- Financial Management and Analysis - Programming - Algo Development - Automation - Design I design systems that make money and interfaces that don’t waste your time. I’m a self-funded portfolio manager and programmer with over a decade of experience in crypto and algorithmic trading. I manage a ¥25M+ portfolio (≈$200k USD) and build custom tools that automate, analyze, and execute. I also design clean, user-focused UIs that help businesses work smarter — especially in Japan. What I do best: • Trading automation (Pine Script, Python, Backtrader) • Google Sheets + Apps Script tools (alerts, workflows, dashboards), Selenium, RPA • Custom business tools for Japanese SMEs (localized and client-ready) • UX/UI that actually improves productivity • Web apps with React / Next.js / Firebase / Vercel I don’t overpromise, I deliver. If you need someone who can think like a strategist, build like a dev, and design like a pro, I’m your guy.

I build NinjaTrader 8 systems in NinjaScript C#, live-tested on NQ futures. Automated strategies, custom indicators, ML signal filters, and connection-resilient execution that works when markets move fastest. I trade NQ and ES futures personally with the systems I build. That means I have debugged, in live conditions, every failure mode that brings traders to Upwork. PROBLEMS I HAVE PERSONALLY SOLVED "Strategy enabled, not taking any trades." Diagnosed and fixed across multiple execution architectures. The cause is almost never what you think it is. "NT cancels my stops when I restart. Random orders get submitted." I built a full SaveState/LoadState persistence system using file and SQLite that survives restarts, reconnects, and data feed interruptions. Strategy resumes correctly whether flat, in a bracket, or mid-sequence. Live-tested on NQ. "My FVG indicator fires one bar late. Calculate.OnEachTick freezes NT8 on NY open." Solved. The Calculate.OnEachTick freeze on complex NinjaScript is a specific architectural issue with a specific fix that does not sacrifice signal timing. Built and tested for NQ at full RTH speed. "Strategy behaves differently in live vs sim." Analyzed at the ATM execution level and the platform-managed order level. Causes are different. So are the fixes. "I need NinjaTrader to receive signals from an external API or file." Built REST API polling, file-based feeds, and staged order logic with duplicate-entry prevention. Tested live on NQ. "I want ML to decide whether to take or skip each trade." Built this: Python Flask server, meta-labeling, CPCV walk-forward validation, HMM regime detection, LightGBM, Kelly/Half-Kelly, Deflated Sharpe validation. NinjaScript queries the server before every order. 828 live predictions served on NQ. "I need this to comply with prop firm rules." Trailing drawdown guards, daily loss circuit breakers, session flattening, and consistency rule logic are all encoded directly into ATM execution. Not bolt-ons. WHAT I BUILD Automated NinjaTrader 8 strategies: full execution engine covering entry, SL/TP, ATM bracket management, breakeven, trailing stops, reconnect survival, session controls, and prop firm compliance. Custom indicators: Calculate.OnEachTick optimization, multi-timeframe data series, FVG, volume profile, VWAP, order flow logic, and adaptive signal filtering. Multi-timeframe architectures: 9-timeframe concurrent engine where higher timeframes gate whether the execution timeframe is allowed to trade at all. ML and Python bridges: NinjaScript to Flask/REST integration with meta-labeling, CPCV, HMM, LightGBM, Kelly sizing, and DSR validation. Signal integration: REST API polling, JSON/CSV file feeds, Telegram webhook, staged order queue, and duplicate-entry prevention. Pine Script and TradingView to NinjaScript conversion: one-for-one replication with correct NT8 bar-timing and Calculate mode handling. Prop firm strategy development: trailing drawdown, consistency rules, and daily loss limits encoded at strategy level, tested under MyFundedFutures evaluation conditions. State persistence and reconnect recovery: SaveState/LoadState with SQLite journaling so the strategy survives all disconnection scenarios. CREDENTIALS 12 years delivering analytics infrastructure for ING Bank, BNP Paribas, Janus Henderson Investors, Hermes, and LVMH. That background shapes how I build: clean state management, performance under load, and documentation the next developer can actually maintain.

I build clean, reliable TradingView indicators in Pine Script (v6) from written strategy specs. If you have a defined setup, moving averages, breakout levels, volume/price filters, I turn it into a working, non-repainting indicator: signals plotted on the chart, key parameters exposed as inputs, and a proper alertcondition() so you can set TradingView alerts. My focus is signal accuracy and no repainting, a signal printed on a closed bar stays put. I've built my own Pine v6 signal scanner (SMT divergence + setup detection) plus a backtester, so intrabar logic and confirmation-on-close are second nature to me. I also code in Python for data and automation tasks. I'm newer on Upwork, so I work fast, communicate clearly, and ask the right questions before I write code, not after. You get the .pine file ready to paste, screenshots of it triggering on a recent chart, and clean, commented code you can maintain. Strategy details always stay confidential. Let's build it right the first time.

I am a Senior Full-Stack Software Engineer with a strong backend foundation in .NET (6/7/8) and hands-on experience delivering scalable, secure, production-ready business systems. My core strength lies in building the backend and architecture of applications—designing clean APIs, implementing complex business logic, integrating payments and third-party services, and deploying systems reliably to the cloud. On top of that, I deliver complete solutions by building React / React Native frontends and handling DevOps & deployment, so clients don’t need to manage multiple developers. I have worked on marketplaces, booking platforms, ecommerce-style systems, and enterprise applications, where reliability, performance, and security are critical. What I help clients with Backend & API development using ASP .NET Core Designing scalable systems with Clean Architecture & DDD Authentication & authorization (JWT, OAuth2, Identity) Full-stack application development (Backend-first) Marketplace, booking, and payment-based platforms Third-party integrations (payments, SMS, email, logistics, APIs) Cloud deployment using AWS, Docker, CI/CD Ongoing maintenance, optimization, and scaling Technologies I work with Backend: C# (.NET 6/7/8), ASP .NET Core (Web API, MVC), Entity Framework Core, CQRS, MediatR Frontend & Mobile: React.js, TypeScript, React Native Databases: SQL Server, PostgreSQL, MySQL, MongoDB, Redis Cloud & DevOps: AWS (EC2, S3, RDS), Docker, GitHub Actions, Nginx, IIS Desktop: WinForms, WPF (MVVM) How I work I focus on clean, maintainable code, not quick hacks I communicate clearly and proactively I think in terms of business impact, not just features I build systems meant to scale and last If you’re looking for a developer who can design, build, and ship real-world software systems, I’d be happy to discuss your project.

I build automated trading systems and the data tooling around them. My focus is turning a strategy idea into software that runs reliably: signal logic, backtesting, execution, and the API plumbing that connects it to exchanges and brokers. What I do most: - Trading bots and Expert Advisors in MQL5 for MetaTrader 4 and 5: trend and range filters, regime detection, risk and lot sizing, trailing stops, news and time filters, and clean exit logic. - Python automation: backtesting engines, strategy research, market scanners, and bots that talk to exchange and broker REST and WebSocket APIs. - Data pipelines: pulling, cleaning, and storing OHLCV and tick data in PostgreSQL or SQLite so strategies test on data you can trust. How I work: - I start from your exact rules. Before writing code I confirm entry and exit logic, instruments, timeframes, and risk limits in writing, so what I deliver matches what you meant. - Everything is backtested. I send you a Strategy Tester report, or a Python backtest with equity curve and stats, before you risk real money. - Clean, commented, parameter-driven code you can adjust yourself. Background: BSc in Computer Science, University of Hong Kong. I care about correctness: no curve-fit numbers, no hidden look-ahead, just logic that does what the spec says on out-of-sample data. If you have a TradingView or Pine Script idea, a manual strategy, or an existing EA that needs fixing or optimizing, send me the rules and I will tell you honestly what is feasible and how I would build it.

Take your concept across multiple platforms with Unity! I'm Randy Blain and I've been working daily with the Unity Game Engine for successful commercial applications since 2009 in a full range of capacities including as a coder, developer, art assets producer, and team leader. I have also had a successful career as a monument sculptor, Creative Director, Technical Lead for CTO startups, songwriter musician and fine artist. My focus is on interactive 3D applications and game design and development..One of my long term projects here was for Cognitive Code, the original Markov Chain conversational AI of which patents for were utilized by Google and others. Over that time I have created frameworks, applications and components for AEC industry, BIM data and game companies, entertainers, VJ tools, combat and navigation systems, ARCgis geopositioning, museum kiosks, theatre sized driving sims, eLearning applications, arduino driven interfaces and controllers, used many REST APIs. I have a thorough grounding in mathematics and game mechanics. I read and write Unity C# fluently. I am a problem solver/bug fixer, know how to squeeze performance out of a framework and can oversee a project from start to completion. My most recent immersive 3d interactive client project was for Vizz and Mr Arol Wolford, the gentleman behind the BIM spec and creator of the original Revit.. This involved pipelining Revit architectural files into the Unity engine, tagging all components with BIM specs and having the ability to fully track every object in the project as it was ordered, the vendor ordered from, the cost, date of delivery, date of install. A timeline of the project was developed that allowed project managers to scrub the timeline to see how the project appeared on any given day, in the past or future giving the ability to instantly see where progress on the actual build construction was occurring and on schedule, ahead or behind. Networked chat, guided tours and recording of virtual tours were implemented along with many communications and tracking subsystems. The result of all that work was it brought 3 million in tech venture funding in the door. It was deployed to over 1000 computers at the world's largest architectural firm. I also implemented a VimAEC viewer that was a cut down version of the Vizz application that was featured as a Unity partner on its front page for several months. Other projects I was involved in were an interactive Museum kiosk for The Armory in San Francisco tat was an heuristically embedded info-node application that linked through all the artifacts and history of the institution. Basically you could start by touching any node and it would center and expand revealing text, sounds, videoclips and/or audio with related links surrounding it. Starting at any node one could review the entire history of the institution in the manner that one found most interesting. Another large project was for Jaguar-Land Rover and was a theatrical sized driving sim though San Francisco, Yosemite and along a California coastal highway. I have a comprehensive understanding of game mechanics and 3D interactive systems and UI/UX paired with several decades in digital and fine arts, 3D hard surface and organic/character modeling/texturing/rigging/animating. I have been involved in sound, video and film recording, as well as advertising, artwork creation, direction, engineering and management, illustration and sculpture for over twenty years. My ability to direct the creative design workflow and make efficient use of digital art assets will save you money while resulting in a superior product that competes favorably in an international market. I find the Unity game engine to offer the most flexible and comprehensive currently extant SDK when the aim is to create a cohesive and captivating game or 3D interactive experience. I own a few hundred Unity plugins and have worked with many SDK's across the board. As I have frequently worked with teams in which there are both creative and financial partners involved in a project, I can happily provide documentation that contributes to a cohesive workflow within the organization. A lifelong creative collaborator, it thrills me to be working at a time in history when the combined forces of economic demand and technological advancement have enabled me to enjoy successful artistic expression with others through the captivating medium of the games and 3D Interactive applications.
