Projects

Backend systems, trading bots, and automation I've designed and shipped — sorted newest first.

PHINIX — Low-Latency Trading Engine↗

2025
Trading infra · designed & built solo

A low-latency Solana trading bot I designed and shipped end-to-end. It streams market data over gRPC from dedicated nodes, caches hot state in Redis, and executes sniping, copy-trading and real-time PnL with customizable Jito fee strategies — engineered to land transactions before the rest of the market.

Freelance Automation — Bots & Trading Strategies

2025
Freelance · dozens of clients

Across dozens of freelance engagements I automate the slow, boring, manual work clients don't want to touch — and build the profitable kind: copy-trading, sniping, and custom strategies that run themselves on dedicated Solana nodes I provision and tune on Linux. Each one is a small, reliable backend that just keeps running.

Chainge Finance — Multi-Chain Swap Bot↗

2024
Automation · backend lead

A Telegram trading bot spanning five networks for Chainge Finance, a leader in cross-chain swaps. NestJS backend with Ethers.js and Solana Web3: routes swaps through KyberSwap and Jupiter, handles wallet creation, deposits, cross-chain bridging, sniping and a gem finder — backed by Helius and Moralis nodes for reliable, low-latency reads.

Multi-Chain Wallet Service @ Kayros

2024
Kayros · backend infra . Project Manager

The backend wallet service behind Kayros's play-to-earn gaming platform — a single typed interface for key management, signing, and transfers across 20+ EVM networks. Built so the game and marketplace could support multi-chain custody without rebuilding it per network. Served 9,000+ users.

NFTICKS — NFT Ticketing Platform

2023
Product · founder

My own product: a backend and smart-contract platform for minting NFT tickets that gate access to communities (Discord, Telegram). NestJS services power the marketplace — buy, sell, and rent — on top of Solidity contracts, with a decentralized, community-driven access model.

Blockchain Engineering Suite↗

2021
Early work

A suite of projects building the foundations I now apply to backend systems: an NFT marketplace, a play-to-earn game (ERC-721), and an advanced ERC-1155 project — each pairing Solidity contracts with React and Hardhat tooling.
