Production-Grade Software & SaaS Architect | Trading Systems Engineer | Pine Script v6 Specialist | 5+ Years I'm the founder of DESLARGE INC, where I architect production-grade software — full-stack web applications and multi-tenant SaaS — with a specialization in trading systems, plus 5+ years of advanced Pine Script v6 development. Production-Grade Software & SaaS: I build the hard class of software: real-money, multi-tenant systems that have to be correct, fast, and fault-tolerant because failure has a financial cost. Architecting a SaaS where users transact real money in live markets — and guaranteeing that one user's capital, state, and orders can never bleed into another's, at scale — is a genuinely demanding engineering problem. I've solved it end to end, alone, over 2.5+ years: multi-tenant architecture with per-user isolation, RBAC, OAuth, subscription tiers and usage-based billing; real-time low-latency data pipelines and concurrency-safe execution; fault-tolerant recovery; and LLM-powered features in production. Flagship — the DESLARGE Trading Platform: A live algorithmic trading platform serving real users across equities, indices, options, and futures. Built on Node.js / Fastify / React / TypeScript / PostgreSQL / Redis, it features per-user runtime isolation (own broker session, trigger engine, and market-data feed per user), a sub-millisecond trigger engine with duplicate-order protection, live broker integration across NSE/NFO/MCX/BFO, AI-driven signals (Claude + a proprietary scoring engine), and quant tooling — backtesting with walk-forward and Monte Carlo, Greeks, and multi-leg spread construction — backed by 6,000+ automated tests. Pine Script v6: High-complexity systems built on genuine OOP — UDTs, methods, stateful patterns, typed arrays — for strategies, custom indicators, pattern recognition, and risk management (Kelly, Monte Carlo, position sizing). I also build and sell premium, professionally-coded indicators. My Approach: I deliver thinking code — clean, documented, scalable, object-oriented. I understand both the engineering and the trading; the intersection is where I work. I'm ideal for projects needing real technical depth: SaaS and trading-platform architecture, multi-tenant systems, real-time/broker integration, or advanced Pine Script v6. Let's build something sophisticated.

I build production-grade software at the intersection of AI, fintech, and blockchain. My work spans the full stack — from backend architecture and API design to polished React frontends — with a focus on systems that handle real money, real data, and real users. Past and current work includes an AI-powered personal health platform with food analysis and a token reward economy; and a custodial crypto trading platform integrating Cobo WaaS 2.0 for a funded fintech startup. What I deliver for clients: AI-integrated applications — Gemini, OpenAI, and Claude APIs wired into production products Crypto exchange infrastructure — Trading platform with rest API & websocket order execution, Cobo WaaS 2.0 MPC custody, KYC integration, VARA licensing support Algorithmic trading systems — MQL4/MQL5 EAs, Python ML pipelines, live deployment on IC Markets and similar brokers Full-stack web and desktop applications — React/Vite frontends, Node.js/Express backends, Supabase (PostgreSQL), deployed on Vercel, Railway, and AWS Smart contracts and dApps — Solidity, Rust, Web3.js, ethers.js across EVM chains and Solana I work independently, communicate clearly, and ship. 100% Job Success · Top Rated Plus.
