    I have a dataset that is growing quickly and a business case ready for machine-learning insights. What I need now is someone who can take the project from raw data all the way to a production-ready model: that means designing the data pipeline, choosing and training the model, fine-tuning for accuracy and latency, then packaging everything for a reliable, scalable deployment. Here is what success looks like for me: • A repeatable pipeline (Python, SQL, Airflow or equivalent) that ingests the source data, performs cleaning / feature engineering, and stores curated tables. • Well-documented training notebooks or scripts using standard frameworks (scikit-learn, TensorFlow or PyTorch) together with clear evaluation reports. • Fine-tuning that pushes performance to an agr...

    We brought in this developer to debug a production RAG pipeline that had quietly degraded after a dependency bump. The pipeline — built on LangChain, FastAPI, and Supabase pgvector — was still returning results, but retrieval quality had clearly dropped: wrong chunks, wrong document sections, irrelevant context making it into answers. The scope was well-defined: audit our chunking config, confirm embedding model consistency between ingestion and query time, check our pgvector distance/index setup, and run live test queries to surface exactly where retrieval was going wrong. He delivered on every point. The root cause turned out to be a silent embedding model mismatch introduced during a langchain-openai upgrade — something easy to miss and painful to debug without knowin...

    Minor PHP Enhancements and Fixes
    1 ชั่วโมง left
    ยืนยันแล้ว

    My PHP application is already online and fully connected to MySQL; it just needs a couple of light touches. In total I expect two-to-three quick updates, the most notable being the addition of a small feature that slots straight into the existing codebase. The other tweaks are straightforward logic or display adjustments—nothing structural, no schema changes, and certainly no rebuild. The code is plain PHP with direct SQL (no frameworks). A solid grasp of PHP, MySQL, and rapid debugging will let you dive in, trace the current flow, and wrap things up fast. Once we’ve talked through the exact lines to touch, I’ll share the repository and a database dump so you can run it locally. Deliverables • Updated PHP files with the new feature and minor fixes implemented &...

    Dynamic Power BI KPI Dashboard
    กำลังหมดเขต left

    I need a seasoned Power BI developer to turn a very large, highly-granular data set into a single, dynamic dashboard focused on monitoring key operational-efficiency KPIs. Here’s the landscape you will step into: our raw information sits in both SQL databases and a series of regularly exported Excel/CSV files. I want a model that connects to each source, transforms the data so that it’s truly analysis-ready, and then visualises the metrics that matter—cycle times, throughput, bottleneck alerts, utilisation rates and any supporting drill-downs we decide to add. Scope of work • Build or optimise the data model, including merge logic between SQL and CSV tables, DAX measures, and relationships that guarantee a fast, responsive user experience even when the data vol...
