Natán Vekselman

At Verifarma, I redesigned serial-number generation for pharmaceutical traceability and built supply-chain optimization features that increased packaging throughput.

I've also built backend services and internal tools at ATC Sports using TypeScript and Node.js, applying automated tests and TDD to catch regressions before deployment. Through freelance work, I've delivered backend integrations connecting e-commerce ERPs to an MCP-based AI analytics layer, alongside tools for retail, travel, and non-profit clients.

I enjoy hard algorithmic problems and competition. I won the Mercado Libre Warehouse Optimization Challenge using Java and IBM CPLEX, and won Investigathon for a formal graph-theory paper solving an original problem.

I'm completing a Computer Science degree at the University of Buenos Aires, where my thesis focuses on an efficient algorithm for the rK-e-free sandwich problem in graphs. Outside work, I've built an algorithmic trading system in Rust, web games, and a competitive programming library, with over 800 Codeforces problems solved.
