// Career
Full stack software engineer with 5+ years building production web applications in TypeScript, React, Node.js, and Python. At Turing I build the frontend of a human-in-the-loop platform that produces LLM training data, and I build and run Corrija+, an AI grading SaaS for teachers, end to end. Previously led e-commerce builds for clients at PaveCX.
// Main Stack & Expertise
// Experience
- Built the React frontend of a human-in-the-loop annotation platform used by thousands of annotators to produce LLM training data for frontier AI labs.
- Redesigned the task-batch release flow and the evaluator and QA interfaces.
- Made filtering incremental with lazy loading and caching, so users no longer reloaded the full dataset on every change.
- Produced RLHF preference data and gold-standard evaluations of model-generated code.
- Build full-stack SPAs and programming tasks in TypeScript, Python, Java, Ruby, and COBOL to train and evaluate frontier models.
- IH Store (Jun 2024 - Oct 2025): led a team of 2 engineers and 1 designer to build a home decor e-commerce platform from scratch on Deco.cx, scoring 100 on PageSpeed, with ERP, CRM, cashback, and Meta, Google, and TikTok Ads integrations.
- Dilis (Jun 2024 - Sep 2025): architected an AWS-backed event platform for a brand activation campaign: auth, image uploads, and event management.
- True Source, via Wave Commerce (Feb - May 2024): Preact components on Deco.cx from Figma, plus the call center section, accessibility, and SEO.
- Integralys (Nov 2023 - Jan 2024): migrated a legacy PHP app to React and TypeScript from Figma designs.
- Velocità, via TEC4U (Aug - Oct 2023): product listing, product detail, and landing pages on Deco.cx.
- Built a Scrum productivity platform with React, Node.js, and PostgreSQL.
- Also served as product manager and Scrum Master.
- Founded a data and web consultancy for 4 SMBs: sales analysis, customer segmentation, and demand forecasting with Python (pandas, scikit-learn) and SQL.
- Built e-commerce sites with WordPress, PHP, and JavaScript.
- Automated the daily sales-vs-target pipeline with Python and SQL, generating goals for the sales team and saving 40+ minutes a day.
- Built Power BI sales dashboards for Paraíba, later adopted across the entire Northeast region.
// Featured Projects
1. Corrija+ - AI Grading for Teachers
AI grading SaaS for teachers that I build and run solo: React web app, Expo mobile app, and a Node.js API on Google Cloud with async AI processing, payments, IaC, and CI. Cut the initial bundle by 92% with code splitting.
2. ZEPA Machine - OS Simulator
OS simulator for CS students: a TypeScript virtual machine with a custom assembler, scheduler, paged virtual memory, and file system.
