Hey! I'm Dev, a Full Stack & Algorithmic Trading Developer with 7+ years of experience building trading systems, DApps, and high-performance applications that work in production, not just on paper. My focus is on quantitative and automated trading, building bots that execute strategies across spot, futures, and options markets on exchanges like Binance and Bybit. I work across the full pipeline: signal generation, backtesting frameworks, risk management, portfolio-level delta balancing, and live execution. On the options side, I'm comfortable working with Greeks (Delta, Gamma, Theta, Vega and beyond) to design hedged, multi-leg structures and volatility-aware strategies. On the side, I also build games — from hyper-casual mobile titles to Web3-integrated experiences with real on-chain logic. 💡 What I Can Help You With: Algorithmic Trading Bots - strategy automation, signal systems, live execution across CEX/DEX Backtesting Frameworks - historical data pipelines, performance metrics, slippage/fee modelling Options Strategy Systems - Greeks-based hedging, IV percentile entry timing, multi-layer portfolio delta management Portfolio Balancing & Risk Management - drawdown controls, position sizing, Sharpe/Sortino/Calmar tracking DeFi DApps - staking, yield farming, vaults, smart contracts (ERC-20, ERC-721, custom logic) NFT Platforms, Token Launches & Web3 Frontends Hyper-Casual & Web3 Games - fast prototypes, Android/iOS/PC, Unity, multiplayer logic, ads & IAP integration Full Stack Development - React/Next.js frontends, Node.js/Express backends, PostgreSQL, MongoDB, AWS 🛠️ Core Stack: Python (backtesting, data pipelines, trading systems), Binance & Bybit APIs, Solidity, Ethers.js, React, Next.js, Node.js, PostgreSQL, MongoDB, Docker, Unity I build systems that hold up under real-world conditions, whether that's a Greeks engine tracking a multi-layer hedged portfolio, a DeFi protocol handling on-chain logic, or a hyper-casual game shipping to the App Store. If you want serious infrastructure behind your idea, let's talk.

I build AI systems that don't break. From MVP to Enterprise Scale. 🏆 30+ MVPs delivered | $500K+ raised from last MVP | Got into EWOR with the POC Demo I build resilient, audit-ready data products that handle real-world complexity—I have deployed mission-critical AI Agents and cloud infrastructure across multiple major international airports (including LAX, Southwest Florida, and Birmingham), where 99.9% uptime is mandatory. I combine the speed of No-Code (Airtable/Bubble) with the robustness of custom AI engineering (Python/OCR/LLMs) to deliver scalable MVPs in weeks, not months. CORE COMPETENCIES: Enterprise AI: Custom OCR pipelines, Real-time ML models, and Voice AI infrastructure (built for Cloudax & Legacy Edge). Rapid MVPs: Architectural mastery of Airtable, Softr, Bubble, & Retool coupled with custom backend logic (Python/Node) to bypass no-code limitations. Data Engineering: Complex extraction, normalization, and structured data layers (bullhorn, Salesforce, SQL). FEATURED WORK: Major US Airports: Deployed large-scale cloud + AI systems including custom computer vision models in production. Cloudax: Led voice/AI infrastructure, directly contributing to a $500k raise and startup selected for EWOR Fellowship. Legacy Edge: Architected secure data workflows for high-volume processing. I don't just "build apps." I engineer products that investors trust and users love. Ready to build something reliable? Let’s talk.
