I’m looking for a Python/data science freelancer to help build a data pipeline and prediction model for UFC betting. The initial focus will be gathering, cleaning, and structuring historical UFC fight data and historical betting odds. If the engagement goes well, there is an opportunity to continue into feature engineering, machine learning, backtesting, model calibration, and bet-sizing. The ultimate goal is a system that estimates a fighter’s probability of winning and compares that probability against sportsbook odds to identify potentially mispriced bets. Initial Scope * Gather historical UFC fight and fighter data from reliable sources * Gather historical betting odds where available * Clean, normalize, and merge the datasets * Build point-in-time features using only information that would have been available before each fight * Prevent look-ahead/data leakage * Create a repeatable process for adding future UFC events and updating the dataset * Document data sources, assumptions, and methodology Potential later work includes below + reccomendations from the freelancer: * Logistic regression / Elo baseline models * XGBoost, LightGBM, or similar ML models * Probability calibration * Walk-forward historical backtesting * Comparison against no-vig sportsbook implied probabilities * Betting thresholds and bankroll sizing * Model diagnostics and performance tracking Important Requirement: Transferable System I am not looking for a black-box model that only the freelancer can operate. I have some prior programming experience but am rusty with Python, so clear code and practical documentation and handoff are important. All code, datasets, scripts, notebooks, documentation, and model files created during the project must be transferred to me. The system should be organized and documented so that I can understand the workflow, run the model myself, update it with new fight data, and continue improving it after the engagement. Ideal Candidate Experience with Python, pandas, data scraping/API integration, machine learning, time-series or sports-model backtesting, and probability calibration is preferred. Experience with sports betting or UFC data is a plus but not required. When applying, please briefly describe relevant projects you have completed, your proposed approach to the initial data-gathering phase, and an estimated cost or number of hours for that phase.

Someone to build machine learning pipeline and be proficient

I have an online learning platform for kids and I want someone who is good in Artificial Intellegence and loves children to join our team to teach them Artificial Intellegence based in USA. This could be a long-term project. Active and Retired Tech Teachers are welcome to apply.

The objective is to develop an AI model that detects and classifies Longitudinal and Transverse Cracking (LTC) in asphalt airfield pavements, in accordance with ASTM D5340-24. The model will use fused Digital Elevation Model (DEM) and imagery data to identify cracks, measure their extent, and assign a severity level (Low, Medium, or High) based on the standard's width and spalling criteria. The output will support the broader Pavement Condition Index (PCI) workflow used across the company's 85-model system. What you'll need to do: • Access and understand the provided DEM and imagery data, along with existing labels • Build a pipeline that fuses DEM and imagery to detect cracks and measure their length and width • Train a model to classify each detected crack as Low, Medium, or High severity per the ASTM thresholds • Apply the standard's exclusion rule so distresses are not double-counted where other cracking is already recorded • Validate the model's outputs against the team's verified ground truth and report accuracy • Deliver the trained model along with a short write-up of results and any limitations

CodeAI is looking for an experienced educator with knowledge of AI concepts and familiarity with high school classrooms to review lessons for a new advanced AI course designed for Career and Technical Education (CTE) pathways. In the course, Students learn how AI systems work and get hands-on experience working with models and data in Python. The course is aligned to an industry-recognized credential. Responsibilities - Review each lesson (slides with speaker notes, platform levels, handouts) before it is finalized, flagging where it assumes knowledge students may not have, where directions are unclear, and where timing looks unrealistic. - Give written feedback on pedagogy, student engagement, classroom feasibility, and technical accuracy, with specific comments anchored to the slide or level they refer to. - Catch technical errors in how AI concepts are explained and in the code students are asked to read or run. - Turn each lesson around within about a week and coordinate directly with the development team. Who is a fit - Experience teaching AI or machine learning as a course. - Preferred: Experience teaching high school CS/AI courses, ideally including a project-based or CTE course. - Intermediate to advanced knowledge of AI and machine learning. - Fluent in Python; ideally with experience using it to work with models and datasets. - Experience giving detailed written feedback on curriculum or instructional materials. - Reliable weekly availability during the school year. - Preferred but not required: Familiarity with the Azure AI Fundamentals certification pathway, or a comparable one.

AI Architect & Autonomous Agent Engineer (Full-Time, US-Based) Own a Live Production Agent Fleet WHAT THIS IS I run a small, profitable company with an unusual amount of automation behind it. A fleet of autonomous AI agents runs our internal data operation unattended for roughly 12 hours a day, every day. It is real production infrastructure that the business depends on. This is not a "build me a chatbot" job and it is not greenfield. The system exists, it runs daily, and mistakes cost real money. Multiple independent pipelines run in parallel, each doing multi-stage automated research, each calling paid third-party APIs at several points, each with its own quality gates and delivery step. Tens of thousands of records have moved through it. I have been operating and extending this system myself. I need someone to own it so I can stop being the bottleneck. This is an architect role and a builder role at the same time. You will design the system AND write the code AND debug it at 6pm when an agent has done something confident and wrong. There is no team under you to hand it off to. If that split appeals to you, keep reading. I will describe the domain and the specifics on a call, under NDA. What I can tell you publicly is the engineering problem, which is below and is genuinely the interesting part. WHAT YOU WOULD OWN 1. ARCHITECTURE AND AGENT DESIGN - Own the overall design: how the pipelines fit together, where state lives, what runs where, and what happens when any piece fails - Build and maintain autonomous agents that run for hours without a human watching, using Claude Code and Codex - Design the guardrails: quality gates, fail-closed checks, regression tests,and audit trails so an agent cannot silently ship bad work - Debug agents that did the wrong thing confidently, which is the hard part 2. MULTI-DEVICE FLEET ORCHESTRATION - Scale from one machine to many machines running the same pipelines at once - Solve the coordination problems that come with that: shared claim and lock systems so two machines never do the same paid work twice, distributed state, race conditions, safe failure modes - Build the setup and sync tooling so a new machine can be onboarded quickly and every machine runs identical, current logic 3. INTEGRATIONS AND DATA PLUMBING - Cloud spreadsheets and file storage used as coordination and reporting layers across machines - Several third-party vendor APIs, some of them metered and billed per call - Reporting that a non-engineer can actually read and trust 4. QUALITY AND COST CONTROL - Every paid API call should be justified and never duplicated - Build measurement into the system so we know our unit cost and can improve it deliberately, not by guessing WHO THIS IS FOR You will do well here if: - You have shipped agentic systems that run unattended, not just prompts that work in a demo - You think like a systems engineer: idempotency, locking, retries, race conditions, failing closed, and knowing the difference between "it returned 200" and "it actually worked" - You are comfortable in Python, APIs, and the command line - You test your own work adversarially and assume your first answer is wrong - You can explain a technical tradeoff to me in plain language without making me feel stupid or hiding the risk - You are comfortable working on something you cannot put in a public portfolio You will not do well here if you need tickets written for you, if you have only worked on greenfield projects, if you want to architect without implementing, or if you are more excited about model choice than about whether the pipeline is correct at 2am with nobody watching. LOGISTICS - Full-time, long-term. This is an ownership role, not a one-off project. - US-based required. Significant overlap with US Eastern hours. - NDA before we get into specifics. HOW TO APPLY Skip the generic cover letter. I will read all of these and ignore anything that looks templated. Please answer these three questions: 1. Describe an autonomous system you built that ran without supervision. What broke, how did you find out, and what did you change so it could not happen again? 2. Two machines are running the same pipeline against a shared queue of work items. Each item costs money to process. How do you make sure no item is ever paid for twice, and what happens when one machine dies mid-task? 3. What is a mistake an AI agent made in something you built that you did not catch until it had already caused damage? Short and specific beats long and polished. If your answer to #2 is one paragraph and correct, you are ahead of most applicants.
