with the product.

See examples

Platforms I work with

From static generators to hosted portals. I pick the right tool for your stack and constraints.

Git & GitHub

Docs-as-code version control and PR reviews.

MDX / Markdown

Rich content authoring with component embedding.

OpenAPI / Swagger

Spec-first API documentation and validation.

Docusaurus

Static doc sites for open-source and developer portals.

Mintlify

Modern hosted docs for API-first products.

Fumadocs

Next.js-native documentation framework.

QA-like mindset

Every API endpoint, CLI command, and code sample gets tested against a working environment before it appears in the docs. If it doesn't run, it doesn't ship.

createWallet.ts


export async function createWallet(opts: CreateWalletOptions): Promise<void> {
  const network = resolveNetwork(opts.network);

  const words    = await mnemonicNew(24);
  const mnemonic = words.join(' ');
  const keyPair  = await mnemonicToPrivateKey(words);
  const wallet = WalletContractV5R1.create({
    workchain: 0,
    publicKey: keyPair.publicKey,
    walletId: { networkGlobalId: config.networks[network].globalId },
  });

  const address    = formatAddress(wallet.address, network);
  const bounceable = formatAddressBounceable(wallet.address, network);

  console.log('New TON wallet created');
}
