Work
Ten projects across smart contracts, Telegram bots, on-chain data, Web3 backends and AI platforms. Each case study follows the same shape: the problem, what I built, the stack and the result.
Multi-DEX Swap Router
Solidity contracts that route token swaps through Uniswap V3/V2 and PancakeSwap, built on a diamond (EIP-2535) factory and a transparent-proxy router.
- Solidity
- Hardhat
- TypeScript
0xShield
A Telegram crypto bot to deploy and verify ERC20 tokens from chat, shield groups against spam and bots, and run alerts, lookups, broadcasts and paid packages.
- Python
- web3
- Etherscan API
WebsiteAI Telegram bot
A Telegram bot that builds websites for crypto projects: pick a template, generate copy and images with AI, edit, auto-host and pay in crypto.
- Python
- AI APIs
- web3 / Web3.py
Ethereum Wallet & Token Scraping Tool
A Python/Selenium tool that extracts wallet and token transaction data with filters, historical snapshots and structured CSV exports.
- Python
- Selenium
- CSV
ERC20 Token Holder Analytics Dashboard
A React / Node.js / web3.js dashboard for top holders, balance share, history and wallet behaviour, built to spot accumulation and distribution.
- React
- Node.js
- web3.js
XRP Ledger Trustline Automation Suite
A Python suite that creates, deletes and transfers trustline assets across many XRPL wallets from CSV batches, with validation and safety checks.
- Python
- XRP Ledger
- CSV
Airdrop Scanner
Finds airdrop recipients and amounts from a token deployer’s transactions and filters out contract addresses.
- Python
- Etherscan API
Stuck Transaction Canceller
Cancels stuck EVM / Polygon transactions by replacing them with a same-nonce transaction.
- Python
- web3.py
Alara — enterprise AI platform
Backend architecture for Alara, an enterprise AI platform used by major banks: FastAPI microservices, Kafka/Redis event pipelines and GCP deployments, plus product ownership. Client details are confidential.
- Python
- FastAPI
- Kafka
CNX Network DeFi ecosystem
As CTO, I grew a DeFi ecosystem from 10k to 40k+ users and $400k+ revenue: token contracts, a multi-chain wallet, a token swap service, a launchpad, an authenticator and a chat app, across web and mobile.
- Solidity
- ERC20 / BEP20
- Node.js
Security labs & research code
Public repositories on GitHub, mostly from my MS in Information Security and blockchain research. Small and focused; most of them put a working attack next to its fix.
IDOR & API access-control simulation
Flask API with a vulnerable and a secure endpoint showing Insecure Direct Object References, fixed by binding data access to the authenticated session.
Authentication logic flaws lab
Predictable password-reset tokens: a vulnerable app, a working exploit, and a patched version using secrets.token_urlsafe() and rate limiting.
ECB vs CBC misuse visualizer
Encrypts image pixel data with AES-ECB and AES-CBC to show why ECB leaks plaintext patterns.
Log analysis & SQLi detection
Blue-team script that parses server logs and flags SQL-injection attempts with regex signatures, plus a traffic generator to test it.
Scapy TCP SYN scanner
Hand-crafted SYN packets with Scapy to read the TCP handshake and report open or closed ports.
Trust model for blockchain vehicular energy networks
Research implementation: a revocation-transparency-enabled, data-oriented trust model for blockchain-based vehicular energy networks.
Have a contract, bot or backend to build?
Tell me what you are building. A free 20-minute call is enough to tell whether I am the right engineer for it, and what it would take.
