01 / Case study
The challenge
Trading systems must coordinate market data, analysis, exchange or broker APIs and multiple account states. Blockchain projects add different network rules, connection methods and transaction lifecycles. The challenge is turning these components into usable workflows, from order execution and tracking to contract interactions, cross-chain transfers and customer payment recognition. This page covers several independent projects, each developed for its own product requirements.
My contribution
Developed Python market analysis algorithms and connected trading and copy trading software to exchange APIs and MetaTrader. Blockchain work includes Bitcoin RPC, smart contracts on Ethereum forks and Tron, anti-bot logic, centralized and decentralized exchanges, bridges and custom crypto payment gateways. Further experience includes NFT creation and marketplaces, NFT-based games and new blockchain products, connecting contract logic and network services to backend systems and user interfaces.
Analysis & execution
Price action analysis
Used data from sources including MetaTrader and TradingView. Python algorithms identify uptrends, downtrends, momentum, sideways markets and pullbacks, focusing on price behavior.
Financial service integrations
Experience with Binance, CoinEx, KuCoin, MetaTrader, IG and broker APIs for opening and closing positions, order management and simultaneous multi-account execution.
Copy trading
Built Windows software for Binance copy trading and a separate MetaTrader system for replicating trades across accounts and brokers.
Network infrastructure & Bitcoin RPC
Direct network integration supports transaction processing and custom blockchain services.
Bitcoin RPC development
Developed software integrations with Bitcoin nodes through RPC to read network and transaction information and connect node capabilities to application logic. This layer makes chain data available to custom services.
Multiple network integrations
Worked with Ethereum, Binance Smart Chain, Cronos, Ethereum forks and EVM-compatible networks, as well as Tron, accounting for their different connection methods, contracts and transaction processing.
Smart contracts & anti-bot logic
Product rules are implemented in contracts and exposed through services and user interfaces.
Contracts on Ethereum forks & Tron
Designed and implemented smart contracts on Ethereum forks, EVM-compatible networks and Tron for tokens and custom blockchain product logic, using the appropriate structure and tools for each network.
Anti-bot implementation
Developed anti-bot rules in smart contracts to control unwanted automated behavior in product workflows. Restrictions and their activation conditions are defined according to each project's requirements.
Connecting contracts to products
Developed DApps and connected contracts to backend services and interfaces, from reading data and requesting transactions to displaying operation status. Experience also includes initial token sales.
Centralized & decentralized exchanges
Centralized exchange integrations
Integrated APIs from exchanges including Binance, CoinEx and KuCoin for market data, order submission and management and account-state tracking in trading and copy trading software.
DEX, swaps & liquidity
Developed a decentralized exchange for a Canadian client, including token swaps and liquidity pools, connecting contract logic to the product's user experience.
Bridges & custom crypto payment gateways
Asset transfers and payment collection connect chain information to application workflows.
Bridge implementation
Developed bridge solutions for connecting networks and transferring assets, linking source and destination network operations to product workflows and tracking transfer status in the application.
Custom crypto payment gateways
Implemented cryptocurrency payment gateways for business requirements, connecting to networks, recognizing payment transactions and linking their results to orders or user accounts within the product.
NFTs, marketplaces & blockchain products
NFT creation & marketplaces
Implemented NFTs and their marketplaces, connecting ownership and contract operations to asset displays and purchase and sale workflows for the chosen use case and network.
NFT-based games
Built 2D JavaScript games with NFT characters, including in-game minting, purchases and sales, connecting blockchain assets to the gaming experience.
New blockchain systems
Designed and implemented custom products combining smart contracts, backend services and interfaces, turning business requirements into usable workflows involving on-chain data, assets and transactions.
