What I'm looking for

I’m looking to work remotely for an organization that values collaboration, initiative and open communication. I want to work with people that value my input and know how to reward the value I bring as an individual talent.

At EarlyScape, I engineered a TypeScript psychometric matcher using vector scoring and cosine similarity, then integrated it with Firestore for personalized career recommendations. I also optimized the React front end, improving initial load time by 20% and boosting first-session retention.

For Quivy, I designed and implemented a giveaway management application with a TypeScript and React frontend and a Node.js backend. I developed RESTful APIs with Express and PostgreSQL and automated frontend deployment through Vercel.

At Aptech Teaching Institute, I taught web application fundamentals in HTML, CSS, and JavaScript, and updated the curriculum and assessment style, contributing to a 20% increase in student performance. I’ve also mentored aspiring developers and written technical articles on Rust.
