Hire the Best MoonScript Specialists

I am a Senior Blockchain Developer and Technical Lead with 8+ years of experience building secure, scalable, and production-ready blockchain products across Solana, Ethereum, BSC, Polygon, and EVM-compatible chains. I help startups, agencies, and product teams design, build, audit, and launch Web3 products, from MVP to production. My core expertise includes: Smart Contract Development Solidity, Rust, Anchor Framework, Hardhat, Foundry, OpenZeppelin, ERC20, ERC721, ERC1155, SPL Token, staking contracts, vesting contracts, presale contracts, airdrop systems, NFT smart contracts, and token launch systems. DeFi & DEX Development DEX integrations, AMM systems, liquidity pools, staking platforms, yield farming, Uniswap, PancakeSwap, Raydium, Jupiter Aggregator, Chainlink Oracle integrations, and DeFi dashboards. Solana Development Rust smart contracts, Anchor programs, SPL tokens, Solana NFT systems, Raydium integration, Jupiter integration, Solana trading bots, and wallet-based dApps. Web3 Frontend & Wallet Integration MetaMask, WalletConnect, Phantom Wallet, Web3.js, Ethers.js, Viem, Wagmi, React.js, Next.js, and blockchain API integrations. Bots & Automation Crypto trading bots, DEX trading bots, Telegram crypto bots, arbitrage bots, market-making bots, token sniper bots, wallet monitoring, and market data WebSocket systems. As a Technical Lead, I also help with blockchain architecture, code reviews, smart contract security, gas optimization, team coordination, deployment planning, and production support. I focus on clean architecture, secure contracts, clear communication, and delivery that matches real business goals, not just writing code.

I build web apps that touch real money and real users: Stripe billing with webhooks that can't double-fire, Supabase Postgres locked down with row-level security, Next.js App Router in production. 8+ years, 80 Upwork jobs, 100% JSS, Top Rated. Most of my work lands in one of these lanes: Payments - Stripe Billing, Checkout, Customer Portal, Connect. Production experience, including the unglamorous parts like idempotency and reconciliation. Full-stack builds - React / Next.js / TypeScript up front, Node.js / NestJS or Python behind, PostgreSQL / Supabase / MySQL underneath. Auth that works - Keycloak, OpenID Connect, NextAuth. Once fixed a broken production SSO nobody could touch for months; took 9 days. Shopify - checkout extensions and Shopify Functions, including a volume-discount engine written in Rust/WASM. Three public repos on my GitHub. Web3 - Solana and EVM, Rust, three years of it. Some numbers instead of adjectives: cut a fintech dashboard's heaviest route JS by 65%, shipped a 315-user internal portal to production in two weeks, my content sites score 98-100 on PageSpeed. I work async and in writing, with concrete updates - you always know where things stand. I use AI tooling heavily and openly, and I review every line before it ships. Speed without the slop. If it involves payments, auth, dashboards, Shopify checkout logic, or a Next.js build that has to actually ship, send it over and I'll tell you straight what it takes.

I’m a Software/AI & VPS Engineer, I can fix anything with zero mistakes n build everythings easily n fastest, i got unlimited Codex token, love to do things OpenClaw, Blockchain, Pipeline, flutter, flutterflow, build tools, Internal tools, Modules, Bot, PineScript, Mod, sys Linux n i can copy any site 100% match quick n easy n i strong in backend and full-stack systems and build Web apps, Mobile Apps, Desktop Apps, Rust/Tauri, Electron, Browser Extension n trading system, n strong Web3 edge (EVM, Stellar & Solana). I turn ambiguous ideas into secure, reliable, human-centered products using TypeScript/JavaScript, React/Next.js, Node.js/Nest, Go, Python, Solidity, Rust (Anchor), and modern infra. I care about clean architecture, measurable impact, and great developer experience (DX) also so features ship fast and safe, also love building an Apps & AI things. for the security side, I bring pentest/audit mindset to every build: threat modeling, fuzzing & invariants, automated checks in CI, and clear, actionable reports. I also provide English technical translation/localization for whitepapers, docs, and UI strings.

Vue.js and Nuxt developer with 2,000+ hours delivered on Upwork, a 100% Job Success score, and Top Rated status. I build production SaaS platforms that scale and I can point to the numbers. WHAT I'VE BUILT Solar energy management platform (France) - Architected a multi-tenant platform supporting 8+ distinct user roles. The installer network grew from 60 to 520 (8.6x) and platform-managed capacity went from 10 MW to 55 MW (5.5x) as I redesigned installer workflows and optimized the project-delivery pipeline. 1,150+ hours on this contract alone. AI-powered learning platform for children (Netherlands) - Built personalized, adaptive learning paths for children with learning differences, adopted by 4,000+ students. Worked as part of a distributed engineering team spanning 5 continents, shipping full-stack features on tight release cycles. E-commerce and e-learning systems (Ethiopia) - Built a payment-integrated e-commerce platform end to end that drove a 25% increase in sales, plus an e-learning system for renewable-energy education now reaching 1,000+ trainees across TVET schools in 5+ regions. WHAT I WORK WITH Frontend: Vue 3, Nuxt, React, Next.js, TypeScript, JavaScript, Tailwind CSS, Pinia/Vuex Backend: Node.js, NestJS, Python, FastAPI, Go Data: PostgreSQL, MySQL, MongoDB, Supabase Also: REST API design, SSR, CI/CD, deployment, third-party and payment integrations BACKGROUND B.Sc. in Software Engineering from Addis Ababa University (GPA 3.74/4.0). Trained at A2SV, a Google-backed algorithms academy, where I put in 1,200+ hours of algorithmic problem-solving — top 1% on LeetCode with 900+ problems solved. That background shows up in how I handle performance bottlenecks and edge cases, not just in shipping features. I also built Geezify, a machine-learning transliteration system for Amharic that reached 77.3% accuracy by training and benchmarking five architectures, and I published the first working-draft paper on the problem. HOW I WORK I ask questions before I write code, because the expensive mistakes happen in the first week, not the last. You get honest estimates, including when something will take longer than you hoped. I send progress updates without you having to chase me, and I respond within 4 hours during my working day. I'm fluent in English and available for long-term contracts. WHO I'M A GOOD FIT FOR Founders and teams building or scaling a Vue/Nuxt product, especially where the app has real complexity — multiple user roles, dashboards, data-heavy workflows, or integrations that need to actually hold up in production. Tell me what you're building and what's currently in your way, and I'll tell you honestly whether I'm the right person for it.
