7+ 𝐲𝐞𝐚𝐫𝐬 of building crypto wallets, DeFi apps & fintech platforms - from idea to App Store. If you're launching a crypto wallet, DeFi mobile app, trading platform, or fintech product - you're in the right place. I specialize in React Native mobile development for the crypto and fintech space. I don't just write code - I help you ship a product that users actually want to open every day. 𝐖𝐡𝐚𝐭 𝐈 𝐁𝐮𝐢𝐥𝐝 Crypto Wallets - custodial and non-custodial wallets for iOS and Android. Multi-chain support: Ethereum, Solana, TON, BSC, Polygon, TRON and other EVM chains. DeFi and Web3 Mobile Apps - DEX integrations, staking dashboards, yield farming UIs, token swaps, NFT portfolios - all connected to smart contracts via Web3.js and Ethers.js. Fintech Mobile Apps - payment systems, digital wallets, P2P transfers, real-time transaction monitoring, KYC flows, and open banking integrations. Trading Bot Interfaces - mobile frontends for algorithmic trading systems, CEX/DEX dashboards, real-time PnL tracking, copy trading UIs. Smart Contract Integration - connecting your mobile app to Solidity (EVM) or FunC (TON) smart contracts. Secure, tested, production-ready. Crypto Exchange Apps - full-featured exchange interfaces with order books, real-time charts, wallet management, and API integrations (Binance, Bybit via CCXT). 𝐓𝐞𝐜𝐡 𝐒𝐭𝐚𝐜𝐤 On the mobile side I work with React Native, building cross-platform iOS and Android apps with Expo. For blockchain integrations I connect to Ethereum, Solana, TON, BSC, Polygon, TRON and other EVM chains using web3.js and Ethers.js.

𝐒𝐞𝐧𝐝 𝐦𝐞 𝐚 𝐦𝐞𝐬𝐬𝐚𝐠𝐞 - I'll review your idea and suggest the right architecture before we write a single line of code.

I’ve helped my clients launch and improve products used by thousands of users, reduce load times by 30-50%, and deliver features that directly supported revenue-generating flows. I work primarily with React, Next.js, TypeScript, and modern CSS, building production-ready interfaces that are fast, reliable, and easy to maintain. I’m comfortable working across the full stack when needed, connecting frontend logic with APIs, databases, and real-world product workflows. Alongside that, I have a strong interest in Web3 and blockchain systems. I’ve worked with wallet integrations, smart contract interactions, and dApp frontends, and I actively follow developments around EVM, L2 solutions, and scaling technologies. For me, Web3 is not separate -- it’s an extension of building solid, real-world applications. I value clear communication, ownership, and thoughtful implementation. If you’re building something meaningful and need a developer who thinks beyond just code -- let's have a chat.

Is your AI agent a production system or a fragile demo? Most AI agent projects collapse the moment they hit real traffic. 🏆 20+ years architecting production systems at principal engineer level 📊 $100K+ earned on Upwork across 32 architecture projects 🎯 100% Job Success Score, Top Rated Plus on Upwork ⚡ Built an MCP server connecting AI agents to live financial operations on Solana 💼 CEO at Osambit, a 20-person AI agent engineering team ✅ Enterprise Blockchain Architect certified, former Sr Principal Engineer at Nordstrom ⭐⭐⭐⭐⭐ "We've had the opportunity to collaborate with the Osambit team, and it's been a great experience. They're highly professional, responsive, and truly understand the final goal. Their technical expertise and ability to deliver on time have been key to the success." (Alwyn V., IXO World) As an AI Agent Architect with 20+ years of production engineering experience, I build AI agent systems using LangGraph, LangChain, and MCP that run in production, not prototypes that die in demos. Every AI agent project I take on starts with a decision graph - what the AI agent handles autonomously, what escalates to a human, and where it fails safely. That architecture-first approach is why my AI agent systems survive real traffic while cheaper builds collapse on edge cases. 🔶 IXO World (AI agent architecture): full-time Q4 2024 engagement | delivered on time | team collaboration verified by client testimonial above 🔶 Meteora + proprietary DLMM protocol (AI agent + DeFi automation): $81K engagement | MCP server linking AI agents to live trading operations | real-time autonomous execution with human-in-the-loop safeguards 🔶 Roover.AI (AI agent system architecture): intelligent B2B2C roof estimation platform | multi-modal RAG pipeline design | production deployment 🔶 Nordstrom (Sr Principal Engineer, 5 years): architected 9+ enterprise systems | supported 10 offshore engineering teams | supply chain, payment, logistics domains WHAT I DO ✅ AI Agent Architecture: decision graph design, multi-step workflow orchestration, human-in-the-loop control for every AI agent system ✅ LangGraph & LangChain Systems: production AI agent pipelines with state management and tool connectivity ✅ MCP Server Development: Model Context Protocol servers connecting AI agents to real business systems ✅ RAG Pipelines: retrieval-augmented generation grounding LLM answers in your knowledge base ✅ Multi-Agent Orchestration: CrewAI, LlamaIndex, and custom AI agent orchestration for complex agentic AI workflows ✅ AI Agent Security Hardening: prompt injection defense, data leakage prevention, auditability ✅ LLMOps & Production Deployment: tracing, observability, evaluation frameworks, regression testing for AI agent systems ✅ OpenAI & Claude API Integration: enterprise-grade AI agent integration with cost, latency, and failure-mode management WHO I WORK WITH 🎯 B2B and B2C companies building AI agent products, not one-off assistant setups 🎯 Founders and CTOs who need AI agent systems running in production with real users 🎯 Teams with multi-week engagements (4+ weeks minimum), not 5-minute tasks 🎯 Companies that understand AI agent architecture is a design problem, not a prompt problem 🎯 Clients who value senior engineering judgment over the cheapest hourly rate MY PROCESS 1️⃣ Architecture Review: 24-hour turnaround on a decision graph, failure-mode map, and scope estimate for your AI agent project 2️⃣ Design: AI agent flow specification, tool boundaries, escalation rules, evaluation plan 3️⃣ Build: production AI agent system with observability, security, and regression tests from day one 4️⃣ Deploy & Iterate: staged rollout, LLMOps monitoring, iterative refinement of the AI agent based on real usage Send me a message or invite me to your AI agent project.
