Hi, my name is Javier! I am 26 years old and I am from Spain. I have more than 5 years of experience in Salesforce, mainly as a developer, although I have also worked as a consultant and managed a small team. I am now a freelancer and carry out projects focused on trading. I have worked on long-term structural solutions in large projects related to banks, electricity companies, NGOs, etc. I also have Platform App Builder and Platform Developer I certifications. In addition, I have experience in many other areas of development and infrastructure: database-level programming, REST API design and integration, process automation, Docker environment deployment, Linux system administration, web servers, use of tools such as Git, CI/CD, and working with distributed architectures. I have also worked with FastAPI, Python, C#, websites with authentication, security, tunnels, license control, scraping, VPS management, networks, proxies, etc. I adapt quickly, enjoy learning new things, and solving real technical problems. When I take on a new challenge, I don't stop until I succeed.

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.

In the AI era, writing the code is the easy part — architecting a trading system that survives real markets is the hard part. That's where I come in. I'm a Senior Quant Systems Architect and an active trader since 2012, with two decades in financial markets and software. I don't just build trading bots — I've lived the markets they run in: the gaps, the halts, the slippage and drawdowns that quietly blow up systems built by people who never traded. Whether you trade Forex, Stocks, or Crypto, I turn your manual strategy into a fully automated, risk-controlled, data-driven system. My Core Expertise Includes: - **Trading Platforms & Language Syntax**: MetaTrader 4 & 5 (MQL4/MQL5), TradingView (Pine Script), NinjaTrader (C#). - **Execution Engines & EA Architecture**: Building modular Expert Advisors (EAs), custom indicators, and automated order routing systems optimized for fast fill rates and minimal slippage. - **Quant Infrastructure & Data Pipelines**: Custom Python pipelines for historical market data ingestion (Databento, ThetaData), cleaning, and time-series database design (TimescaleDB, Clickhouse). - **Crypto & Exchange Integration**: High-frequency API bridges and WebSockets integration for major exchanges (Binance, Bybit, Coinbase Pro) with redundant rate-limit handling. - **Visual Analytics**: Interactive React-based dashboard charts (Lightweight Charts) connected to live WebSocket feeds for real-time strategy monitoring. Why Work With Me? - **Risk-First Architecture**: Hardcoded drawdown limits, dynamic position sizing, and circuit breakers designed to protect capital in fast-market conditions. - **Strict Confidentiality**: Your proprietary trading algorithms, logic, and intellectual property are protected under strict NDA and absolute confidentiality. - **Mathematical Backtesting Integrity**: Rigorous historical analysis using event-driven Python engines (Backtrader/custom engines) to prevent look-ahead bias and overfitting. - **High-Performance Code**: Low-overhead execution logic written in C#, C++, and optimized Python (Pandas/NumPy) for sub-millisecond local processing. Let's eliminate human emotion from your trading and let the code do the heavy lifting. Send me a message with your strategy or project details, and let's discuss how we can build a production-ready execution system.

I build trading algorithms the way a Swiss watchmaker builds gears - precise, reliable, and built to run while you sleep. For over a decade I’ve turned market noise into structured logic, crafting bots that execute faster than human reflexes and complain far less. I specialise in Python, quantitative modelling, strategy automation, and multi-exchange integration. Whether you need a market-making engine, a backtesting framework, or a stealthy bot that reacts before the candle closes, I design systems that stay sharp in any market weather. If your trading workflow feels clunky or manual, I’ll turn it into something smooth, automated, and quietly brilliant like an algorithm having a good day.
