Shi Wen S.

Algorithmic trading systems architect with 25+ years of experience and execution across three distinct industries. I spent 5 years (2002-2007) as a proprietary trader at Opus Trading Fund, a Goldman Sachs subsidiary, managing a $50M institutional portfolio under strict Wall Street risk discipline. That foundation shapes every line of code I write today. From 2008-2018, I worked as a commercial music producer in Atlanta, earning film placements (Paul Blart: Mall Cop, multiple TV series) and publishing deals with ASCAP and BMG. Collaborators include artists currently exceeding 1 billion aggregate streams on Spotify and Apple Music. That decade taught me how to deliver creative work to demanding clients under tight deadlines — a skill that translates directly to custom development work. Since 2018-Present, I've co-founded Wickstrader, a 4-partner quantitative trading operation building production algorithmic systems on the Interactive Brokers JavaScript API. January 2026 — Present Co-Founder, CodaPro.ai LLC Live trading automation platform that converts Pine Script V6 strategies into real broker execution via webhook. Integrates TradingView alerts directly to Tradovate (futures) and Alpaca (stocks/crypto). I lead strategy R&D — building, backtesting, and optimizing quant-grade Pine V6 strategies with honest commission, slippage, and risk controls baked in. Active on MES, MYM, MNQ, MGC, MCL and more. WHAT I DELIVER FOR CLIENTS: - Custom Pine Script V6 indicators and strategies for TradingView - Expert Advisor (EA) development for MT4 and MT5 platforms - Pine Script to MQL5/MQL4 cross-platform conversions - Automated trading systems with webhook integration - Backtesting, optimization, and strategy validation - Risk management and position sizing modules - Strategy audits, debugging, and code refactoring My published work on TradingView under @ArisCodes includes 12+ original indicators in the Confirmed Series library, earning over 1,100 aggregate community likes in just 3 months of publishing, including Delta Volume Pressure (561 likes), Liq Sweep + CHoCH + OB Instant, and ATR Trail Supreme. MY APPROACH: Every deliverable goes through the same institutional-discipline framework I learned on the prop desk. All code is clean, fully commented, non-repainting (barstate.isconfirmed gated), and validated through rigorous backtesting with Calmar ratio optimization. I treat every client project as if my own capital depended on it functioning correctly. WHAT CLIENTS CAN EXPECT: - Fully commented, production-grade source code - Detailed documentation walking through every component - Backtest results where applicable - Unlimited revision consultation during active projects - 30-day bug-fix guarantee post-delivery - Direct, timely communication throughout the build I'm selective about the work I take on and focused on long-term client relationships. I'm particularly well-suited for complex projects where code quality, reliability, and institutional-grade discipline matter more than the lowest bid.
