You will get a custom AI-powered web tool built with React, Claude API, and Supabase
Rising Talent
Project details
You need a tool that actually works in your domain — not a generic chatbot, but something precise, deployed, and ready to use.
I build custom AI-powered web applications using Claude API or OpenAI, with React frontends, PostgreSQL databases, and proper user authentication. My background is unusual: biological-chemical technical training, bioinformatics studies, and a 14-month cybersecurity SOC analyst program — which means I understand technical domains most developers don't.
My most recent project: Karis, an AI job application tool built and deployed in 48 hours. It reads a job posting, rewrites a CV specifically for that role, generates PDFs, and tracks every application with full multi-user authentication. Not a prototype — a working product.
I specialise in health tech, life sciences, cybersecurity tools, and career tech. I deploy to Vercel, AWS, or Google Cloud. I'm direct, I deliver working software, and I tell you if something won't work before I start building.

About Elina
AI Tool Developer
Berlin, Germany - 4:13 pm local time
I'm Elina — I trained as a biological-chemical technical assistant, studied bioinformatics, completed a 14-month cybersecurity SOC analyst program, and have spent the last two years building full-stack AI applications. I read research papers and translate them into working software. That combination is rare.
What it means for you: when you explain your problem, I understand it the first time. No three discovery calls to grasp what your product does.
Recent work: Karis — an AI-powered job application tool I built and deployed in two days. It reads a job posting, rewrites a CV specifically for that role using Claude, generates downloadable PDFs, and tracks every application in a PostgreSQL database with full authentication and per-user data isolation.
I built it because I needed it. That's how I work.
What I build:
— Custom AI tools using Claude API or OpenAI
— Full-stack React + Supabase web applications
— Document and PDF generation tools
— Security and compliance dashboards
— Health and science data tools where accuracy matters
How I work:
I'm direct. I'll tell you if your idea has a problem before I start building. I deliver working software, not mockups — and I test it myself before calling it done.
