𝐄𝐱𝐩𝐞𝐫𝐭-𝐕𝐞𝐭𝐭𝐞𝐝 (top 1% on Upwork) and 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬, with $𝟒𝟎𝟎𝐊+ earned across 𝟏𝟐𝟓+ projects. I'm a founder and full-stack engineer who acts as your technical partner, architecting AI and blockchain systems that work in production, not just in a demo. Most clients come to me when the build actually matters: when it has to be secure, has to scale, and has to handle real data or real money without breaking. I architect and build custom systems end to end, and I can bring in a vetted team when a project needs more hands. Think of me as a fractional CTO and a builder in one: senior judgment on the strategy, real hands on the code. A lot of AI talent stops at a clever prompt and a slick demo. I come at it as a systems engineer. I have architected a Layer 1 blockchain hardened with post-quantum cryptography, a decentralized exchange and validator platform, an on-chain tokenization system for commercial real estate, and production AI agents that run real sales and operations workflows. I work natively in fintech and regulated systems, so I'm as fluent in tokenomics, compliance, and data-heavy infrastructure as I am in the code itself. If your AI or your protocol has to be correct, not just impressive, that is the gap I fill. 𝐖𝐇𝐀𝐓 𝐈 𝐁𝐔𝐈𝐋𝐃 • AI agents and automation: multi-agent systems, LLM integration, RAG, and automation wired into your real tools and data • Custom full-stack software: React / Next.js, Node.js, Go, Rust, and databases, built and shipped end to end • Smart contracts and protocols (EVM and Solana): audited, gas-optimized, production-ready • DeFi and tokenization: staking, swaps, liquidity, governance, and real-world-asset / on-chain systems • AI for fintech and on-chain: the rare overlap of AI, blockchain, and financial systems, done by one person who understands all three • Technical strategy: architecture, security review, tokenomics, and the roadmap to get there 𝐖𝐇𝐘 𝐂𝐋𝐈𝐄𝐍𝐓𝐒 𝐇𝐈𝐑𝐄 𝐌𝐄 • 𝐄𝐱𝐩𝐞𝐫𝐭-𝐕𝐞𝐭𝐭𝐞𝐝 and 𝐓𝐨𝐩 𝐑𝐚𝐭𝐞𝐝 𝐏𝐥𝐮𝐬: roughly the top 1% of Upwork talent, with $𝟒𝟎𝟎𝐊+ earned and 𝟏𝟐𝟓+ projects delivered • A founder's perspective: senior judgment on strategy, with real hands on the code • Security and correctness first: audits, hardening, and systems trusted to move real value • Senior, direct communication and predictable, on-time delivery If you are building an AI product or a custom platform, automating real operations, launching a protocol, or tokenizing real-world assets, and you want a technical partner who will get it right the first time, let's talk.

I hold Upwork’s Expert-Vetted badge, placing me among the top 1% of blockchain engineers on the platform, recognized for deep technical expertise, reliability, and consistent delivery. I am a senior Blockchain Engineer with 6+ years of hands-on experience designing and delivering production-grade smart contracts, DeFi protocols, token launch infrastructure, and staking systems across Ethereum, BSC, Solana, TRON, and EVM-compatible chains. I specialize in: - Token launch & fundraising contracts (presale logic, vesting, allocations) - Staking & rewards systems (APR logic, emissions, compounding) - DeFi protocols (lending, liquidity, yield mechanisms) - Secure, gas-optimized Solidity smart contracts - Smart contract integrations with existing platforms and backends I’ve contributed to 300+ blockchain projects, including live exchanges and large-scale on-chain systems, giving me a full lifecycle understanding — from protocol design and architecture to deployment, testing, and post-launch support. Security, scalability, and long-term maintainability are always first-class concerns in my work. While I have experience with NFTs, my current focus is on real utility blockchain systems — DeFi, staking, token economics, and secure on-chain infrastructure that supports sustainable products. ⭐ 99%+ of my client reviews are 5-star, reflecting clear communication, on-time delivery, and dependable execution. If you’re looking for a senior blockchain engineer who can take ownership of complex smart contract systems and deliver with confidence, I’d be happy to discuss your project and help you move forward efficiently.

I work with startups and businesses to build blockchain products, AI-powered systems, and scalable web applications that are designed for real users ........... not just technical demos. Over the last 8+ years, I’ve helped clients develop everything from DeFi platforms and crypto wallets to automation systems, AI integrations, and full-scale SaaS products. My focus is always on building products that are secure, practical, and ready to grow. I enjoy working closely with founders and teams who care about creating solid long-term products, whether that means launching a new Web3 platform, improving an existing application, or integrating AI into business workflows. Areas I Commonly Work On Blockchain & Smart Contract Development Web3 Applications AI Agents & Workflow Automation DeFi & Crypto Platforms NFT & Tokenization Projects Full-Stack SaaS Development API & Backend Architecture Product Scaling & Optimization Tech Stack Blockchain: Solidity, Ethereum, Solana, Rust, Hyperledger, Web3.js, Ethers.js Frontend: React.js, Next.js, TypeScript, TailwindCSS Backend: Node.js, NestJS, Python, Go, REST APIs What You Can Expect Working With Me Clear communication Reliable delivery timelines Clean, maintainable code Attention to performance and scalability A practical approach focused on business goals I prefer building long-term working relationships and contributing to projects where thoughtful engineering and product quality actually matter.

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.
