Computer Code ProgrammingComputer Programming Coding
I worked on a project focused on reviewing and validating Infrastructure-as-Code tasks created by others. My role was to check the clarity and accuracy of prompts, code implementations, and automated tests across tools like Terraform, AWS CDK, Pulumi, and CloudFormation. I reviewed code written in languages such as Python, TypeScript, and HCL to ensure the tasks were realistic, well-defined, and functionally correct. The goal was to improve overall quality by identifying issues, clarifying ambiguous requirements, and making sure the submitted solutions worked as intended.

PR writer

Computer Code ProgrammingPrompt Response Writing SFT
**PR Writer Project — Description** This project involved reviewing and improving AI-generated pull requests related to Infrastructure as Code (IaC) and software engineering tasks. The scope included validating code changes, running and reviewing tests, identifying bugs or missing logic, and providing PR-style feedback. The work required evaluating multiple model outputs, selecting the better solution, and iterating until the change was production-ready. **Scope & Tasks:** * Code review and evaluation of AI-generated PRs * Data labeling by ranking model responses and providing structured feedback * Validation of logic, correctness, and test coverage * Iterative improvement through PR-style review cycles **Project Size & Quality Measures:** * Worked across multiple coding tasks and model outputs * Quality ensured through test verification, correctness checks, and structured review criteria (logic, robustness, clarity, and readiness)
