I am Mehdi Khosa, a software engineer focused on building fast, practical, production-style systems across full-stack web, blockchain, AI automation, and trading products.
I work where software needs to be more than a UI: smart contracts, wallet flows, Telegram bots, crypto signal engines, trading alerts, reward systems, NFT marketplaces, bridges, automation pipelines, and backends that keep the product moving.
Core lane: Full-stack engineering + blockchain systems
Strong edge: Crypto, Forex, trading bots, Telegram automation, AI workflows
Web3 depth: EVM, Solana, TON, SUI, DeFi, NFTs, marketplaces, token systems
Mindset: Ship fast, keep systems clean, make the product feel premium|
Smart contracts, dApps, staking systems, token minters, NFT collections, marketplaces, DeFi flows, wallet UX, and blockchain explorers. |
Crypto signals, Forex/EA-style automation, market alerts, Telegram bots, rule engines, arbitrage workflows, and real-time notification systems. |
|
Next.js and React frontends, Node/Nest/Express APIs, PostgreSQL/MongoDB data layers, dashboards, admin tools, and production deployments. |
AI-assisted engineering, automation-first backend workflows, intelligent tooling, product accelerators, and systems that reduce manual work. |
| Project | What It Shows | Stack / Domain |
|---|---|---|
| Crypto Signals | Real-time crypto signal platform with Telegram delivery | Next.js, Node.js, PostgreSQL, Telegram Bot |
| Trading Alerts | Indicator-driven crypto trading alerts and notifications | Next.js, Node.js, PostgreSQL, TradingView-style rules |
| BCoinBets | Bitcoin prediction and betting product | MERN, Solidity, Hardhat, Polygon |
| KatanaInu Reward System | On-chain game reward distribution engine | Ethereum, Thirdweb, NATS, Node.js, MongoDB |
| SUI NFT Marketplace | NFT minting, trading, and marketplace mechanics on SUI | SUI, NFTs, bulk minting |
| Solana Token Minter | Production-style SPL token minting UX | Solana, Anchor, Rust, Next.js, TypeScript |
| TON Jetton Token | CLI-driven Jetton deployment and minting | TON, wallets, smart contracts |
| PeoplesDex | DEX built from internship work into a real Web3 product | Next.js, Solidity, Hardhat, Ethers.js |
| Custom Blockchain | Proof-of-Work blockchain and node simulation | Node.js, Express, JavaScript |
Some client and production work is private, but the patterns are visible here: secure contracts, fast frontends, reliable backends, automation, and business-focused delivery.
1. Building trading platforms, signals, alerts, Telegram bots, and automation products.
2. Shipping blockchain systems across EVM, Solana, TON, and SUI.
3. Designing fast, modern, recruiter-ready and product-grade frontends.
4. Writing backend services that are clean, observable, and easy to scale.
5. Using AI as an engineering accelerator, not a replacement for engineering judgment.| Primary role | Full-Stack Software Engineer, Blockchain Engineer |
| Product domains | Crypto, Forex, DeFi, NFTs, trading systems, bots, AI automation |
| Best fit | Teams that need someone who can connect product, frontend, backend, contracts, and delivery |
| Open to | Strong engineering teams, Web3 products, trading platforms, automation-heavy products, and serious freelance work |
