Freelancer Overview

I'm a self-taught frontend developer with a CS foundation, but a significant portion of my work both professionally and on the side sits at the intersection of structured data and AI. I've done freelance annotation and AI training work involving text labeling, output evaluation, and classification tasks, and I treat that work with the same rigor I bring to production code: clear schemas, consistent taxonomy, and careful edge-case handling. The differentiator is that I don't evaluate AI outputs as a stranger to them. I build with AI coding tools daily (Claude Code, Cursor) and ship full-stack applications using Next.js, TypeScript, Supabase, and Sanity CMS. That means when I review an AI-generated UI, a code snippet, or a structured response, I'm doing it with the eye of someone who has debugged that exact pattern at 2am. I bring builder intuition, strong written English, and an async-first workflow to every project I take on.

Labeling Experience

Structured Data Modeling & Schema Design (Independent)

Computer Code ProgrammingComputer Programming/Coding

Tools: Sanity CMS, Supabase, PostgreSQL Built and maintained structured content schemas (Sanity) and relational data models (Supabase/PostgreSQL) for production web applications. This work directly mirrors annotation tasks defining categories, enforcing consistency across thousands of records, and resolving edge cases in how data is labeled and stored. Worked with taxonomies for clothing collections, customer records, order pipelines, and student academic data

yes before diving into web development, i worked on tasks involving text annotation, evaluating the accuracy and logic

Computer Code ProgrammingComputer Programming/Coding

form Validation & Multi-Step Input Flows (Student Information Management System) Tools: JavaScript, HTML5, CSS3 Designed multi-step client-side validation flows for student profiling, attendance, and grading. The work required defining clear input rules, handling ambiguous edge cases, and ensuring data integrity at every step,the same core skill set as labeling tasks that need strict schema adherence and consistent categorization across entries.

Freelance Data Annotation & Classification (Various Clients) Tools

TextText Generation

Tools: Platform-specific annotation interfaces Completed text classification, content evaluation, and structured labeling tasks on a freelance basis. Tasks involved applying rubrics consistently, flagging low-quality or ambiguous inputs, and meeting throughput targets without sacrificing accuracy. Familiar with guideline-based review, edge-case escalation, and inter-annotator consistency
