Full-Stack AI Engineer | SaaS Architect | Blockchain & Automation Specialist $100K+ earned | 80+ projects delivered | 5 live products generating active revenue Most developers ship features. I build systems that scale, retain users, and generate revenue after launch. With 10 years of experience operating at CTO level, I have taken products from zero to paying customers for founders across the US, UK, UAE, and Singapore , across AI SaaS, Web3, automation infrastructure, and complex cloud applications. The projects I am most proud of are not the ones that launched. They are the ones still running two years later without a costly rebuild. That outcome starts with architecture decisions made on day one , before a single line of production code is written. Most technical debt, scaling failures, and security incidents are predictable. My job is to make sure they do not happen to your product. Recent work includes: ✅ RYNANCE: AI trading platform analyzing 200K+ influencers in real time, auto-executing trades on Binance, Bybit, and OKX. 4,287 waitlist users. SOC 2 compliant. 99.9% uptime. ✅ Copin: Copy-trading platform with 105,800+ trades completed in production. ✅ Baby-Sol : Served as CTO. Crossed $100M market cap in 4 weeks. Certik audited at 95%. ✅ Temoc: Web3 content distribution platform. Raised $720K. CTO and Tech Lead. Core expertise: AI & Agentic Systems — OpenAI, Claude, RAG, Voice AI, LangChain, n8n Full-Stack SaaS — React, Next.js, Node.js, Python, PostgreSQL, Supabase Blockchain & Web3 — Solidity, DeFi, NFT platforms, tokenomics design Cloud & Infrastructure — AWS, Azure, GCP, Docker, Kubernetes, CI/CD If you're looking for a technical partner who understands both engineering and product strategy, I'd be happy to discuss your project.

Most blockchain projects don't fail on the idea. They fail on an unchecked account, a missing signer validation, or math that overflows the first time real volume hits, and when there's a DEX, a treasury, or a live token on the line, that's not a bug, it's a loss. Making sure that never happens is the core of what I do. I'm a senior blockchain engineer focused on Solana and other blockchains, with production work across DeFi infrastructure, NFT platforms, and smart contracts. I've spent the last 6+ building systems that handle real value and hold up under real load - $5B+ Value Routed, 1M+ Users, 99% Uptime, 850M+ TVL. Some of the work I've been part of : • Carbium - full-stack Solana infrastructure: a DEX aggregator, high-performance RPC, and a validator. Rust-heavy work on gasless swaps (trade without holding SOL), MEV-aware routing, and Yellowstone gRPC full-block streaming (~22ms), exposed through clean SDKs in Rust, TypeScript, and Python. • CertDigital - a platform for issuing and verifying blockchain-secured credentials as compressed NFTs (cNFTs) on Solana: certificates and badges that stay verifiable for life. • SoSH - a Web3 social platform and NFT marketplace (Ethereum) where users mint their social posts as NFTs and earn ongoing royalties on every resale, with wallet integration, KYC, referral rewards, and marketplace search. The stack I live in: Rust, Anchor, the Solana Program Library (SPL), including Token-2022, Metaplex and compressed NFTs, @solana/web3.js, plus Solidity/EVM when a project needs it. Testing with Anchor tests, LiteSVM, and Bankrun across localnet, devnet, and mainnet. How I work: updates in plain language, not walls of jargon. I'll tell you a feature needs two more days before I'll hand you something I wouldn't trust with my own funds. Everything ships tested, and every audit I write can be understood by a non-technical founder and acted on by a dev. If you're building on Solana or other blockchains and real value is on the line, a DEX, a token, an NFT drop, a credential system, or you want a serious second opinion before you launch, send me a note. A rough description is plenty. I'll tell you honestly whether I'm the right fit and how I'd tackle it.
