PhD-trained computational biologist and machine learning researcher with 10+ years of experience across academia and industry. I build reproducible data workflows, develop generative models, and conduct genomics and bioinformatics research. My passion lies in applying data engineering and machine learning to complex systems—ranging from systems biology to real-world business challenges. My skill set includes: * Data processing, engineering, and machine learning (including applications in finance and trading). * Software development best practices: version control, CI/CD, and production deployment. * Data scraping and use of LLMs for reasoning, automation, and workflow optimization. * Agile-style project management: short development cycles, realistic timelines, and transparent progress reporting through milestones.

I'm an active trader and software engineer who builds quantitative trading systems from the ground up. I develop custom backtesting frameworks, screening tools, and automated trading pipelines in Python to support systematic strategies in US equities, with a focus on clean entry/exit logic, position sizing, and managing drawdown. As someone who actively trades using my own systems, I know the difference between a backtest that looks good on paper and one that holds up in live markets. I regularly work with trading APIs, data sources, and AI tools, including LLMs, MCP integrations, and multi-model setups, to streamline financial analysis and figure out what actually adds edge in a real trading workflow. My work covers the full development process: building reliable data pipelines, implementing and testing rule-based strategies against real performance metrics, and creating tools for every stage of trading, from market screening and signal generation to portfolio backtesting with proper risk metrics.

I’m a full-stack dev and futures trader who’s been in the game 8+ years — building apps on one screen and flipping markets on the other. ⚡ Dev chops: React, Next.js, Tailwind on the front; Node.js, Prisma, Supabase, GraphQL on the back. I ship clean UIs, fast APIs, and production-ready systems without the bloat. ⚡ Trading chops: 8+ years trading futures and coding algos. I’ve built custom indicators, EA, strategies, and bots for TradingView, Quantower, MT4/5, NinjaTrader, and more. My stuff runs deep — order-flow logic, auto execution, risk control, and strategy automation. 🎯 Prop firm focus: I design systems that actually help traders pass evals, stay funded, and scale payouts. High win-rate, risk-tight, built for real accounts. Bottom line: whether you need a next-gen app or an algo bot that pays rent, I deliver both — the code and the trading edge.

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.

Fast-learning problem solver with 3+ years building, deploying, and shipping high-performance software. Started at 17 and grew from junior to lead, owning module/system design and algorithm-heavy, performance-critical work. Trader with 3+ years of strategy design and execution. Co-founder of D&T Systems, where we automate strategies and build algorithmic trading software—research pipelines, execution algos, and risk tooling—to take strategies from idea → backtest → live.

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.

I am a professional trading bot programmer. I started trading in 2013, and started programming bots since 2014. I have a Bachelors degree in Computer Science with First-Class Honors. I am experienced in: MQL4 / Meta Trader4 MQL5 / Meta Trader 5 Ninja Script / Ninja Trader Trading View / Pine Script My work follows a pattern of communicating the specifications for the task until I understand them fully. Then I start implementing the bot while applying rigorous testing both back-testing and live testing. I also follow with the client on the progress and constantly keep in touch.
