Python Developer – GC-MS Data Analysis & Automated Flavor Recipe Generation System Project Overview We are a flavor manufacturing company developing an internal AI-driven GC-MS automation system. The goal of this project is to: Process GC-MS peak data Match peaks with compound libraries Identify possible natural/synthetic sources Detect marker compounds Estimate ingredient combinations Automatically generate optimized trial recipes (normalized to 100%) This is NOT a simple chatbot or automation project. This is a scientific data processing and algorithm development project. Responsibilities Parse GC-MS peak lists (CSV / Excel exports) Implement compound matching logic (CAS-based matching) Normalize peak area percentages Develop similarity scoring algorithms Ident...

I will provide a corpus of raw call recordings, each in MP3 format, and I need a machine-learning model that can automatically flag fraudulent activity. The model must correctly recognise the three problem categories—Phishing, Robocalls and Telemarketing scams—without human intervention. What I expect you to handle: • Pre-processing: clean the audio and extract features (e.g., MFCCs or spectrograms) that capture speaker and content cues. • Modelling: design, train and fine-tune a classifier; CNN, RNN, Transformer or a hybrid approach is acceptable if it improves accuracy. • Evaluation: deliver precision, recall, F1 and a full confusion matrix for each fraud type so I can judge real-world performance. • Deployment assets: an inference script or small R...

I need an experienced Python engineer who works confidently with AWS Glue to build and manage a small suite of data-integration jobs for a Hyderabad-based project. The core of the work is to design and automate Glue ETL pipelines that pull data from our production databases, catalog it accurately, and transform it into analytics-ready tables. Here is what I expect from the engagement: • Develop, test, and deploy Glue ETL jobs in Python. • Populate and maintain the Glue Data Catalog so new tables are discoverable and properly version-tracked. • Implement efficient transformation logic that cleans, enriches, and partitions data for downstream reporting. • Optimise job performance and cost by selecting the right worker types, job parameters, and database connectio...

I have a Hadoop cluster holding several large data sets, and I need a seasoned PySpark developer who also writes rock-solid SQL. The immediate aim is to connect to the cluster (YARN/HDFS with Hive metastore), develop or refine PySpark jobs, optimise the accompanying SQL, and make sure everything runs smoothly end-to-end. You’ll receive access to a staging namespace plus a sample of the data. Once the logic checks out we’ll promote the code to the full environment. Deliverables • A clean, well-commented PySpark notebook or .py job that executes successfully on the cluster • The corresponding SQL script or view definitions ready for Hive or spark-sql • A concise README detailing execution steps, parameters, and expected outputs Acceptance criteria &bul...
