The assignment is entirely programming-focused. I already have clinical study data that must be reshaped, validated, and exported in full compliance with CDISC conventions, and the existing R scripts only cover part of the workflow. Your role is to expand and refine that code so every dataset produced can be handed straight to a regulatory reviewer without rework. You will be writing fresh functions where gaps exist, tidying up what is already there, and making sure variable names, labels, formats, and metadata match the relevant CDISC structures (SDTM, ADaM, or SEND—whichever you prefer so long as the final output passes compliance checks). Tidyverse or [login to view URL] is fine; staying within base R is fine too, as long as the code is reproducible and easily audited. Deliverables • Clean, well-commented R scripts that run end-to-end on my sample data • A concise read-me explaining package dependencies, execution order, and any configuration steps • Evidence the output conforms to CDISC rules (log messages, validator report, or similar) We will work iteratively: you push a feature branch or script update, I test on my side, and we repeat until the pipeline is complete. Please share a brief note on similar R projects you have done with CDISC or other regulated data standards so I can see your fit.

As someone who has traversed the worlds of electrical engineering, data science, and regulatory compliance, I am confident that my unique expertise matches your needs perfectly. My proficiency in R and with regulated data standards is extensive, which aligns aptly with what you're seeking. I reinforce this capability with considerable experience reshaping and validating clinical data in strict adherence to CDISC conventions. In addition to this, I always seek to bring additional value beyond the immediate task at hand. This would be demonstrated through creating clean and well-commented R scripts for your sample data, concise documentation that outlines package dependencies and execution orders, as well as evidence of conforming to CDISC rules. I understand that regulatory compliance is a matter of utmost importance in your field, and I am committed to delivering work that passes every compliance check. Lastly, my capacity for iteration and collaborative working methodology is exceptional. I am ready to fully immerse myself in the iterative nature of this project - pushing features until we achieve a seamless end-to-end flow. With me on your team, you can rest assured that deadlines will be met, quality will never be sacrificed and your regulatory reviewers will have no qualms about the quality of our outputs. Let's get your project "wired" for success!

Hi there, I have read your project details carefully. As a Data Scientist with deep expertise in R (Tidyverse) and building reproducible data pipelines, I am the ideal candidate to refine your existing scripts and ensure full CDISC compliance. Relevant Experience with Regulated Data: While my background spans various sectors, my work is grounded in strict data standardization. Operational Compliance: I developed standardized data pipelines for an international airport, merging messy operational logs into a strict schema for regulatory reporting. This required ensuring 100% consistency in variable names, formats, and labels—identical to the rigor required for SDTM/ADaM domains. Data Validation: I build automated validation checks (using logic similar to sdtmchecks) to flag inconsistencies before data is exported, ensuring "audit-ready" quality. My Approach to Your Project: Code Refactoring: I will assess your current scripts and modularize them into clean functions using dplyr and purrr for efficient reshaping and metadata application. Compliance Implementation: I will enforce CDISC conventions (variable naming, controlled terminology) programmatically to ensure the output passes validation checks. Iterative Workflow: I am proficient in Git and comfortable pushing feature branches for your review and testing cycles. I am available to review your existing code immediately and start expanding the pipeline. Best regards, Liam Montero Guillemi Data Scientist | R Specialist
