Quantitative Python Developer – Exchange-Based Trading System

Quantitative Python Developer – Exchange-Based Trading System (Private) Overview We are developing a private, exchange-based quantitative trading system operating in fast, event-driven markets. The system ingests historical and live data, produces proprietary probability-based scores and entry signals, and executes trades via an exchange API with full order lifecycle and position management. Although the underlying markets are non-financial, the execution mechanics, order handling, and risk management are directly analogous to financial exchange trading systems. This is a serious engineering role — not a consumer app, signals product, or website build. Scope of Work 1. Data & Performance Pipeline Extend and structure historical performance datasets Implement clean, reproducible data models Validation and sanity checks Support ongoing ingestion of new data (Data sources and feature logic will be disclosed post-NDA) 2. Scoring Framework & Entry Gates Implement a modular scoring framework with configurable parameters Support multi-component scoring and gating logic Produce transparent outputs (scores, eligibility flags, reason codes) Architecture must allow formula changes without refactoring core code (Scoring formulas and thresholds are proprietary and shared only post-NDA) 3. Exchange Execution & Risk Harden exchange API interaction Market selection, order placement, monitoring, and reconciliation Implement cash-out / hedging logic via offsetting orders Logging, error handling, dry-run and safety controls 4. Backtesting & Reporting (Extension) Backtest entry/exit rules Basic performance metrics (ROI, drawdown, hit rate) Exportable results for analysis Technical Requirements Essential Strong Python API-driven systems Event-driven / stateful workflows Git-based development Highly Desirable Exchange or broker APIs (financial or non-financial) Order lifecycle management and partial fills Streaming data PostgreSQL / SQLite / Parquet Backtesting frameworks Engagement Model Initial paid technical alignment / audit Milestone-based delivery Potential for ongoing collaboration Application Requirements Please include: Examples of relevant systems you’ve built (trading, execution, APIs, data pipelines) How you would architect separation between signals and execution Your experience handling live order risk Confirmation you are comfortable working under NDA once selected Important Notes No proprietary models, formulas, or datasets are shared at this stage NDA and IP ownership agreement required before detailed implementation All work product is client-owned

Revised Golf Club Video Tracking and Analysis Program

Hi, I please need a relatively simple application constructed for video-based golf club tracking and analysis. Previous attempts have been partially successful, so there is some work there that can be referenced and potentially utilized. A standard 2D camera and video are all that are required for acceptable application performance. Simple marker tracking is planned at this time, comprising two visible markers placed at determined, measured locations on a club to be tracked by users. Original videos input into the needed application will be relatively short, limited to perhaps a few seconds or less. The application will initially need to reformat videos to include frame numbers for user and application referencing. After careful examination of the reformatted video by a user as instructed, the user will select just two frames (so four tracking markers) for the application to further work with. Tracking should be performed just manually and interactively for now. So a means should be provided for a user to view, manually place, and precisely adjust computer tracking indicators over each of the four markers in the two frames selected. With that information, combined with specified club measurements input into the application by the user by this point, an initial club tracking result can be graphically and mathematically displayed. That tracking result will typically reveal a preliminary solution for a user (a rotation point location along the length of the club). But due to the nature of the original club movement, a preliminarily calculated rotation point location will usually be incorrect, commonly by a substantial amount. Thus, an additional process involving some fairly basic geometric and mathematic calculations will need to be further applied (will be provided). And a corrected, final rotation point location as calculated will be the result, graphically and mathematically displayed by the application for a user. I will need to test and work with any efforts on my (Windows) desktop. Desktop and web versions are minimally planned for now. So a programming language(s) that could work effectively for both would be helpful. I think R and Python were mostly tried previously, with various pluses and minuses about each. I am open to any other language(s) as well. Added descriptions needed for both the video tracking and solution aspects to accomplish functional success are much more thoroughly detailed in separate documentation. It includes systematic breakdowns of previous failed attempts for reference, what worked well and not so well with them, and the processes and equations to be applied to calculate final solutions. Various elements of intellectual property are involved. So while I can additionally discuss some matters beforehand, an NDA will be strictly required before I will be able to disclose and/or discuss certain information related to the much more detailed documentation. I can provide the needed NDA after reviewing any proposals I might be fortunate enough to receive. While there is no set budget, past failures have to this day prevented me from better validating certain critical elements concerning the needed application on an extremely foundational level. And until such better proof is obtained first, my additional spending on this particular project will be as minimal as possible to say the very least. If and when better validated, I can reevaluate where to go from there. I am open to both project or hourly rate offers, but I cannot seriously consider an hourly rate offer without a guaranteed maximum number of hours stated up front to successfully complete the needed application. Thank you very much.

Data classification

I will share a purely categorical dataset and need it turned into a clear, well-documented end-to-end classification workflow that I can study for academic purposes. Using Python with Pandas, NumPy, scikit-learn, and visualisations in Matplotlib or Seaborn, start with an exploratory review, handle all cleaning and preprocessing (encoding, missing values, feature selection), then build and compare suitable classification models. Sound evaluation—accuracy, precision, recall, F1 or any metric you judge relevant—must accompany the models, followed by a concise discussion of the results and why a particular approach performs best. Please highlight your experience with similar projects when you respond; I value demonstrated know-how over long proposals. Deliverables I expect: • A well-commented Jupyter notebook covering EDA, preprocessing, model training, and evaluation • The cleaned dataset (or the code that generates it) • A brief markdown or slide deck that walks through the methodology, findings, and recommended next steps Clarity of explanation is just as important as model accuracy, as the primary goal is learning from your workflow.
