Freelancer Overview

I am a software developer and AI training specialist with a strong foundation in Python, SQL, and modern JavaScript frameworks. My core expertise lies in evaluating algorithmic logic, writing structured code prompts, and debugging complex outputs to assist in training large language models. Because I actively build and deploy applications using tools like Next.js, Vite, and Tailwind CSS, I bring a developer's eye to AI evaluation, ensuring that generated code is not only syntactically correct but also optimized and production-ready.with hands on experiences on "utility" tools like n8n,make.com Additionally, I specialize in advanced data extraction and automation. I build resilient pipelines using tools like Playwright and Pandas, often integrating LLM APIs via OpenRouter to parse unstructured web data into clean, normalized datasets (JSON/CSV). My dual background in active software development and structured data engineering allows me to handle highly complex AI training tasks, from prompt response writing to rigorous code evaluation.

Advanced Web Scraping & Data Normalization

TextData Collection
Designed and executed complex data extraction workflows targeting JavaScript-heavy, dynamic websites. Utilized Playwright to automate browser interactions for client-side rendering, managed pagination and rate limiting, and used Pandas for rigorous data cleaning. Integrated Apify Actors and LLMs to parse unstructured HTML into strict, normalized formats for clean dataset delivery.

Advanced LLM Training & Technical Code Refinement

Computer Code ProgrammingRLHF
"In this role, I bridged the gap between raw data and high-performance AI. Drawing on my background as a Computer Engineering graduate and my experience with Gair Legal, I focused on refining AI responses to move past 'robotic' patterns. I specialized in RLHF (Reinforcement Learning from Human Feedback) for complex programming tasks in Python and Next.js. My goal was to ensure the model didn't just provide 'correct' code, but 'human-readable' and efficient solutions. I evaluated thousands of prompts to improve semantic understanding and 'Humanized' the AI's tone to match professional standards."

AI Code Evaluator & SFT Specialist (Tendem Project)

Computer Code ProgrammingPrompt Response Writing SFT
"As a lead evaluator, I managed the refinement of a multi-language coding LLM. I focused on high-complexity RLHF tasks, ranking model outputs for Python, JavaScript (React/Next.js), and SQL. My evaluations centered on $O(n)$ time complexity, memory management, and security protocols. I developed a proprietary rubric for 'humanized' code comments, ensuring that the model-generated output met the standards of a Senior Software Engineer while maintaining strict adherence to modern deployment constraints."

Advanced Red Teaming & Safety Alignment

TextPrompt Response Writing SFT
Leveraged Google Cloud AI certifications to conduct advanced "Red Teaming" for enterprise-level agents. I designed complex adversarial prompts to stress-test model guardrails against bias, jailbreaking, and data leakage. I refined thousands of Prompt-Response pairs to improve SFT results, specifically focusing on "Humanizing" refusal mechanisms to be helpful and transparent rather than robotic or dismissive.
